A suspended mobile tab can lose its SSE connection without the browser ever noticing (no FIN/RST arrives). On resume the client used to wait for the 90s heartbeat watchdog or lean on the native EventSource retry, which can hang on a dead pooled socket - leaving a persistent "Reconnecting... (stream error)" banner while the UI keeps working. - useSSE: on visibility resume, distrust the connection after one missed heartbeat interval (45s) instead of 90s - useSSE: abandon connection attempts that don't open within 10s (hung on a dead pooled socket after resume) instead of waiting for the watchdog; force bypasses the one-shot reconnect guard for the new attempt cycle - useSSE: first reconnect attempt is immediate; exponential backoff starts from the second attempt - ReconnectingBanner: localize connect-timeout and transport-error reasons (transport-error is already emitted by current code but fell through unlabeled) Fixes #1559. Reimplements the reconnect half of #989 (closed unmerged) on top of the current scheduler (hidden-tab deferral, slow backoff, replay cursor).
HAPI
Run official Claude Code / Codex / Cursor Agent / Grok Build / OpenCode / Kimi / Copilot / Antigravity / Pi sessions locally and control them remotely through a Web / PWA / Telegram Mini App.
Why HAPI? HAPI is a local-first alternative to Happy. See Why Not Happy? for the key differences.
Features
- Seamless Handoff - Work locally, switch to remote when needed, switch back anytime. No context loss, no session restart.
- Native First - HAPI wraps your AI agent instead of replacing it. Same terminal, same experience, same muscle memory.
- AFK Without Stopping - Step away from your desk? Approve AI requests from your phone with one tap.
- Your AI, Your Choice - Claude Code, Codex, Cursor Agent, Grok Build, OpenCode, Kimi, Copilot, Antigravity, Pi—different agents, one unified workflow.
- Terminal Anywhere - Run commands from your phone or browser, directly connected to the working machine.
- Voice Control - Talk to your AI agent hands-free using the built-in voice assistant.
- Workspace Browser - Opt-in via one or more
hapi runner start --workspace-root <path>flags: browse scoped file trees from the web and start sessions in allowed subdirectories.

Getting Started
npx @twsxtd/hapi hub --relay # start hub with E2E encrypted relay
npx @twsxtd/hapi # run claude code
hapi server remains supported as an alias.
The terminal will display a URL and QR code. Scan the QR code with your phone or open the URL to access.
The relay uses WireGuard + TLS for end-to-end encryption. Your data is encrypted from your device to your machine.
