README

From crmne/zapfast · license MIT · fetched Oct 30, 2026

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.

Features · Install · Link your phone · Help

Your chats, on your desktop

FeatureWhat you can do
MessagesSend formatted text, replies, edits, reactions, forwards, pictures, files, stickers, GIFs, polls, and voice messages.
Media in the chatPlay voice messages, videos, round video messages, GIFs, and animated stickers in place.
Your historyKeep your chats in an encrypted archive on this computer, and fetch older messages from your phone as you scroll.
Several numbersLink more than one WhatsApp number and switch between them in one window.
Desktop controlsUse keyboard shortcuts, select and copy text across messages, and stay linked in the tray with notifications.
ThemesChoose light, dark, system appearance, or custom colours. On Omarchy, follow your desktop theme.
PrivacyHide locked chats behind a code, or the whole window behind an app lock. Nothing goes to a server of ours.

Install

PlatformInstallation
macOSbrew install --cask crmne/tap/zapfast, or download the Mac app.
Arch Linuxyay -S zapfast-bin
WindowsChoose your build on the Download page.
Other LinuxFind Nix, AppImage, and other options on the Download page.
From sourceFollow Getting started for dependencies and commands.

Link your phone

  1. Open ZapFast. It shows a QR code.
  2. On your phone, open WhatsApp, then Settings, Linked devices, Link a device, and scan the code. Or click Link with phone number and enter the eight-character code on your phone.
  3. Your recent chats arrive from the phone. Older messages follow as you scroll up.

The link survives restarts, and your phone does not need to stay online to read what ZapFast has already stored. See Getting started for the full walkthrough and How it links for the details.

Contributing

Read CONTRIBUTING.md before opening an issue or pull request. To look at the interface without a WhatsApp account, run:

cargo run --features demo -- --demo

AGENTS.md describes the architecture, DEMO.md the demo pages, screenshots, and recorded tours, and PACKAGING.md releases and packages.

Native notifications use Fastframe on Linux, macOS and Windows. ZapFast keeps its account/chat routing, privacy settings, notification limits and sound previews. Clicks open the announced message; reading a chat withdraws its tracked notifications. OS permissions and notification presentation still apply.

More native apps

Want Spotify just as fast and native? Spotifast is ZapFast's sibling. Both are built on fastframe.

Acknowledgements

ZapFast uses whatsapp-rust, egui, fastframe, the Inter typeface and Noto Color Emoji (OFL), and Lucide icons (ISC), also used for the chat wallpaper doodles. The notification sounds are Pidgin's, under the GPL-2.0 (see assets/sounds/).
