weishu 46fc83d211 feat: cut relay tunnel bandwidth with compression and SSE replay
Relay-metered traffic drops on every channel that carried avoidable
bytes; binary payloads (attachments, voice audio) are unchanged.

Hub:
- gzip /api/* JSON responses, gated by q-aware Accept-Encoding
  negotiation (explicit gzip;q=0 beats a wildcard in either order;
  hono's compress() alone matches by substring)
- enable WebSocket permessage-deflate and default flagless ws.send()
  to compressed frames - Bun negotiates the extension but compresses
  nothing unless each send opts in, and @socket.io/bun-engine never
  passes the flag (measured 96 KB terminal payload -> 608 B on wire)
- replay missed SSE events on reconnect: 256-event/2MB ring buffer,
  per-process epoch ids bound to the authenticated namespace so a
  token swap can never resume from a foreign cursor, standard
  Last-Event-ID header preferred over the ?lastEventId fallback,
  live broadcasts queued until the replay flushes to preserve order

Web:
- skip the full sessions/details/messages resync when the hub answers
  resume:ok - a phone unlock now costs a handshake plus the gap delta
  instead of refetching everything
- own every EventSource retry path: take over browser-native
  CONNECTING retries, defer reconnects while the tab is hidden, and
  raise the backoff ceiling to 5 min after repeated failures
- drop the 30s skills/slash-commands polling; refresh on demand
  without blocking the suggestion menu behind a stalled CLI RPC
- remember the websocket upgrade across terminal socket reconnects

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.

For self-hosted options (Cloudflare Tunnel, Tailscale), see Installation

Docs

Build from source

bun install
bun run build:single-exe
