From GitHub's daily star counts.

Checked 14 Oct 2026 on GitHub.

Overview

Happy is an Expo mobile and web client, an npm CLI (`happy claude`, `happy codex`) that wraps the Claude Code and Codex harnesses, and a relay server for end-to-end encrypted sync. Sessions started in the terminal can be continued from a phone. The newer multi-model Happy Harness (Claude, Codex, Grok) lives in the separate desktop app and happy-agent repositories.

Who it is for: Developers who want to drive Claude Code or Codex sessions from their phone

Strengths

Continue terminal Claude Code and Codex sessions from iOS, Android or web
Mobile sync between devices is end-to-end encrypted via a relay server
MIT licensed; the relay server is in the repo for self-hosting
Reuses existing Claude, Codex and Grok subscriptions rather than adding billing

Weaknesses

Multi-model Harness and multiplayer sessions are in other repos, not this one
Original CLI only wraps Claude Code and Codex, not Grok
README gives no self-hosting steps, ports or resource requirements
Needs an existing Claude or Codex subscription or install to be useful

What it needs

no GPU
Docker
Needs Claude Code, Codex, Node.js and npm
Models: Claude, Codex, Grok

How to choose

Check which models it can use: your own keys, local models, or only the vendor's.
See what it may do without asking (edit files, run shell, push) and how you approve.
Prefer agents that work in a branch or worktree you can throw away.
