Environment ready. Secrets proxied. No timeout.

Built for developers

Everything you need to run secure, persistent sandboxes.

01

Open source & self-hostable

Run it on your own infrastructure. No vendor lock-in, full control over your execution environment.

02

Secure secrets

Built-in secret proxy keeps credentials safe. Your secrets never touch the sandbox directly.

03

Never times out

Hibernation and restore means your sandbox sleeps when idle and wakes instantly when needed.

04

Local first

Designed for both human developers and agentic workflows. Works the same locally and in production.
