Celesto: open-source platform gives AI agents their own cloud computer in secure microVM sandboxes
aniketmaurya · x · 2026-10-11
Developer aniketmaurya is building Celesto, a platform that gives AI agents a "real computer" to work on.
Key points:
- Agents run in secure microVM sandboxes; the platform observes behavior and helps improve from every run.
- Three entry points: a CLI (create/exec/SSH in three commands), a browser-use environment for web navigation, and human-in-the-loop control to take over and hand back.
- Persistent sessions keep files, browser logins, and workspace state across runs.
- Apache-2.0 open-source core for self-hosting, plus a managed cloud with per-usage billing; 400+ developers building so far.
