Open-source alternatives to Figma

Figma is a browser-based design tool for UI/UX design, prototyping, and design system management. Its defining feature is real-time collaborative editing — multiple designers editing the same file simultaneously with live cursors. Teams use it for product design workflows, from wireframing to high-fidelity mockups to interactive prototypes that developers can inspect for CSS and measurements.

Penpot: The open-source design tool for design and code collaboration

penpot/penpot Updated 2026-05-05

Comparison notes

Penpot is the only OSS alternative targeting Figma's UI design use case directly, with vector editing, component libraries, and an export-compatible file format. It supports collaborative editing in its cloud version and is self-hostable. The main gaps: Penpot's community plugin ecosystem is much smaller than Figma's, and its prototyping capabilities (interactions, smart animate) are less mature. Figma's Dev Mode (developer inspect with CSS exports) and Variable Libraries for design tokens have partial Penpot equivalents but require more manual workflow. Excalidraw covers whiteboarding but not production UI design.

Migration tips

  • Penpot supports importing Figma files via the Figma import feature — test your most complex files first for fidelity
  • Export Figma assets (icons, images) as SVG or PNG before migration as a backup
  • Recreate Figma component libraries as Penpot component libraries — linked components do not auto-convert
  • Update your developer handoff workflow — Penpot's inspect panel differs from Figma Dev Mode
  • Notify all team members and external collaborators (clients, developers) of the new file location

FAQ

Can I fully replace Figma with an OSS tool?

Feature parity varies. Most OSS alternatives cover 70-90% of core workflows, but may lack polish, integrations, or specialized features. Pilot the alternative with a subset of your team before fully committing.

What's the cost of self-hosting?

Plan for ~$5-50/month in VPS costs (DigitalOcean, Hetzner, etc.) plus 2-8 hours/month in maintenance. For a team of 20+, self-hosting usually breaks even against SaaS pricing within 6-12 months.

Which alternative should I pick?

Sort by GitHub stars (a proxy for community health), check the last-pushed date (avoid unmaintained projects), and read recent issues to gauge responsiveness.
