Open Builder is an open-source workspace for generating, editing, and previewing web apps with AI. Bring your own model provider, work in the browser or desktop app, and export your project when it is ready.
Use the Web app or run it locally with Node.js 24 and pnpm 11:
git clone https://github.com/Amery2010/open-builder.git
cd open-builder
pnpm install
pnpm dev
Open localhost:5173, configure your API type, endpoint, model, and credentials in Settings, then describe what you want to build.
For desktop development, install Rust and the Tauri prerequisites, then run:
pnpm tauri:dev
See the user guide for model configuration, Local CLI setup, and project workflows.
| Capability | Web | Desktop | Mobile (experimental) |
|---|---|---|---|
| API models, project editing, preview | Yes | Yes | Yes |
| Remote HTTPS MCP | Yes | Yes | Yes |
| Local CLI, stdio MCP, Skill scripts | No | Yes, subject to permissions | No |
| Project export | ZIP | ZIP or a new directory | ZIP |
No Open Builder backend is required. History and settings are stored locally; model requests and tool calls use the services you configure, and previews use Sandpack. Web endpoints must allow browser CORS. Local CLI mode still uses the CLI's configured model service.

Build the Web app and serve dist/ with a static host:
pnpm build
Or use the container image:
docker run --rm -p 8080:8080 ghcr.io/amery2010/open-builder:latest
Open localhost:8080. The container serves the Web app; native desktop capabilities require the Tauri app.
For Vercel, Cloudflare, or Netlify, use pnpm build and output directory dist. Repository automation is defined in the Pages and release workflows.
For portable Skills, the standalone CLI and local MCP setup, see the headless guide.
The application uses React 19, TypeScript 6, Vite 8, Tailwind CSS 4, Zustand, Sandpack, and Tauri 2.
pnpm test runs frontend and Rust tests, so it requires Rust and the Tauri platform prerequisites. Use pnpm test:frontend for Web-only changes or pnpm test:rust for native tests. These tests do not exercise installer downloads, signing, or notarization; release packaging has separate retries, tool caches, and macOS signing preflight.
pnpm typecheck
pnpm lint
pnpm format:check
pnpm test
pnpm build
See CONTRIBUTING.md for the complete validation and release workflow. The user guide also covers native build commands.
