# HAPI

HAPI means "哈皮" a Chinese transliteration of [Happy](https://github.com/slopus/happy). Great credit to the original project.

Run Claude Code / Codex / Gemini 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?](docs/guide/why-hapi.md) for the key differences.
