Show HN: Pocketty – iPhone SSH terminal that pings you when an agent is blocked

Hello~! pocketty is an SSH terminal for iPhone and iPad, made for herdr. herdr keeps your agent panes alive on your computer and knows the state of each one: working, needs you, or done. I made this in anger/desperation for the latter half of my recent paternity leave. Nap traps are sweet, but there's only so much doom-scrolling and movie-watching I can handle... In any event, I've been using it for the last couple months and no longer have to be my desk anymore to be productive. Now the nap-traps are still productive (when i want them to be) ! How it works: - The app talks to your computer directly over plain SSH. Tailscale is the easy way to reach it from anywhere but any SSH host you can reach works. - A small Rust daemon on the host watches herdr. When a pane needs you, it seals the alert to your phone's key with HPKE (X25519, ChaCha20-Poly1305). A stateless relay (pocketty's) on Cloudflare Workers passes the sealed bytes to APNs (Apple Push Notification servers), and a notification extension opens them on the phone. The relay can't read them and keeps nothing. - Your SSH key is made in the Secure Enclave and can't be exported. - The terminal uses libghostty-vt for state and draws with wgpu on Metal, so full-screen TUIs look like they do on your desk, albeit narrower. - Diffs for each agent turn, a file browser, and previews of `localhost` dev servers your agent starts, all through the same SSH connection. No port forwarding to set up. herdr and the daemon are optional. Without them, it's a normal SSH client. There's no account to set up and no analytics or tracking in the app. The app runs a 14-day free trial, with full feature access. Then, if you're as happy as I am with it, then it can be yours forever with a one-time purchase: $99 for the first two weeks (launch promo) then $129 after that. Happy to answer anything about the sealed push setup or running libghostty on iOS.
