Livebook is an open-source interactive notebook platform powered by Elixir for automating code and data workflows in a collaborative and reproducible way.

🚀 Overview

Livebook brings the interactive notebook experience to the Elixir ecosystem, similar to Jupyter notebooks but optimized for Elixir's concurrency and fault-tolerance. It allows users to write Markdown, execute Elixir code, visualize data, and build workflows in one place, replacing scattered scripts, manual steps, and outdated documentation.

The project solves the problem of non-reproducible code execution, lack of collaboration in data analysis, and slow prototyping by providing smart cells for common tasks like database queries, machine learning, and visualizations, all running in a predictable environment.

It's built for Elixir developers, data scientists, ML practitioners, and teams building internal tools, prototypes, or production apps. Created to leverage Elixir's strengths for interactive computing, sharing knowledge, debugging systems, and deploying apps effortlessly.

✨ Key Features

Interactive insights: Visualize data with VegaLite charts, tables, maps (MapLibre), diagrams (Mermaid), and math (KaTeX); add inputs for dynamic apps.
Smart cells: High-level abstractions for databases (PostgreSQL, MySQL, BigQuery), ML models (Hugging Face), Slack integrations, speeding up workflows.
Real-time collaboration: Multiple users edit notebooks simultaneously, perfect for teams.
Reproducible workflows: Sequential execution, dependency tracking, stale cell detection, package management.
Productive editor: Autocompletion, inline docs, formatting, shortcuts via CodeMirror.
Portable notebooks: Saved as .livemd Markdown files for Git, easy sharing.
Optional: Livebook Teams beta for managed hosting and SSO.
