Great question!

I also haven't seen comparable remote control functionality in open source tools- even in the closed source world, Codex and Cursor are in my experience the only very stable remote control experiences right now.

As for Proliferate, we don't currently support mobile access as a first class feature- we have a beta version available but don't want to release to GA yet as we're trying to match the above Codex / Claude quality and stability bar first.
