AI coding agents are powerful—but they chain you to your terminal. HAPI changes that. Working with native Claude Code / Codex from your phone while hiking. Your AI runs locally on your machine; you control it remotely. When you're back at your desk, reclaim your native terminal—no session loss, no context restart. 🔄 Seamless handoff — Switch freely from local/remote mode. 🏠 Local-first — Your data never leaves your machine. No cloud, no E2E complexity. ⚡ One command — hapi server and done.

Hey everyone! 👋 I built HAPI because I was tired of being chained to my terminal. Like many of you, I use AI coding agents (Claude Code and Codex) for hours every day. They're incredible—but they come with a hidden cost: you can't leave. Every few minutes, there's something waiting. "Approve file edit?" "Which approach should I take?" "I ran into an error—what should I do?" Miss one question, and your agent sits idle until you're back. I first discovered Happy, a cloud-hosted solution for this problem. But the server kept going down—not happy. So I tried self-hosting it. The deployment was incredibly complex: I never got it running successfully... even less happy. That's when I decided to build something different. **The key insight**: If you're self-hosting for personal use, you don't need all that complexity. No multi-user auth. No E2E encryption (your data never leaves your machine anyway). No distributed systems. Just a simple local server that connects to your phone. **The key design decision**: HAPI wraps your native AI agent instead of replacing it. When you're at your desk, you use Claude Code exactly as you always have—same terminal, same experience, same muscle memory. When you step away, HAPI lets you seamlessly take over from your phone. Press double-space and you're back in local control. No context loss, no session restart. The approach evolved as I built it: - Stripped out E2E encryption from Happy and used Bun to build everything into a single binary - Discovered the real value was seamless handoff between local and remote—added local mode for Codex - Built a proper PWA so it feels like a native app - Added a full terminal mode so you can do anything from your phone The result: I can go hiking, reply to my AI's questions, approve changes, even run terminal commands from my phone—then go back to enjoying the trail. All while my AI keeps coding on my powerful desktop machine. **Huge thanks to the Happy team** for the original inspiration and groundwork. HAPI wouldn't exist without their pioneering work on remote AI agent control. We took a different architectural direction, but the vision came from them. Would love your feedback! What features would make this more useful for your workflow?
