ALT TEXT: "Best free illustration packs for SaaS and app design in 2026 — flat, character, hand-drawn, isometric, 3D, and abstract styles from unDraw, Storyset, Humaaans, and more"

-->

You are designing a SaaS landing page, an app onboarding flow, an empty state for a new feature, or marketing pages for a product launch. You need illustrations. You do not have the budget for a custom illustrator, and you do not want your product to look like every other SaaS landing page using the same unDraw blue character pointing at a laptop. You search "free illustration packs for SaaS" and the SERP gives you 30 libraries in a random pile, no clear way to know which style fits your brand, and no guidance on the licensing differences that matter for commercial work. Every listicle treats "illustrations" as one category. They are not.

This guide separates them by style. The free illustration packs that actually work in SaaS and app design in 2026, organized by what aesthetic each library produces: clean flat, character-driven, hand-drawn, isometric, 3D, and abstract. Every pack named with the style, the typical SaaS use case it fits, the license terms, and where it falls short. No "100 free illustration websites" with no differentiation. No paid-disguised-as-free libraries that watermark exports.

A note on the 2026 illustration landscape before the list. Three shifts changed how SaaS teams use illustration. Product screenshots replaced generic illustrations in many SaaS heroes: the "show the product, not a cartoon" school of thought won the 2024-2025 debate for hero sections. Illustrations now live primarily in empty states, feature explainers, onboarding flows, and marketing pages where the screenshot does not exist yet. AI-generated illustrations became viable but contested: free libraries that explicitly market "hand-crafted, no AI" as a quality signal exist alongside AI-powered tools producing on-demand illustrations. One library per project became the consensus best practice; mixing styles from multiple libraries produces visual inconsistency that hurts the design more than no illustration would.

Skip to the comparison table for the short version. Read on for the reasoning behind each pick.

All 12 illustration libraries in this guide are curated on Mantlr — with license verification, style notes, and direct links. No hunting across 12 different sites.

All libraries have free tiers usable for commercial work; verify per-library license terms. Most ship SVG (editable) and PNG; some include Figma files. The "one library per project" rule applies: mixing styles produces visual inconsistency that competing libraries explicitly warn against in their own documentation.

How to read this list: pick the style first, then the library

Before the libraries, the framework. SaaS illustration in 2026 splits into six distinct aesthetic styles, each with different brand associations:

Clean flat with single accent color. The canonical SaaS aesthetic established by unDraw and adopted across thousands of startup landing pages 2019-2024. Reads as friendly, professional, generic. Risk: looks like every other SaaS site.

Character-driven with diverse representation. Humaaans and Open Peeps established the "modular characters" pattern. Reads as inclusive, human, modern. Best for team pages, user-focused marketing, products with a human element.

Hand-drawn, warm, slightly imperfect. Lukasz Adam and Charco lead this style. Reads as authentic, indie, crafted. Best for personal brands, indie SaaS, products positioning against corporate alternatives.

Isometric (30-degree perspective). ManyPixels and a few others. Reads as technical, infrastructure-focused, dimensional. Best for developer tools, DevOps, infrastructure SaaS, and products visualizing systems or data flows.

3D rendered shapes and objects. Shapefest and adjacent libraries. Reads as premium, contemporary, marketing-grade. Best for hero compositions, feature highlights where you want a "premium feel" without character illustrations.

Abstract, editorial, intentionally imperfect. Absurd Design is the canonical example. Reads as creative, intellectual, distinctive. Best for products positioning around creativity, content, or thinking; not for standard B2B SaaS.

Pick the style that fits your brand positioning first. Then pick the library inside that style. A SaaS targeting enterprise infrastructure buyers using Absurd Design's surrealist art looks confused; a creative tool using clean flat unDraw illustrations looks generic. Brand-style alignment matters more than which specific library you choose within a style.

Clean flat illustrations (single-accent color)

The dominant SaaS illustration style of 2020-2024. Still useful when you want a friendly, professional aesthetic without character complexity.

1. unDraw

Best for: SaaS landing pages, onboarding flows, empty states, presentations | Style: Clean flat with single accent color | Customization: One-click color picker (any hex code) | License: Free, custom open license, no attribution required, no commercial limitations except you cannot resell the illustrations as a pack

unDraw is the canonical free SaaS illustration library, created by Katerina Limpitsouni. The brilliance is the one-click recoloring: pick your brand's primary accent color, and the entire library of 500+ illustrations instantly adapts. The illustrations themselves are minimalist SVGs covering tech, business, communication, lifestyle, abstract concepts, and more.

What makes unDraw the default starting point for most SaaS work: speed plus brand fit. You go from "I need an illustration for this empty state" to "I have a brand-matched SVG ready to drop in" in 90 seconds. The open license eliminates licensing friction entirely; the only restriction is you cannot redistribute the illustrations as a pack.

Where unDraw falls short in 2026: overexposure. Thousands of SaaS sites use unDraw illustrations, which means leading with unDraw signals "I used the free pack everyone uses." For products where visual differentiation matters more than time-to-launch, unDraw is the starting point you customize beyond recognition rather than ship as-is. The single-accent-color limitation also constrains visual range; for richer color palettes, Storyset is the alternative.

2. Storyset (by Freepik)

Best for: Marketing pages, presentations, multi-style projects | Style: Flat, animated, customizable | Customization: Full color editor, animation options, character variants | License: Free with attribution to Freepik/Storyset; paid Premium removes attribution

Storyset is the most-feature-rich free flat illustration library in 2026. The customization editor lets you adjust character poses, accessories, and colors before downloading. Animated SVG and Lottie versions ship for free, which means you can drop an animated illustration into a landing page without commissioning motion design.

What makes Storyset useful beyond static unDraw alternatives: animation. For modern SaaS marketing pages where subtle motion adds polish, Storyset's free animated illustrations cover the use case completely. The style variations (Rafiki, Bro, Amico, Pana, etc.) give you visual range across a multi-page site without leaving one library.

Where it falls short: attribution requirement on the free tier. For commercial work where you cannot link back to Freepik in your footer, the paid Premium tier ($9.99/month) removes attribution. The visual style is opinionated enough that Storyset illustrations are recognizable as Storyset across thousands of sites; differentiation requires significant customization or pairing with non-Storyset assets.

Character-driven illustrations (people and personas)

For products where human representation matters: team pages, user-facing marketing, onboarding flows that introduce personas.

3. Humaaans

Best for: Team pages, user persona visuals, diverse character representation | Author: Pablo Stanley | Style: Modular flat characters, mix-and-match parts | License: Free under CC BY 4.0 (attribution required); commercial use allowed

Humaaans by Pablo Stanley pioneered the "modular character system" approach: bodies, faces, hair, clothing, and accessories ship as separate SVG components that you combine into custom characters. The result is genuine diversity in your illustrations (different skin tones, hair styles, body types, outfits) without commissioning custom artwork.

What makes Humaaans the default for human representation: the modularity. Most character illustration libraries ship fixed characters; Humaaans ships a system for building characters. For team pages where stock illustration's homogeneity is a brand problem, Humaaans solves it directly.

Where it falls short: the CC BY 4.0 license requires attribution to Pablo Stanley, which most product teams cannot accept in production. The workaround is buying out the attribution requirement (contact the creator) or using the system for prototype/internal work and commissioning custom illustrations for production.

4. Open Peeps

Best for: Casual brand aesthetic, hand-drawn character work, onboarding | Author: Pablo Stanley | Style: Hand-drawn modular characters | License: Free, CC0 (no attribution required, public domain)

Open Peeps is Pablo Stanley's CC0-licensed alternative to Humaaans. Same modular character system, hand-drawn aesthetic, but without the attribution requirement. For commercial work where you want diverse character representation without the licensing friction, Open Peeps is the strongest free choice in 2026.

What makes Open Peeps the right pick over Humaaans for most commercial work: the CC0 license. No attribution, no restrictions on commercial use, no licensing risk. The trade-off is a different aesthetic: Open Peeps is hand-drawn rather than the cleaner flat style of Humaaans, which may or may not fit your brand.

Where it falls short: the hand-drawn style is opinionated. For SaaS products positioning as polished and corporate, Open Peeps' sketchy aesthetic reads as too casual. For indie SaaS, content tools, education products, and consumer apps, it fits well.

Hand-drawn illustrations (warm, indie, authentic)

For brands positioning against corporate alternatives or products where authenticity is the differentiator.

5. Lukasz Adam Illustrations

Best for: Indie SaaS, personal brand sites, content products | Author: Lukasz Adam | Style: Hand-drawn vector with warm color palette | License: Free for personal and commercial use, no attribution required for the free pack

Lukasz Adam's free illustration pack ships 100+ hand-drawn vector illustrations with a warm, slightly imperfect aesthetic. The illustrations cover SaaS-relevant topics (working from a laptop, team collaboration, communication, achievement) but in a style that feels human rather than corporate.

What makes Lukasz Adam useful for SaaS in 2026: differentiation from unDraw. Most SaaS landing pages using free illustrations end up looking similar because they pull from the same handful of libraries. Lukasz Adam's hand-drawn style stands out without being so quirky it undermines brand credibility.

Where it falls short: smaller library than unDraw or Storyset. You will exhaust the pack on larger projects and need to commission custom work or switch libraries. The hand-drawn style also locks you into a specific brand aesthetic that does not fit enterprise B2B sales motions.

6. Charco

Best for: Empty states, error pages, 404 illustrations | Style: Minimal hand-drawn, clean line work | License: Free for personal and commercial use

Charco is a small, specialized free pack focused on UI states most products need: empty states, 404 errors, "no internet," "under construction," "no results found." Sixteen illustrations covering common scenarios in a clean, hand-drawn outline style that fits most product UI brands without major customization.

What makes Charco the right pick for what it does: focus. It does not try to be a library for everything. The 16 illustrations solve a specific, recurring problem (UI states) that more general libraries handle worse because they prioritize breadth.

Where it falls short: only 16 illustrations. For anything beyond UI states, you need another library. The hand-drawn aesthetic also constrains brand fit; for purely corporate SaaS, the casual line work may feel off-brand.

Isometric illustrations (technical, dimensional)

For products visualizing systems, infrastructure, data flows, or technical concepts.

7. ManyPixels free isometric illustrations

Best for: Developer tools, DevOps, infrastructure SaaS, technical products | Style: Isometric (30-degree perspective), flat | License: Free, MIT

ManyPixels offers one of the few free isometric illustration libraries in 2026. The isometric style works specifically well for products that visualize systems: how data flows, how components connect, how infrastructure is composed. Most free libraries skip isometric entirely or include only a few token isometric illustrations; ManyPixels treats it as a core style.

What makes the isometric style valuable for technical SaaS: it conveys dimensionality and structure without character illustration. For developer tools, infrastructure platforms, and B2B technical products where humans are not the focal point, isometric illustrations communicate "this is a system, this is how parts connect" more effectively than flat or character-driven alternatives.

Where it falls short: opinionated style. Isometric does not fit consumer apps, lifestyle products, or warm-brand SaaS. The library is also smaller than unDraw or Storyset.

3D illustrations (premium, contemporary)

For hero compositions and marketing pages where you want a "premium feel" without committing to character illustrations.

8. Shapefest

Best for: Hero sections, feature highlights, premium marketing visuals | Style: 3D rendered geometric shapes, objects, and abstract compositions | License: Free with attribution; paid tier removes attribution

Shapefest ships 160,000+ 3D rendered shapes and objects (cubes, spheres, organic shapes, hands holding objects, abstract compositions) in a clean rendering style. For marketing pages where you want the 2024-2026 premium-3D aesthetic without commissioning custom 3D work, Shapefest delivers production-grade output at zero cost.

What makes Shapefest the right pick: the rendering quality matches what previously required Cinema 4D or Blender expertise. For hero compositions, feature section visuals, and "premium SaaS" marketing aesthetic, Shapefest assets ship faster than custom 3D and look better than free 3D alternatives.

Where it falls short: attribution required on the free tier; the paid plan (Shapefest+ at $99-199/year) removes this. The rendered nature means assets are PNGs rather than editable 3D files: you cannot adjust lighting, angle, or material from the source. For deeper 3D customization, see the free 3D icons and assets guide on Mantlr for libraries that ship source BLEND/glTF files.

Friendly and multi-style libraries

For projects where you want variety within one library or need flexibility across multiple aesthetic contexts.

9. PixelTrue

Best for: Startup SaaS, mobile app marketing, projects needing volume | Style: Friendly flat, colorful, with animated variants | License: MIT for the free tier (no attribution); paid for more variants

PixelTrue ships 500+ free illustrations and animations updated weekly. The primary style is clean, friendly, professional, with colorful characters and scenes in a polished aesthetic that fits startup SaaS, tech blogs, mobile apps, and marketing presentations. The free animated Lottie files add a layer of motion most free libraries skip.

What makes PixelTrue useful: the breadth plus the animation. For SaaS projects needing many illustrations across landing page, blog, social media, and product UI, PixelTrue covers more use cases in one consistent style than libraries half its size. The animation availability removes the need for separate Lottie sourcing.

Where it falls short: the visual style is recognizable. PixelTrue illustrations on a SaaS landing page read as PixelTrue illustrations to anyone familiar with the library. For maximum differentiation, customize the colors and combine with non-PixelTrue assets.

10. Blush (by InVision community)

Best for: Multi-artist illustration variety, brand exploration | Style: Varies by artist collection | Customization: Mix-and-match in Blush editor | License: Free tier limited; paid tier ($9-19/month) for full commercial use

Blush is the multi-artist illustration platform with collections from dozens of different illustrators in different styles. The free tier gives access to a subset of collections; the paid tier unlocks the full library and commercial use without attribution.

What makes Blush different from single-style libraries: variety. If your brand cannot commit to one illustration style and you need flexibility across different product surfaces (marketing, product UI, blog, social), Blush's multi-artist collection gives you that range in one tool.

Where it falls short: the free tier is genuinely limited. For most commercial SaaS work needing illustrations beyond exploration, the paid tier becomes necessary. The variety also undermines the "pick one style per project" rule: Blush is at its strongest when you commit to one collection within the platform rather than mixing across many.

11. DrawKit (free tier)

Best for: Marketing pages, app design, polished flat and 3D illustrations | Style: Polished flat, with some 3D variants | License: Free tier with attribution; paid Premium for full commercial use without attribution

DrawKit's free tier offers polished flat illustrations and a smaller selection of 3D-rendered illustrations. The aesthetic skews more polished and "designed" than unDraw: illustrations look like they came from a professional illustration studio rather than an open-source community effort.

What makes DrawKit the right pick over unDraw for some projects: visual polish. The DrawKit aesthetic reads as more premium, more deliberately crafted. For SaaS marketing pages targeting enterprise buyers where polish matters more than reach, DrawKit's free tier produces better-looking output.

Where it falls short: smaller free library than unDraw or Storyset. The paid Premium tier ($59-199 depending on the pack) unlocks the full library and removes attribution requirements.

Abstract and editorial illustrations

For products positioning around creativity, content, or intellectual differentiation.

12. Absurd Design

Best for: Creative tools, content products, editorial brands, products positioning as intellectually distinctive | Style: Surreal, hand-drawn, black-and-white line art | License: Free intro pack (11+ drawings) for personal and commercial use; attribution required for free; premium subscription unlocks full library

Absurd Design rejects the clean colorful SaaS illustration aesthetic entirely in favor of whimsical, surreal, intentionally imperfect black-and-white line drawings. The style feels editorial and intellectual: like illustrations from a philosophy book or a New Yorker article rather than a SaaS landing page.

What makes Absurd Design the right pick for specific brands: distinctiveness. If your product positions around creativity, deep thinking, or differentiation from typical SaaS, Absurd Design instantly signals "we are not like the other tools." The single biggest risk in choosing Absurd Design is choosing it wrong; for standard B2B SaaS, it reads as confusing rather than distinctive.

Where it falls short: extremely opinionated style. For most SaaS products, Absurd Design is the wrong choice. The free intro pack is small (11+ drawings); meaningful use requires the premium subscription.

How to actually pick an illustration library in 2026

Decision framework based on your product context:

If you are building a standard B2B SaaS landing page on a tight timeline: start with unDraw for speed plus the brand-color match feature. Customize the accent color, ship it, move on. Total time: 30 minutes per illustration.

If you are launching an indie SaaS or content product where differentiation matters: start with Lukasz Adam Illustrations or Open Peeps for character work. Hand-drawn aesthetics differentiate from the unDraw-saturated SaaS landing page space without alienating mainstream buyers.

If you are designing a developer tool or infrastructure SaaS: start with ManyPixels isometric for system visualizations. Pair with simple flat illustrations from unDraw for non-systems contexts.

If you are designing for product UI states (empty states, errors, 404s): start with Charco for the focused UI-state pack. For variations beyond Charco's 16 illustrations, extend with unDraw or PixelTrue for specific state contexts.

If you are designing premium SaaS marketing pages where polish matters more than time: start with DrawKit free tier or Shapefest for 3D elements. Both produce more polished output than unDraw at the cost of attribution requirements on the free tier.

If your brand has space for editorial distinctiveness: consider Absurd Design, but only for products where intellectual or creative positioning is core to brand strategy. For standard B2B SaaS, the wrong choice.

If your team page or onboarding needs diverse human representation: Open Peeps for CC0 hand-drawn diversity, or Humaaans if you can accept the CC BY 4.0 attribution. Both ship modular character systems rather than fixed characters.

The most common illustration mistake in 2026 is mixing libraries within one project. Three illustrations from unDraw, two from Storyset, and a Humaaans character on the same landing page produces visible style inconsistency that hurts the design more than fewer illustrations would. Pick one library per project; the rule applies across all 12 libraries above.

What changed in 2025-2026 that matters

Three shifts in the SaaS illustration landscape worth understanding:

Product screenshots replaced illustrations in hero sections. The 2024-2025 consensus shifted toward "show the actual product, not a cartoon" for SaaS hero sections. Illustrations now live in supporting roles: empty states, feature explainers further down the page, onboarding flows, and marketing pages where the screenshot does not exist yet. Treating illustrations as the primary hero visual in 2026 reads as outdated.

AI illustration generation became a quality concern. Premium illustration libraries (GetIllustrations, others) explicitly market "hand-crafted, no AI" as a quality differentiator in 2026. The AI illustration tools (Recraft, Midjourney, Adobe Firefly) produce viable illustrations on demand, but inconsistency across a set and licensing uncertainty (AI training data legal questions) make AI-generated illustrations risky for production design system use. Hand-crafted free libraries remain the safer choice for cohesive brand work.

The "one library per project" rule became consensus. Mixing illustration styles produces visual inconsistency that competing illustration libraries explicitly warn against in their own documentation. The 2026 best practice is committing to one library (or one collection within a multi-style library like Blush) per project and customizing within that constraint rather than mixing across libraries.

Frequently asked questions

What is the best free illustration pack for SaaS in 2026?

unDraw remains the most-used free illustration library for SaaS in 2026 because of its open license (no attribution required), one-click brand color matching, and 500+ illustration breadth across SaaS-relevant topics. For products where visual differentiation matters more than speed, Lukasz Adam Illustrations or Open Peeps offer warmer hand-drawn alternatives. For technical SaaS visualizing systems, ManyPixels isometric is the strongest free isometric library. The "best" depends on which aesthetic fits your brand positioning, not on which library has the most illustrations.

Are free illustration packs safe to use for commercial projects?

Yes, with license verification per library. unDraw (open license, no attribution), Open Peeps (CC0), PixelTrue (MIT), Lukasz Adam free pack, and Charco all permit commercial use without attribution. Storyset, DrawKit free, Humaaans, and Shapefest free tiers require attribution; their paid tiers remove this. Always verify the specific license on each library's distribution page before commercial deployment. For agency and client work where attribution is unacceptable, default to CC0 / MIT / no-attribution libraries.

Should SaaS landing pages still use illustrations in 2026?

Yes, but in supporting roles rather than as primary hero visuals. The 2024-2025 design consensus shifted toward product screenshots and micro-demos in SaaS hero sections because they show what the tool does rather than what it feels like. Illustrations remain valuable for empty states, feature explainers further down the page, onboarding flows, marketing pages where the screenshot does not exist yet, and brand-storytelling contexts. Treating illustrations as the primary landing page visual in 2026 reads as outdated; treating them as supporting visuals throughout the product remains effective.

Can I mix different illustration libraries in one project?

The 2026 best practice is no. Mixing illustration styles from multiple libraries produces visual inconsistency that hurts the design more than fewer illustrations would. The rule competing illustration libraries explicitly publish in their own documentation: pick one library (or one collection within a multi-style platform like Blush) per project. Customize colors and details within the chosen library rather than reaching for a different library when one feels limiting. If you genuinely need range a single library cannot provide, the answer is custom illustration commissioning, not library mixing.

What is the difference between unDraw and Storyset?

unDraw ships 500+ minimalist single-accent-color SVG illustrations under an open license with no attribution required. Storyset ships flat illustrations with multi-color customization, character variants, and animated Lottie variants under a free-with-attribution license (paid Premium removes attribution). unDraw is faster and licensing-friction-free; Storyset is more visually capable but requires either attribution or a paid plan. For most SaaS work, unDraw is the default; for marketing pages needing animation or richer color palettes, Storyset wins.

Are AI-generated illustrations good enough for SaaS production?

For one-off exploration and rapid prototyping, yes. For production design system use across a SaaS product, the 2026 consensus is no: AI-generated illustrations have inconsistency across a set, raise licensing questions about training data, and lack the deliberate craft that hand-illustrated libraries provide. Premium illustration libraries explicitly market "hand-crafted, no AI" as a quality differentiator in 2026 because design system buyers value the consistency. For cohesive brand work, free hand-crafted libraries (unDraw, Humaaans, Lukasz Adam) remain the safer choice over AI generation.

What illustration style works best for B2B enterprise SaaS?

Clean flat with single accent color (unDraw, Storyset) or polished flat (DrawKit) for general use; isometric (ManyPixels) for technical visualization; 3D (Shapefest) for premium marketing visuals. Avoid Absurd Design and very hand-drawn styles (Open Peeps, Lukasz Adam) for enterprise B2B because they read as too casual for senior enterprise buyers. The pattern: enterprise buyers expect visual polish that signals "this product is professionally maintained"; casual illustration aesthetics undermine that signal regardless of how good the actual product is.

What is the most overused free illustration in 2026?

unDraw's "Working from home" / laptop character / video call illustrations are the most-overexposed free illustrations in 2026, appearing on thousands of SaaS landing pages since 2020-2022. Using them as-is signals "I used the free pack everyone uses." The workaround is customizing the accent color to your brand, cropping or modifying the illustration meaningfully, or choosing an alternative library entirely. The same overexposure tax applies to SALY 3D illustrations and the most-downloaded Humaaans default poses.

Where to go from here

Pick one library from the list above and use it for one project this week. Most designers research illustration libraries for hours and never commit to one. The 2026 free illustration stack is mature enough that the library choice matters less than the discipline of sticking with it across the project. Customize the accent color, modify the illustrations beyond defaults, and ship.

For most SaaS work in 2026, the default recommendation is unDraw for speed and licensing-friction-free commercial use. For products where differentiation matters more than speed, choose Lukasz Adam, Open Peeps, or ManyPixels isometric based on style fit. For premium marketing pages, DrawKit or Shapefest. Whatever you pick, commit to it across the project: visual consistency from one library beats visual range from mixing libraries.
