One Softphone, Every Device
Native apps for desktop, mobile, and a self-hosted push gateway for always-on connectivity. Same Rust core everywhere.
Desktop
Tauri + React app for macOS, Windows, and Linux. 10MB installer, instant startup, native performance.
iOS
SwiftUI with CallKit and PushKit. Native call UI, lock screen integration, VoIP push notifications.
Android
Jetpack Compose with ConnectionService and FCM. Material You theming, native call management.
Push Gateway
Self-hosted SIP B2BUA. Maintains registrations for mobile, delivers APNs/FCM push, handles call handoff.
One Rust core, every platform
The SIP protocol library and RTP media engine are shared across desktop, iOS, Android, and the push gateway. UniFFI generates native Swift and Kotlin bindings from the same Rust code — no protocol reimplementations, no drift.
Built with Modern Technology
No legacy code. No technical debt. A clean-slate implementation using the best tools available in 2026.
Rust Core
Memory-safe, blazingly fast SIP stack and RTP media engine shared across every platform. No crashes, no memory leaks.
Tauri + React
Desktop app with native performance and a smooth React UI. 10MB installer, instant startup, no Electron bloat.
Native Mobile
SwiftUI on iOS, Jetpack Compose on Android. UniFFI generates native bindings from the shared Rust engine.
Why a complete rewrite?
Most softphones are built on aging C/C++ codebases with decades of technical debt. Aria starts fresh with Rust's safety guarantees and React's developer ergonomics, delivering a more reliable, maintainable, and performant experience.
