Score: 7.3/10 (Innovation: 6, Technical: 8, Documentation: 8, Utility: 7)

ZapFast is a native, cross-platform WhatsApp desktop client written in Rust with egui and a custom fastframe UI framework. It avoids the browser engine entirely, linking to your phone as a companion device via whatsapp-rust, and claims dramatically lower resource usage than WhatsApp Web while supporting voice/video calls, media, multiple accounts, and an encrypted local message archive.

Target audience: Linux desktop users and developers seeking a lightweight, privacy-conscious WhatsApp client
