Celesto: open-source persistent microVM computers for AI agents, boots in 500ms
aniketmaurya · x · 2026-09-29
Highlighting a contrast between $518B in infrastructure spending and usage-based compute for agents, the author points to open-source project Celesto (1k stars on GitHub): it gives AI agents their own secure, persistent computer for running code, browsing the web, and using desktop apps.
- Each sandbox is a lightweight microVM, booting in about 500 ms
- Files and state persist across sessions
- Runs locally during development or on Celesto Cloud in production
- Ships with a Python API, OpenAPI spec, guest-agent, examples, and docs; fully self-hostable
The repo also bundles .claude/skills and .agents/skills directories for easy integration with mainstream agent frameworks.
