Privacy-first UnifiedPush distributor with an optional self-hosted server

F-Droid repository metadata

Prism is a UnifiedPush distributor that uses Mozilla's push server for transport. It optionally pairs with a self-hosted Prism server, which can monitor your Proton Mail inbox and route notifications to Signal, Telegram or this app.

The Prism server also accepts notifications from any source via a webhook API compatible with ntfy.

What’s new

Prism now speaks 19 languages: German, French, Spanish, Russian, Ukrainian, Polish, Czech, Dutch, Italian, Portuguese (Brazil), Turkish, Chinese, Arabic, Hebrew, Indonesian, Hungarian, Estonian, Galician and Esperanto.

Releases are also built and published to Google Play automatically now.

How to install

  1. Download the APK from the button at the top of this page.
  2. Allow “Install unknown apps” for your browser or file manager only, not for every app.
  3. Open the downloaded file and confirm the installation.
  4. If installation fails with “App not installed,” remove an earlier build of the same app first. A signature conflict is the usual cause.
