Notebooks & datasets

Hosted marimo notebooks run free in the browser (Pyodide) or on per-minute cloud machines that stop when idle. Datasets accept csv, json, jsonl (agent traces auto-detected), parquet, sqlite .db files, images, and browser-playable video; binary formats stream from the CDN and table previews open in the Sheets editor. Machine rates include the platform margin — what /api/notebooks/pricing returns is what you pay.
