​​Livebook is a web application for writing interactive and collaborative code notebooks for #elixir, built with Phoenix LiveView. Inspired by Jupyter and Deepnote.

It features:
- Code notebooks with Markdown support and Elixir cells where code is evaluated on demand.
- Shareable: notebooks are stored in the .livemd format, which is a subset of Markdown with annotations and KaTex for mathematical formulas. This means your notebooks can be saved, easily shared, and play well with version control.
- Interactive widgets via Kino: manipulate Vega-Lite charts, tables, and more.
- Rich code editor through Monaco: with support for autocompletion, inline documentation, code formatting, etc.
- Reproducible: Livebook ensures your code runs in a predictable order, all the way down to package management. It also tracks your notebook state, annotating which parts are stale.
- Custom runtimes: when executing Elixir code, you can either start a fresh Elixir instance, connect to an existing node, or run it inside an existing Elixir project, with access to all of its modules and dependencies. This means Livebook can be a great tool to provide live documentation for existing projects.
- Persistence: persist your notebooks to disk or any S3-compatible cloud storage.
- Collaboration: multiple users can work on the same notebook at once. It works out-of-the-box either in single-node or multi-node deployments - without a need for additional tooling.
