ZapFast: a fast, native WhatsApp client in Rust and egui

A browser-free WhatsApp client that starts in under a second — ZapFast is a native WhatsApp desktop client built in Rust with egui, skipping any embedded browser engine. It links as a companion device via whatsapp-rust and, per the project's own benchmarks, opens in under a second using about 200 MB idle RAM versus 1.13 GB for WhatsApp Web. It supports Linux, macOS, and Windows, with the UI localized into 11 languages.
