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
Self-hosted servers using a private certificate authority — mkcert and similar — now work over https. Install your CA on the device and Prism will trust it. Previously only certificates from public authorities were accepted, so LAN-only setups had no option but plain http.
How to install
Download the APK from the button at the top of this page.
Allow “Install unknown apps” for your browser or file manager only, not for every app.
Open the downloaded file and confirm the installation.
If installation fails with “App not installed,” remove an earlier build of the same app first. A signature conflict is the usual cause.
Data safety
Every file is checked against its published SHA-256 before it is listed.
Files are scanned for malware on every update.
The permissions each app requests are listed on its own page.
Read the full safety policy for how we test, flag, and delist files.
