Sesori vs Happy Coder
TL;DR
Choose Happy Coder for an MIT-licensed option that supports its listed agent set. Choose Sesori if you use Cursor or need its seven named assistant integrations in one mobile app.
Happy Coder is an MIT-licensed mobile client for Claude Code, Codex, and OpenClaw. Its README describes end-to-end encryption for CLI-wrapper sessions. Sesori supports OpenCode, Codex, Cursor, Claude Code, Pi, OMP, and Hermes through native iOS and Android apps and a Bridge designed for more assistants.

Side by side
| Feature | Sesori | Happy Coder |
|---|---|---|
| Primary agents | OpenCode, Codex, Cursor, Claude Code, Pi, OMP, and Hermes. | Claude Code, Codex, and OpenClaw, plus any ACP-compatible agent. |
| License | Source-available Bridge under the Functional Source License (FSL). | MIT-licensed across the stack. |
| Mobile app | Native iOS and Android. | iOS, Android, and a web client. |
| How it attaches to the agent | Bridge CLI runs beside your local assistant and pairs to your account. | CLI wrapper: run `happy` instead of `claude` to mirror the session. |
| Relay model | Ordinary phone-to-Bridge session payloads are end-to-end encrypted (X25519 + XChaCha20-Poly1305). The relay still handles connection and routing metadata. | Its README describes end-to-end encryption. Repository documentation describes legacy NaCl secretbox and AES-256-GCM data-key variants; review current deployment details in its source. |
| Voice input | Native voice for coding-session prompts and replies. | Built-in voice agent using Eleven Labs for speech-to-text. |
| Pricing | Free to use. Bridge is source-available under the Functional Source License (FSL). | MIT-licensed core; verify current charges for optional hosted or voice features in the app. |
| Roadmap focus | More assistant integrations, polished native UX, and account-based onboarding. | Community-driven with strong Claude Code coverage and an active GitHub repository. |
