What is it?

Srcbook is a notebook for writing and running TypeScript code. It runs as a local CLI application that serves a web interface, so notebooks and execution stay on your own machine. Notebooks are stored as markdown files with the .src.md extension, which makes them readable and portable outside the app.

Beyond running code cells, Srcbook supports Mermaid diagrams for annotating notebooks and AI features for exploring and iterating on ideas. AI usage requires your own API key, and the project recommends Anthropic with claude-3-5-sonnet-latest. It can also be run in Docker, and it is installed and started through npx or a global npm install.

The project is Apache-2.0 licensed and the maintainers note that it is no longer under active development.
