Penpot is the leading open-source alternative to Figma for interface design and prototyping. It appeals to teams that want modern design tooling without per-seat pricing or a proprietary file format. It is not a one-for-one replacement, though, and it pays to go in with clear eyes. Here are the strengths and weaknesses, honestly weighed, so you can decide whether it fits your team.
The pros
- Truly open source. Released under the Mozilla Public License with the code on GitHub. There are no license fees, no seat counts, and no vendor holding your work in a format only their tool can read. Large organizations can audit the code before approving it, which helps with security review.
- Built on web standards. Designs are SVG styled with CSS-like properties. Developers get real values in inspect mode instead of approximations, which narrows the design-to-code gap, and exported assets open in any editor.
- Layout that mirrors the web. Flex and CSS Grid layout follow the same rules browsers do, so responsive designs behave as expected when they are implemented. Designers end up thinking in the same terms front-end developers use, which shortens review cycles.
- Self-hostable and private. You can run Penpot behind your own firewall with Docker, which matters for agencies and companies that treat design work as confidential. Access stays inside your network and you decide who can register and view files.
- Real-time collaboration. Live multiplayer editing, comments, and shareable prototype links cover the day-to-day teamwork of most product teams. Guests can comment on shared links without needing an account.
- Free to start. Small teams can use the cloud free tier, and self-hosting removes user limits entirely, so there is no billing barrier to evaluating it properly.
The cons
- A smaller ecosystem. There are fewer plugins, templates, and community files than Figma. Some popular Figma plugins have no equivalent yet, so workflows built around them need to be redesigned.
- Simpler prototyping. Interactions cover the basics, but there is no equivalent to Figma’s Smart Animate, and no built-in whiteboard like FigJam. User-testing flows that lean on advanced animation will feel constrained.
- Performance on very large files. Big, complex files can feel slower than in Figma. Good file hygiene and splitting large libraries into smaller files help, but very heavy projects need discipline.
- A layout learning curve. If you expect Sketch or Figma auto-layout behavior, Penpot’s flex and grid model takes a day or two to internalize. The payoff is designs that map cleanly to CSS, but plan for some onboarding time.
- Self-hosting is your job. The Docker stack includes several services that need routine care, and updates, storage, and backups fall to you, unless you run it on a hosted server from OpenSysLab.
Who should use Penpot?
Design teams that value open standards, developer-heavy teams who want an honest handoff, startups avoiding per-seat pricing, and any organization that needs design files to stay on infrastructure it controls will benefit most. It also suits government and research groups whose procurement rules favor open software.
Who should look elsewhere?
Teams that depend on Figma-specific plugins, advanced motion prototyping, FigJam workshops, or enterprise workflows standardized around Figma should stay there. If your clients expect .fig deliverables or heavy round-tripping with Figma users, expect friction and plan for it.
The bottom line
Penpot is a rare open-source tool that competes on quality, not just price. Its gaps are real but narrow: ecosystem depth and prototyping polish. If those do not block you, it is a sound long-term choice. You can try it on a managed server via the hosted Penpot page on OpenSysLab.
