| Component | Stack | Location |
|---|---|---|
| Core engine | Rust | meron-core/ |
| Desktop app | Go + Wails | root (*.go) |
| Desktop UI | React + TypeScript + Tailwind | frontend/ |
| Mobile apps | Kotlin Multiplatform (Android/iOS) | mobile/ |
The Rust core runs as a sidecar process on desktop (driven over JSON-lines stdio) and is linked directly into the mobile apps over FFI/JNI. This keeps all mail, feed, and storage logic in one place across every platform.
