- pi-web (https://pi-web.dev/): a web frontend for the Pi coding harness which can multiplex pi sessions across multiple machines
- herdr (https://herdr.dev/): a fairly polished agentic multiplexer TUI, can easily spawn or destroy windows based on subagent activity
- firstmate (https://github.com/kunchenguid/firstmate): a meta environment for coding harnesses - more naturally handles spawning and communicating with subagents, managing worktrees, and other SDLC functions, and has a fairly large number of constraints thru bash scripts to ensure better results with less intelligent models
