Render ExitPlanMode and exit_plan_mode Markdown from input.plan in iOS and Android conversations. Preserve approvals, raw source and diagnostics while hiding empty output placeholders and prewarming plan documents. Add generated protocol fixtures and native regression coverage for long plans, live updates, recycling, themes and typography.
HAPI
Run official Claude Code / Codex / Cursor Agent / Grok Build / OpenCode / Kimi / Copilot / Antigravity / Pi / DeepSeek Harness sessions 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.
- Shared Codex Sessions - Terminal and Web/phone use the same Codex engine simultaneously; normal terminal/Runner lifecycle, with resume after exit. Requires Codex 0.154.0+. Lifecycle 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 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 # choose an agent and start a session
hapi server remains supported as an alias.
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 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
Native apps (iOS / Android)
Fully native SwiftUI and Kotlin Compose clients are in development under ios/ and android/. They pair with your hub by scanning the same terminal QR code as the web app, and follow the same protocol — see the client contract docs.
Build from source
Requires Bun 1.4.0.
bun install
bun run build:single-exe
