Not affiliated with them, but this lets you view Claude Code, OpenCode and I guess other harnesses like Codex in the same session https://paseo.sh/

I didn't really care about their mobile app and the worst experiences were sometimes the sub-agents within OpenCode freezing and refusing to report their status (though this also happened with Kepler by the GitKraken folks).

Roll your own harness or use an open source harness with a Codex subscription.

I maintain a Claude subscription for Fable but seldom use it.

I created Circus Chief to solve this (and other) problems. Use whatever providers you want with it.
