Full Environment
Save code, installed packages, and application files from the root filesystem. Fork Volumes separately; each branch starts fresh processes.
Forkable Sandbox
for Agents.
Fork & Scale your agent's entire environment. Prepare one baseline, open parallel boxes across your org, and test changes in isolated branches.
CLI-First
Ship from your terminal.

Fork & Scale
Fork a running box with a brief pause, then open parallel boxes from the ready snap for agent tasks, test shards, or database branches.
Serverless Runtime
Boxes wake when used, sleep when idle, and the platform adds runtime capacity as your org fans out work.
Data on Its Own Disk
Mount persistent Volumes beside the environment. Fork the tools without the session data, or fork the data alone and restore it into a new box.
Warm First Run
Record a workload once on a baseline. Every box forked from it starts that workload with the files it needs already in place.
Keys Stay Outside
Agents work with a placeholder. The real API key is added on the way out, and only for the hosts you allow.
