Srcbook

Srcbook is an open-source, local-first development environment that blends a TypeScript notebook with an AI-assisted app builder, giving developers a flexible space to prototype, explore, and build full web applications with AI support and real execution. It runs locally through a CLI tool backed by Node.js, launching a web interface where users can write and execute TypeScript code interactively, visualize results, and iterate quickly on ideas without leaving the browser. Srcbook’s notebook component offers a structure similar to Jupyter or Livebook, but focused on the JavaScript/TypeScript ecosystem, letting developers intermix code, documentation, and visuals while executing code cells on demand. The AI app builder extends this by helping generate, modify, or fix code using configured AI models — with changes presented as editable diffs and the ability to accept or reject updates — enabling rapid prototyping of web UIs and backend logic.
