Best Open Source Alternatives to Figma in 2026
Figma Gets More Expensive Every Year
Figma's pricing has climbed steadily since Adobe's acquisition attempt put the spotlight on its market dominance. Here's what you're paying in 2026:
| Plan | Cost (per editor/month) | Notes |
|---|---|---|
| Starter | Free | 3 Figma files, 3 FigJam boards |
| Professional | $15/month ($12 annual) | Unlimited files, team libraries, shared fonts |
| Organization | $45/month | Annual only, org-wide design systems, SSO |
| Enterprise | $75/month | Annual only, dedicated support, advanced security |
For a 10-person design team on Professional (annual), that's $1,440/year. Organization pricing pushes that to $5,400/year. And those are just editor seats — Figma also charges $5/month for full seats (previously free viewers who need edit access) and $25/month for dev mode seats on Organization plans.
The free Starter plan caps you at 3 design files. For any real team work, you're paying.
Open source alternatives have matured significantly. Penpot now supports CSS Grid layouts, native design tokens, and real-time collaboration. Lunacy ships a full-featured free design tool with built-in AI and asset libraries. Here are the best options available right now.
TL;DR
Penpot is the most mature open source Figma alternative with real-time collaboration, CSS-native design output, components, variants, and design tokens. It's free to use on their cloud or self-hostable. For teams that want a polished desktop app with built-in assets and AI features, Lunacy is free for core design work (though not fully open source). If your workflow centers on prototyping and user testing rather than visual design, Quant-UX fills a gap that Figma itself handles poorly.
Key Takeaways
- Penpot (35K+ GitHub stars) is the strongest open source Figma alternative — SVG-native, CSS Grid layout, components with variants, design tokens following W3C standards, and a plugin system.
- Lunacy is free for core design features with built-in Icons8 assets, AI tools, and cross-platform desktop + web apps. Not open source, but the free tier is generous.
- Quant-UX (2.4K+ stars) uniquely combines prototyping with built-in user testing, heatmaps, and analytics — something Figma doesn't offer natively.
- Akira is an early-stage native Linux design app. Promising concept, but alpha-quality and not ready for production work.
- Plasmic is a visual builder for React, not a traditional design tool. It bridges design and code but targets developers more than designers.
- No open source tool fully matches Figma's auto-layout polish, plugin ecosystem, or dev handoff experience yet. Penpot is closest and closing the gap fast.

Penpot — Best Overall Figma Alternative
Penpot is the tool that most directly competes with Figma. It's a browser-based design and prototyping platform built by Kaleidos, with real-time collaboration, a component system, and — critically — design output expressed natively as CSS, SVG, and HTML rather than proprietary formats.
What It Does Well
CSS-native design. This is Penpot's defining feature. When you create a layout in Penpot, you're building with actual CSS Flex and CSS Grid. Developers inspecting your designs see real CSS properties, not approximations. The Penpot 2.0 release introduced CSS Grid Layout as a first-class feature, making it the first design tool to express grid layouts the way browsers actually render them.
Components and Variants. Penpot 2.10 introduced Variants, letting you group related component states (e.g., button sizes, hover states, active/disabled) into a single organized unit. Combined with the existing component system, you can build scalable design systems.
Design Tokens (W3C standard). Penpot is the first design tool to implement native design tokens following the W3C Design Tokens specification. Tokens are stored in the standardized format, so there's no third-party plugin dependency to export them. This is a genuine advantage over Figma, where design tokens require plugins like Tokens Studio.
Plugin system. PenpotHub hosts a growing library of community plugins and templates. If Penpot doesn't do something out of the box, you can extend it — similar to Figma's plugin ecosystem, though significantly smaller.
Deployment flexibility. Use Penpot's free cloud instance at design.penpot.app, or self-host with Docker. The self-hosted deployment gives you full control over your design data.
Feature Parity with Figma
| Feature | Figma | Penpot |
|---|---|---|
| Auto-layout (Flex) | Yes | Yes |
| Grid layout | CSS Grid via auto-layout | Native CSS Grid |
| Components | Yes | Yes (with Variants) |
| Design tokens | Plugin-dependent | Native (W3C standard) |
| Prototyping | Advanced | Basic-intermediate |
| Dev handoff/inspect | Dev Mode ($25/seat) | Free (CSS/SVG native) |
| Plugins | 2,000+ marketplace | Growing (PenpotHub) |
| Real-time collaboration | Excellent | Good |
| Offline support | Limited | No |
| Design system libraries | Mature | Growing |
Limitations
Penpot's prototyping capabilities are functional but less polished than Figma's. Advanced interactions, smart animate transitions, and complex prototype flows don't match Figma's depth.
Performance can lag on very large files with many artboards. Figma's WebGL rendering engine is highly optimized; Penpot's SVG-based rendering handles most projects well but struggles with massive design systems.
The plugin ecosystem is small compared to Figma's thousands of community plugins. Penpot's plugin gallery is growing but can't match that breadth yet.
Best for: Teams that want an open source, self-hostable design tool with real CSS output and no per-seat licensing. Especially strong for design-developer collaboration.
Lunacy — Best Free Desktop Design Tool
Lunacy, built by Icons8, is a free cross-platform design tool that runs natively on Windows, macOS, and Linux, with a web version available at lunacyapp.com. It's not open source — the core application is proprietary — but it deserves inclusion because its free tier is more capable than Figma's Starter plan and it competes directly on features.
What It Does Well
Built-in asset libraries. Lunacy ships with access to Icons8's library of icons, illustrations, and photos directly inside the editor. No hunting for assets in separate browser tabs. Free usage requires attribution; paid Icons8 subscriptions ($4.99/seat Professional) remove that requirement and unlock SVG and high-resolution formats.
AI integration. Lunacy includes LLM integration supporting Claude, Gemini, OpenAI, and Grok — no API keys required on the free tier. AI features cover content generation, auto-layout suggestions, and design assistance.
Platform selection. Choose your target platform (iOS, Android, web), and Lunacy automatically provides matching UI components, speeding up platform-specific design work.
Recent 2026 additions. Scroll overflow for prototypes, multiple prototype flows, an override inspector for component overrides, vertical text trimming, connectors for flow diagrams, and a feature-complete web version (deployable in closed environments for sensitive data).
Limitations
Lunacy's free plan has meaningful collaboration constraints: 3 team members, 10 cloud documents, and a maximum of 3 editors per document. The Professional plan ($4.99/seat) removes these limits.
The asset library is Lunacy's biggest draw, but the free icons and illustrations require attribution. Clean, attribution-free exports need a paid Icons8 subscription on top of any Lunacy plan.
Since it's proprietary software, you can't audit the code, fork it, or self-host the core application (enterprise web self-hosting is $49.99/seat). You're dependent on Icons8's continued goodwill for the free tier.
Best for: Solo designers and small teams who want a capable, free desktop design tool with built-in assets. A pragmatic choice when open source isn't a hard requirement.
Quant-UX — Best for Prototyping and User Testing
Quant-UX occupies a different niche than Penpot or Lunacy. It's not trying to replace Figma's visual design capabilities. Instead, it focuses on interactive prototyping combined with built-in user testing and analytics — a workflow that typically requires Figma plus a separate tool like Maze or UserTesting.
What It Does Well
Prototyping with built-in testing. Create interactive prototypes with animations, logic flows, form validation, and conditional navigation. Run user tests directly inside the same tool, with screen recordings capturing exactly how testers interact with your prototype.
Analytics and heatmaps. Quant-UX generates heatmaps showing where users click, calculates task success rates, and tracks completion paths. A/B testing lets you compare design variants with real user data — functionality Figma doesn't offer natively.
Figma import. A Figma Import Plugin lets you bring existing Figma designs into Quant-UX, add interactions and logic, and start testing without rebuilding screens from scratch.
Design system basics. Design tokens, components, and master screens let you maintain consistency across prototype screens. It's not as sophisticated as Penpot's or Figma's component systems, but it covers the essentials.
Low-code output. Quant-UX can convert prototypes into production-ready code, bridging the gap between prototype and implementation.
Self-Hosting
Quant-UX can be self-hosted via Docker. The deployment requires:
- Quant-UX frontend — the web application
- Quant-UX backend — API server
- MongoDB — database
Community-maintained Docker Compose configurations make deployment straightforward. The hosted version at quant-ux.com is free to use.
Limitations
Quant-UX is not a visual design tool. You won't create polished UI mockups here — the widget set is functional but basic compared to Figma's vector editing capabilities. The intended workflow is to design in Figma (or Penpot), import into Quant-UX, and add interactivity and testing.
The community is small (2.4K GitHub stars). Documentation exists but isn't comprehensive. You'll likely reference the source code and community forums for advanced features.
Best for: UX teams and product managers who need prototyping with integrated user testing and analytics. Pairs well with Penpot or Figma for visual design.
Akira — Native Linux Design Tool (Early Stage)
Akira aims to be a native Linux design application built with Vala and GTK, targeting web designers and graphic designers who use Linux as their primary operating system. The project's goal is to provide a professional design tool that runs natively on Linux without relying on Electron or browser-based rendering.
Current State
Akira is in alpha. Available via Flatpak or compiled from source, but not ready for production work. Basic shape tools, layers, and canvas manipulation exist, but components, auto-layout, prototyping, and collaboration are not yet implemented.
The Linux design tool gap is real — no native application matches the performance of Sketch on macOS. Akira is attempting to fill that gap, with community-driven development supported through Liberapay and Patreon. Progress is slow but ongoing.
Limitations
Akira lacks components, auto-layout, prototyping, collaboration, plugins, design tokens, and most features expected from a modern design tool. It's a project to follow, not a tool to adopt today.
Best for: Linux users who want to support and contribute to a native design tool for the platform. Not suitable for professional use yet.
Plasmic — Visual Builder for React Teams
Plasmic is not a traditional design tool. It's a visual page builder and headless CMS that generates real React code. Designers drag and drop components in a visual editor; developers register their React components for use in the visual builder. The output is production code, not a design file.
What It Does Well
Code generation, not handoff. Plasmic's output is actual React code integrated with your codebase. There's no "design to development handoff" because the design is the code.
Component registration. Developers register existing React components in Plasmic's visual editor. Designers use those real components (with actual props and behavior) instead of abstract representations, eliminating the fidelity gap between design and implementation.
Data sources and headless CMS. Plasmic connects to Airtable, PostgreSQL, Shopify, and arbitrary REST/GraphQL APIs. Non-technical team members can build and publish data-driven pages using registered components without touching code.
Self-Hosting
Plasmic's visual editor runs as a hosted service. The open source components (MIT-licensed) handle code generation and framework integration. The platform (AGPL-licensed) can be self-hosted, but most teams use Plasmic's cloud editor.
Limitations
Plasmic is not for creating design mockups or exploring visual concepts. It's for turning finalized designs into production React applications. The React dependency is absolute — if your stack doesn't use React, Plasmic isn't an option.
Best for: React development teams that want to let designers and content editors build production pages visually using real components. Not a Figma replacement — a Figma complement.
Feature Parity Reality Check
Here's an honest assessment of where open source tools stand against Figma's core features:
| Feature | Figma | Best OSS Option | Gap |
|---|---|---|---|
| Vector editing | Excellent | Penpot (Good) | Small |
| Auto-layout | Excellent | Penpot Flex+Grid (Good) | Small |
| Components/Variants | Excellent | Penpot (Good) | Small |
| Design tokens | Plugin-dependent | Penpot native (Better) | Penpot leads |
| Prototyping | Excellent | Quant-UX (Good, different) | Medium |
| Dev handoff/inspect | Dev Mode (paid) | Penpot CSS native (Good) | Penpot leads |
| Plugin ecosystem | 2,000+ | Penpot (small but growing) | Large |
| Performance (large files) | Excellent | Penpot (Adequate) | Medium |
| Real-time collaboration | Excellent | Penpot (Good) | Small |
| FigJam (whiteboarding) | Included | No equivalent | Large |
| AI features | Figma AI | Lunacy LLM (Good) | Medium |
Penpot actually leads Figma in two areas: native design tokens (W3C standard vs. plugin-dependent) and dev inspect (free CSS output vs. $25/seat Dev Mode). The largest gaps remain in the plugin ecosystem, advanced prototyping, and performance optimization.
How to Choose
"I need the closest thing to Figma, open source" — Penpot. It has components, variants, design tokens, CSS Grid, Flex layout, real-time collaboration, and a plugin system. Self-host it or use the free cloud.
"I need a free desktop design tool with built-in assets" — Lunacy. Not open source, but the free tier is more capable than Figma's Starter plan. Cross-platform native apps perform well.
"I need prototyping with user testing" — Quant-UX. Design in Penpot or Figma, import into Quant-UX, add interactions, and run user tests with built-in analytics.
"I need designers to build production React pages" — Plasmic. It's a visual builder, not a design tool. Designers use real React components to build real pages.
"I'm on Linux and want a native app" — Watch Akira, but use Penpot (browser-based) today. Akira isn't production-ready.
Cost Comparison: Figma vs Open Source
For a 10-person design team, here's what you're actually paying.
Figma (10 Editors)
| Plan | Annual Cost |
|---|---|
| Professional ($12/editor/month annual) | $1,440 |
| Organization ($45/editor/month) | $5,400 |
| Enterprise ($75/editor/month) | $9,000 |
| + Dev Mode (5 devs, $25/month Org) | +$1,500 |
Open Source / Free (10 Users)
| Option | Annual Cost |
|---|---|
| Penpot Cloud (free) | $0 |
| Penpot self-hosted (VPS) | $240-$480 |
| Lunacy free tier | $0 |
| Lunacy Professional (10 seats) | $599/year |
| Quant-UX cloud (free) | $0 |
Penpot's free cloud tier has no per-seat pricing. There are no editor limits, no file limits on the free plan. Self-hosting costs only the infrastructure — a modest VPS handles a 10-person team comfortably.
