Use the official web client at app.vulpio.app. You can install it to the home screen. This device’s keys stay in a password-protected browser vault.
Open app.vulpio.appWhat you need
- Windows: Windows 10 or 11, 64-bit, with WebView2 (already present on current Windows 11).
- Android: Android 8 or newer on ARM64. The public APK is not a Play Store build yet.
- Web: A current Chromium, Firefox, or WebKit browser with WebCrypto.
- Account: an email address for signup and recovery. Email restores the account, not old encrypted history by itself.
Not published yet
macOS, Linux, and iOS clients are part of the same official family and are not in this early-access set. If someone offers a Vulpio build from anywhere except vulpio.app or app.vulpio.app, do not install it.
After you install
Create an account, save your recovery key when the app offers it, and join a Den from an invite. If you were sent here from a link like vulpio.app/join/XXXX-XXXX, come back to that page once the app is installed.
This is an early-access build. It proves the product flow. It is not a substitute for an independent cryptographic audit. Do not move a production community onto it until that review is done.
