Questions people ask
Do I need a Grain subscription for the agent?
No. Bring Claude Code, Codex or Cursor on your own plan. We never mark up tokens.
What happens if I stop paying?
Published artifacts stay published on the free tier. Everything is files you can export.
Is this just a hosted sandbox?
A sandbox is where code runs once. A workspace is where it stays, with a URL, a database and the people you share it with.
Windows and Linux?
Yes. The desktop app runs on macOS, Windows and Linux.
