Run a sandbox

Run a sandbox on your own computer and, linked to your account, it runs MCP servers such as a web browser for you wherever you talk to Kaja, even from a Telegram chat. Lending its power to others is optional. The command below starts an anonymous one that everyone shares; sign in for your own key.

docker run -d --name kaja-sandbox --restart unless-stopped --memory 4g --cpus 2 --shm-size 1g -v kaja-sandbox:/data subztep/kaja-sandbox
