history

Project history and usage

ZapFast is an independent native Rust desktop client that links to WhatsApp as a companion device, supports common messaging and media operations, and keeps synchronized chat history in a local encrypted archive.

Project history

The application was originally named FastsApp and developed as an unofficial native WhatsApp companion client. It links as a companion device rather than embedding WhatsApp Web, and stores synchronized history locally.

Version 0.13.0 introduced the ZapFast package and executable names. The application retained migration paths from FastsApp and the still earlier fastwhatsapp data directories while expanding multi-account, privacy, messaging and desktop-integration features.

Adoption history

ZapFast distributes native builds for Linux, macOS and Windows, with documented Homebrew, Arch, Nix, AppImage and standalone installation routes. Its multi-platform packaging and in-application updater make it usable beyond source-build audiences.

The project is recent, so available evidence supports active packaging and development rather than broad or long-established adoption.

How it is used

Open ZapFast and scan its QR code from WhatsApp's Linked devices screen, or use phone-number linking. Each linked number receives separate session, archive, settings and cache storage.

Users can send messages and media, record voice messages, manage multiple linked numbers and keep the application connected in the system tray. Because ZapFast is unofficial, its documentation warns that using it may carry account risk.

Why package nerds care

ZapFast is an unusual desktop package because it replaces the common embedded-web-view approach with a Rust and egui client linked through whatsapp-rust. It keeps chats in a local encrypted archive while exposing the file layout clearly enough for backup and troubleshooting.

Its rename and migration support are also noteworthy: packages, executable names and per-user state moved from FastsApp to ZapFast while preserving existing linked sessions and local archives.
