Too many limitations, for now I'll stick with self-hosted https://github.com/tiann/hapi and Tailscale
What are the drawbacks of HAPI? Seems too good to be true. Will give it a try.
Doesn't look like it has proper worktree management. UIs that abstract away worktrees are very powerful. I vibe coded my own (https://github.com/9cb14c1ec0/vibe-manager), which unfortunately doesn't have the remote component that hapi does.
