About Prism
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 in 1.4.2
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 Prism
- Tap Download — the app's official page on F-Droid opens.
- Install it with the F-Droid app (recommended, for automatic updates), or use the download button on that page.
- If Android asks, allow the F-Droid app or your browser to install apps, then tap Install.
- Open Prism from your app drawer.
