UI Design Editor: free MIT design canvas for your own AI assistant

The offer

Users in India can open UI Design Editor free in a browser without signing up to edit mockups, images and HTML designs, then export an editable HTML copy. Its MIT-licensed source can also be self-hosted with Node.js 24+, while AI editing requires your own assistant and a browser with supported WebMCP site tools; no paid AI subscription or model credits are included. Shared projects and media are saved on the server, anyone with a Space or project link can read and edit every project in that Space, and connected AI providers may process your designs.

Who can claim it

• Free browser editor with no signup and no published India restriction.
• AI site-tool editing requires your own supported AI assistant and browser.
• Optional self-hosting requires Node.js 24 or newer and your own server.

How to claim it

1. Open the official editor to create a Space.
2. Add text, shapes, HTML designs or a screenshot to the canvas.
3. For AI edits, select Connect AI and use its prompt with your own supported assistant while the editor remains open.
4. Use Copy HTML to save an editable HTML file; keep your Space link if you want to return to shared projects.

Good to know

No timed trial or subscription is stated for the editor. Optional AI-assistant accounts, model use and self-hosting have their own costs and terms.

The current source archive is MIT-licensed; no tagged release is published. Space projects and media are stored on the server, not only on your device. Any Space or project link grants read/edit access to every project in that Space. Connected AI providers can process designs; hosting providers process connection details including IP addresses. HTML exports keep their own local copy.
