Before you install
- Run it in a separate browser profile without your logged-in accounts.
- Pin the version you reviewed instead of always installing the latest release.
- Read the tool list or scripts before the first run, and keep approval prompts on for actions that write, send or delete.
- Maintained by platonai on GitHub, 1,172 stars and 154 forks. Popularity is not proof of safety.
- Last code change: Nov 1, 2026.
