What is mngr?
A Unix-style CLI for running coding agents in parallel. One command launches an agent on your laptop, a Modal sandbox, or a Docker container. Same commands whether you run one agent or a hundred.
Which agents and hosts does it support?
Claude, Codex, OpenCode, or any agent you can launch from a shell. Hosts can be local, Modal, Docker, or anything else you can SSH into. Plugins let you add your own agent types, providers, and commands.
How fast is it?
It’s fast. Depending on your setup, agents can start and mngr list returns within a few seconds. There's no managed service in the middle. Just SSH, git, and tmux.
What does it cost?
The CLI is free and MIT-licensed. You pay for inference and the compute on whichever host you pick. Remote hosts auto-shutdown when agents go idle, so a Modal run typically costs a fraction of a cent in compute beyond inference.
How are agents isolated?
Each agent gets its own container, accessed over a unique local SSH key. You can block all outgoing internet with -b offline, restrict traffic to an IP allowlist, or layer on the provider's native isolation. If an agent does something reckless, the blast radius stops at the container.
How do I install it?
