Download the offline build

Prefer a native app? The desktop builds run fully offline. The in-browser version needs no install at all.

macOS

Version 3.2.1 · Universal macOS application · approximately 53 MB. Runs natively on Apple Silicon and Intel Macs and requires macOS 13 or newer.

This release corrects the v3.2.0 self-contained Qt runtime packaging defect. The application is ad-hoc signed and is not notarized, so macOS may require you to Control-click the app, choose Open, and confirm on first launch.

macOS — Apple Silicon & Intel

Windows

Version 3.2.0 · Windows x64 · approximately 24 MB. This one-file portable launcher includes the application and its Qt runtime. The first run prepares a local cache; later launches start from that cache.

Download and double-click the file—no installation or administrator access is required. This build is not code-signed, so Microsoft Defender SmartScreen may require More info → Run anyway.
