Alternatives
Happy Coder alternatives in 2026
Happy Coder is a great free, MIT-licensed mobile client if you live in Claude Code, Codex, or Gemini CLI. But it doesn't cover OpenCode, the laptop must stay on, and it's a community-driven project (currently free with no paid tiers). Here are the alternatives worth knowing — starting with the one we make.
Why developers look for Happy Coder alternatives
- You use OpenCode and Happy Coder does not support it.
- You want a native mobile app with a dedicated team behind it.
- You want a polished mobile UX built around AI coding workflows, not a terminal mirror.
- You want a clearer commercial path and roadmap.
- You want a mobile cockpit that grows into multi-agent support without forking the project.
Sesori
Sesori is the mobile client for OpenCode today, with Claude Code, Codex, and others on the roadmap. Native iOS and Android, an end-to-end encrypted relay, and a bridge architecture built to support more agents over time.
- OpenCode-first. The mobile client OpenCode users have been waiting for.
- Native iOS and Android designed around AI coding workflows.
- End-to-end encrypted relay (X25519 + XChaCha20-Poly1305). Only opaque traffic reaches it.
- Dedicated team and roadmap.
- Bridge plugin model designed for multi-agent support.
