I use a central server behind a vpn and oauth that gives me access to my "farm". A product I wrote to manage fleets of docker containers that's now being used to manage fleets of docker containers running a tty wrapper I also wrote to send everything over. The backend to this is go+htmx+websockets. The tty wrapper runs OpenCode / Claude / Codex / etc when it starts up and is given access to a repo via volume mount. From there, the "agent" either gets instructions from the websocket or it pulls tasks from Linear. Think ECS but each service instance is an agent.
I can login, create a task, look at task results, approve PR's, deny PR's, retask an agent, or take one over for my own exploratory endeavors.
