UnifiedPush is specifications and tools that let the user choose how push notifications are delivered. All in a free and open source way.
The application that gives notifications is called a Distributor. If you don’t care about using Google’s FCM, look at the download links of fcm-distributor.
Currently, the simplest way is to host your own Gotify server and install the associated distributor.
You should use the UnifedPush connector library for your framework. If it doesn’t already exist for your framework/language, contributions are welcome.
The distributors page has a recap of all the options.
See the application list. If an app isn’t in there, feel free to ask in the UnifiedPush Matrix (bridged on Freenode IRC) or ask the application’s dev team.
IOS doesn’t support running services in the background, so running a UnifiedPush distributor won’t be possible without jailbreaking or Apple’s approval for the foreseeable future. If someone has a solution, share that in the chat.
Yes! UnifiedPush doesn’t define a transport between the provider and the distributor. Just implement the UnifiedPush distributor API, and your service will be compatible with any existing app that uses UnifiedPush!
