Deploy pluto

Deploy and Host pluto on Railway

Pluto is a self-contained data notebook for TypeScript and SQL. One binary bundles a TypeScript/JavaScript kernel, Postgres, SQLite, DuckDB and Polars, with a browser UI that has type-aware completions. Query CSV and Parquet files, mix SQL with code, render tables and HTML, and drive it from AI agents over MCP.

About Hosting pluto

Pluto ships as a single Docker image (ghcr.io/junkiez/pluto) with no external services: every database engine is embedded and stores its data next to the notebook files. Hosting it needs one service with a persistent volume mounted at /data, where notebooks, Postgres/SQLite/DuckDB databases and uploaded files live. Set PLUTO_PASS to protect the instance, since notebook cells run arbitrary code. Railway provides PORT automatically. Redeploys keep all notebooks and data on the volume.

Common Use Cases

• Exploring CSV, Parquet and JSON data with DuckDB, Polars and SQL, mixing queries with TypeScript in one notebook
• Hosted scratchpad for prototyping data pipelines, API calls and quick reports with tables and HTML output
• Giving AI agents (Claude, Cursor, etc.) a sandboxed place to run code and SQL through the built-in MCP endpoint

Dependencies for pluto Hosting

• A Railway volume mounted at /data (notebooks and databases)
• PLUTO_PASS variable (password for the UI and MCP)
