UnifiedPush: A decentralized, open-source push notification protocol (2022) (f-droid.org)
A modern Android smartphone relies on a lot of services, from app stores and calendars to messaging and push notifications. Most of them have open alternatives, but until now, the only option for push notifications was Google’s proprietary service, Firebase Cloud Messaging (FCM). UnifiedPush is a new alternative that allows you to get push notifications without being tied to a single company.
