Pick a platform

Each platform ships when its build is signed and the autopurge invariant has survived the install path. Status is the truth, not a teaser.

Web LIVE
PWA · INSTALLABLE

Works in Chrome, Safari, Firefox, Edge. Install via your browser's "Add to Home Screen" for a windowed app experience.

macOS BRING-UP
.dmg · Apple Silicon + Intel

.dmg builds require macOS hardware (Apple's signing toolchain doesn't cross-compile from Linux). Notarization gates the public drop. Join the notify line.

Windows LIVE

Android & Chromebook LIVE · BETA
Capacitor · sideload

Direct .apk · Play Store listing in progress. Android 7+ (API 24). Chromebooks: opens via the Android subsystem.

Integrity of the build itself

If the binary on your machine doesn't match the one we shipped, the cryptography doesn't matter. The plan for verifying every download:
