Another option that does all this and more for open code: https://github.com/btriapitsyn/openchamber

Not affiliated with that project, but have been using it for a few weeks and it blows every other 'GUI for the CLI agents' I've tried out of the water in terms of both features and just working snappily/consistently.

Also totally free, and actively being improved by the solo maintainer and an active community of contributors.

Omnara providing a tunnel for you is nice, but considering Tailscale is dead simple and free, feels hard to justify $20 a month for what looks like considerably less features than openchamber

Yeah, this looks great for OpenCode (which we're planning on adding soon!), but I personally have Claude Code and Codex subscriptions, which Omnara supports. We also support syncing your local session to a cloud sandbox to continue your session, and in the cloud sandbox, we provide LLM tokens. As well as our voice agent costs are covered by us.
