An installed WebAPK reads manifest theme_color once at install time and uses it as a fixed toolbar color; runtime document theme-color updates never repaint it, only the icon tint follows. With theme_color set to white the status bar stayed white while dark app themes turned the icons white too, hiding the clock, signal and battery. Chrome falls back to white when no theme color is present and to black when the system is dark and no dark color is declared, so dropping theme_color gives a status bar that follows the Android system theme with icons that stay readable in both. The dark manifest override that could have supplied a per-scheme color is not an option: Chrome removed dark color parsing from the manifest parser in 128 and the mojom fields are marked obsolete. The document theme-color meta keeps driving every non-installed surface, so browser tabs are unchanged.
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.
- 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 # 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
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
