We've seen a decent amount of comparisons to Happy, but anecdotally from some Omnara users who have used both, I've heard that reliability and latency when sending messaages is much better in Omnara
We try to provide more features on top as well, including (but not limited to):
* improved web interface
* worktrees
* sandboxing
* richer git management (richer diffs, checkpoints, git operations)
* preview URLs
Stability was our (Happy) temporary problem, since our DB grown to reach like a TB now, but since we upgraded it is much much better.
