Messages that spark joy
Meron is a fast and secure email app with chat and kanban views.
Install from Microsoft Store, Flathub, Snap Store, Google Play, App Store, or download installers from GitHub.
AppImage notes
The Linux AppImage and tarball use the system WebKit, so they need
webkit2gtk-4.1 installed (libwebkit2gtk-4.1-0 on Debian/Ubuntu,
webkit2gtk4.1 on Fedora, webkit2gtk-4.1 on Arch). The Flatpak and snap
bundle their own and need nothing extra.
The AppImage carries update information and ships an accompanying
meron-linux-amd64.AppImage.zsync, so AppImageUpdate, AppImageLauncher, AM and
similar tools can update it by downloading only the changed blocks. The in-app
updater works as well and always fetches the full image.

| 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.
