Run official Claude Code / Codex / Gemini / OpenCode 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.

• 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, Gemini, OpenCode—different models, 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.

The terminal will display a URL and QR code. Scan the QR code with your phone or open the URL to access.

HAPI means "哈皮" a Chinese transliteration of Happy. Great credit to the original project.
