Before you install Celesto
AgenticMart scanned Celesto on Nov 5, 2026 with automated checks for hidden code, known-malicious packages, leaked secrets and vulnerable dependencies. The result covers one commit under our scan policy, so review what access you give it and check any advisories shown here.
What it can access
- An AI agent decides its own next steps and calls whatever tools you give it, so its risk depends on the access you grant.
- Based on its description and topics, it likely needs to control a web browser (visit sites, fill in and submit forms).
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 CelestoAI on GitHub, 1,119 stars and 92 forks. Popularity is not proof of safety.
- Last code change: Oct 31, 2026.
- Open-source license: Apache-2.0.
