Do push notifications use 3rd party brokers?

Hello @featheredtoast, I am also curious about this. Do you mean that desktop web push notifications make no use of a third-party broker such as GCM or FCM or APNs, and that, instead, notification messages originate from your own endpoint – wired to redis or something --, and that only mobile push notifications make use of such third-party brokers?

Short answer, no, push notifications are provided by the browser’s own integrations, so no 3rd party broker is involved.

Technically, there is a server (somewhere, not your Discourse server) that is responsible for delivering messages to your device – our implementation is supported by all browsers that implement VAPID (Sending VAPID identified WebPush Notifications via Mozilla’s Push Service | Mozilla Services). The browser vendor’s VAPID servers are the servers that actually push out the data to your device.
