If all you need is to get a notification on your phone, you can use web browser Notification API for free. All you need is a https web server with properly configured certificates and DNS entry, which you can also get for free.
This is quite expensive compared to SimplePush.
cool stuff couldn’t find how to self-host it though, got links?
you mean simplepush.io is a provider of an ntfy server?
Yup
wild, their repo does not reflect that at all https://github.com/simplepush
So they reinvented MQTT?
Thanks, i did not know about MQTT! (https://mqtt.org/ for others like me) Looks great, at first glimpse harder to use, but i will give it a honest shot.
ntfy appears to have the advantage of being easily usable with generic webhooks, whole MQTT is a bit more mature and featureful.
The thing is on stupid phones you have to install a separate app, that lowers too much the adoption
are there any notifications that don’t come from separate apps? System notifs perhaps, but one could argue they come from the “system apps”. I figure this system is specifically designed for personalised notifications from things one administer independently. Such as backups, home-server monitoring, sovereign home appliances etc… I’m not codelitrary enough to figure out whether this can be built in to a 3rd party app, but i imagine it to be possible but would require a server somewhere eitherway. Kind of like NextcloudServices offers (Simply fetch Nextcloud notifications on devices without Google Play services) https://f-droid.org/packages/com.polar.nextcloudservices/
Otherwise the closest thing would be leveraging the browser notification API. Still an app, but at least one that most users have installed (see https://fed.dyne.org/comment/53589)
