Run official Claude Code / Codex / Cursor Agent / Grok Build / OpenCode / Kimi / Copilot / Antigravity / Pi / DeepSeek Harness sessions and control them remotely through native iOS / Android apps, Web / PWA, or Telegram Mini App.
Why HAPI? HAPI is a local-first alternative to Happy. See Why Not Happy? for the key differences.
- Seamless Handoff - Work locally, switch to remote when needed, switch back anytime. No context loss, no session restart.
- Shared Codex Sessions - Use Codex from your terminal and phone at the same time. Requires Codex 0.154.0+. Usage and limits.
- 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, DeepSeek Harness—different agents, one unified workflow.
- Terminal Anywhere - Run commands from your phone's browser or desktop web app, directly connected to the working machine.
- Voice Control - Use dictation in native apps, or talk to your AI agent hands-free with the web 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.

Use hapi <agent> [options] to start an agent directly, for example hapi claude
or hapi codex. Scripts must specify the agent explicitly. hapi --help shows
HAPI's commands and supported agents.
The hub displays a URL and two QR codes. Then connect a client:
- Web / PWA (free): open the web URL in a browser, or scan the web QR code. Install it as a PWA for a home-screen app and push notifications.
- Native apps (paid): install HAPI from the App Store or Google Play, then scan the companion QR. See Native apps for pairing.
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
- Web / PWA (free) - The full-featured web app, including the remote terminal and voice assistant. Works in any browser and installs as a PWA. See Web / PWA.
- Native iOS / Android apps (paid) - SwiftUI/UIKit and Kotlin Compose clients with chat, approvals, session creation, files, dictation, and native push notifications. See the native app guide for capabilities and pairing.
Developers can build the apps from source: iOS, Android. Protocol: client contract.
Requires Bun 1.4.4.
