Livebook
Collaborative Elixir notebooks with live code execution, Mermaid diagrams, and TeX
Overview
Livebook is a real-time collaborative notebook application for Elixir that combines Markdown documentation, executable Elixir code cells, TeX math, and Mermaid diagrams in a single interface. Notebooks can be shared and co-edited live, and Livebook ships with Smart Cells that auto-generate boilerplate for database connections, charts, and ML model deployment. It deploys easily via a single Docker image or the Elixir Mix toolchain, and includes a managed hosting option on Hugging Face.
Where it falls short of Notion
- Exclusively supports Elixir; no Python, R, or Julia kernels unlike Jupyter
- Not a general-purpose note-taking tool — unsuitable as a Notion replacement for non-developers
- No persistent database-style pages, kanban boards, or project management views
- Community plugin ecosystem is smaller than Jupyter's
We list the gaps honestly so you can decide if the trade-off is worth owning your data.
