This sounds like a mashup of of several things I've been playing with lately...

- 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

have you tried Orca at all? I'm wondering between switching to herdr from it

I've been working on collie[1] a plugin for herdr that runs a web app on the herdr host which can then be served via tailscale for example. This has made accessing my agents on the go a lot easier, paired with session persistence from herdr it's been quite nice to work with.

Since you seem curious about these types of tools, might I interest you in ouijit https://ouijit.com/ https://github.com/ouijit/ouijit

Its intended as a terminal agent orchestrator aimed at power users who want a little more design than what I like to call 'hackerman' UXes.

While not terminal-only, I've been using Orca (https://github.com/stablyai/orca) for the past week and it's been a great experience
