    From the README

    WhatsApp, native and fast. A lightweight WhatsApp app for Linux, macOS, and Windows.

    ZapFast is a WhatsApp client written in Rust with egui and fastframe, the framework behind a family of native desktop apps. It links to your phone as a companion device through whatsapp-rust and has no browser engine. In our Linux test it opens in under a second and uses about 200 MB of idle RAM, against 1.13 GB for WhatsApp Web. See the measurements.

    The interface is available in English, Chinese (Simplified and Traditional), French, German, Indonesian, Italian, Portuguese (Brazil), Russian, Spanish, and Turkish.
