ZapFast: a fast, native WhatsApp client in Rust and egui
ZapFast is a lightweight, native WhatsApp desktop client for Linux, macOS, and Windows, written in Rust with egui. It links to your phone as a companion device without a browser engine, supports full messaging features, encrypted local chat history, multiple linked numbers, themes, and privacy locks. The README claims it opens in under a second and uses about 200 MB idle RAM vs 1.13 GB for WhatsApp Web.
Why now: It was featured on Hacker News, likely drawing attention to its Rust/egui approach and published benchmarks showing large memory savings over WhatsApp Web.
Who it is for: WhatsApp users on desktop—especially Linux users—who want a fast, lightweight native alternative to WhatsApp Web or Electron wrappers.
