Meron

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.

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.

Architecture

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.

Development

See CONTRIBUTING.md for prerequisites and instructions on building, testing, and translating Meron.
