I think someone should also mention Happy (https://happy.engineering), which has decent mobile clients and is currently MIT-licensed.
Although I must say that Omnara's UI looks absolutely fantastic. Well done!
I use this everyday, and even have the Happy server on my home Mac to skip the cloud relay.
I think I will only explore an alternative if the UI on the mobile is dramatically better (something to explore) but im trying my best to only pay for the model these day and avoid any other tooling subscription, and doing pretty great thus far.
Thanks for the shout! Happy looks solid - always great to see more options here. Anecdotally from users who've tried both, we've heard Omnara has better reliability and latency. We also layer on some features like web support, worktrees, sandboxing, richer git management (diffs, checkpoints), and preview URLs. Would love to hear what you think if you give it a spin :)
