Cella

Open source control plane that turns a manifest into a running, isolated sandbox for AI agents and code execution.

Servicefreeglobal

Cella is a free, open-source control plane that turns a declarative manifest into a running, isolated sandbox for AI agents or code execution, on Kubernetes, Podman, or a native runtime. It handles exec, terminal access, file transfer, and a virtual desktop, keeps secrets out of the sandbox itself via an egress gateway, and is the same control plane its maker runs its own hosted sandbox platform on.
