A lightweight WhatsApp app for Linux, macOS, and Windows. Chat, send voice messages, and share files.
Opens in under a second and uses 150MB of RAM. No browser engine.
Play, seek, and record voice messages in the chat. OGG/Opus support is built in.
Photos, GIFs, stickers, documents, polls, locations, and link previews appear in the chat. Add captions before sending files.
Closing the window keeps ZapFast linked in the tray. Notifications show the chat picture, and muted chats stay quiet.
Search, switch chats, reply, and record with shortcuts. Select and copy text, including across messages.
