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.

# Save one prepared repo baseline
$ sys9 run snap fork --from-box app-base
Preparing snap ...
OK: Forked snap s8p4fork1.

# Open parallel boxes from the same snap
$ sys9 run box create agent-fix-login --snap s8p4fork1
OK: Created box agent-fix-login
$ sys9 run box create agent-write-tests --snap s8p4fork1
OK: Created box agent-write-tests
$ sys9 run box create agent-repro-bug --snap s8p4fork1
OK: Created box agent-repro-bug

# Run work inside one branch
$ sys9 run box exec agent-write-tests npm test -- login
PASS login.spec.ts

Full Environment

Save code, installed packages, and application files from the root filesystem. Fork Volumes separately; each branch starts fresh processes.

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.
