Mainplane

Mainplane is an open-source agent ecosystem that coordinates AI agents across computers.

Mainplane is an open-source agent ecosystem that runs as a single Go binary under an MIT license. It turns computers into an always-on local AI shed so agents keep working when laptops close. Users bring their own API keys or subscriptions for models. The platform includes a first-class TUI, a sessions API, shared file drives for concurrent agent access, and a private mesh network. It supports browser and computer use while keeping API keys isolated on the server.
