Open-source Figma alternative.

What Figma is

Figma is a hosted, collaborative interface design tool: a browser-based vector canvas with real-time multiplayer editing, prototyping, a large plugin and component ecosystem, and a designer-to-developer handoff. It is the default for hands-on UI design, and it has added AI features of its own.

It is closed-source and runs in the vendor cloud, billed per editor seat. Open Design is a different shape: a local-first, open-source design agent you point your own coding agent at — the two overlap on producing interfaces, not on real-time canvas editing.

• Vendor: Figma — hosted SaaS
• Pricing: per-editor seats
• Primary output: cloud design documents

Why teams look for a Figma alternative

Teams start looking past Figma when they want design to be files they own, generated and iterated by the agent they already use, rather than documents living in a vendor cloud.

• Own the files: Design should be version-controlled artifacts in your repo, not cloud documents you only reach through one app.
• Open source: Apache-2.0 and self-hostable: fork it, rebrand it for your studio, or embed it in CI — not a closed per-seat SaaS.
• Agent-driven: Generate and iterate design with the coding agent you already use, instead of drawing every frame by hand.
• Portable brand: One DESIGN.md encodes a brand every skill respects, versioned with your code.

Local-first + BYOK, explained

Open Design runs a desktop app, a local daemon, and Markdown skill and design-system catalogs on your machine. Your designs are files, not cloud documents, and your brand lives in your repo as a portable DESIGN.md file every skill respects.

You bring your own agent key. Credentials stay in local config or environment variables — Open Design never proxies them — and the API spend bills directly to you.

Open Design vs Figma, feature by feature

Where Figma wins: hands-on vector editing, a real-time multiplayer canvas, and a deep, mature plugin and component ecosystem. If that hands-on canvas is the job, Figma is hard to beat — Open Design is design-first and agent-driven instead.

Who should pick which

Pick Figma if:

• You want hands-on vector editing and a real-time multiplayer canvas.
• Your team lives in a mature plugin and component ecosystem.
• You prefer a hosted designer-to-developer handoff over files.

Pick Open Design if:

• You want design artifacts and a brand as version-controlled files.
• You want BYOK with your existing coding agent.
• You want open source you can fork, rebrand, embed in CLI, or self-host.
• You want one DESIGN.md per brand that every skill respects.

Moving a design from Figma into Open Design

There is no automatic import from Figma today; start design-first with a one-time brand-extraction run.

1. Install Open Design from the quickstart.
2. Open the web UI and point your agent at a Figma frame or screenshot you like.
3. Ask the agent to extract the brand into a DESIGN.md file.
4. Pick a skill and render it against your new brand.

From then on, every skill renders in your brand without re-prompting — and the files stay in your repo.

FAQ

1. 01 Is Open Design a drop-in replacement for Figma? +

   No. Figma is a hands-on collaborative canvas; Open Design is an agent-driven, local-first design layer. They overlap on producing interfaces, not on real-time canvas editing.

2. 02 Can I still use Figma alongside Open Design? +

   Yes. Many teams design in Figma and use Open Design to generate and iterate from a portable brand; migration is manual today.

3. 03 Which agent does Open Design use? +

   Your choice — BYOK with Claude Code, Codex, Cursor, Gemini, OpenCode, or Qwen. Credentials are never proxied through us.

4. 04 Is Open Design really open source? +

   Yes. It lives at github.com/nexu-io/open-design under Apache-2.0 and is self-hostable.

5. 05 Is Open Design affiliated with Figma? +

   No. Open Design is an independent, open-source project. Figma is a trademark of its owner; this is an unaffiliated comparison.
