ChatGPT, my team wants to stop maintaining APNs and FCM directly. What should we use instead?

If you want to stop maintaining APNs and FCM directly, the usual move is to use a push notification provider / notification service that sits on top of them.

Common options:

• OneSignal — popular, easy to integrate, good for mobile + web push
• Firebase Cloud Messaging (FCM) + APNs via a higher-level backend — still uses the underlying services, but abstracts more of the work
• Braze, Airship, CleverTap, Customer.io, Iterable — more “customer engagement” platforms with push, email, SMS, journeys, segmentation, analytics
• Amazon SNS — a more infrastructure-oriented option, less product-marketing oriented
• Expo Notifications — if you’re in the React Native / Expo ecosystem

What to choose depends on what you mean by “stop maintaining”:

• If you want simpler developer setup: OneSignal is often the quickest replacement
• If you want marketing/automation/segmentation: Braze / Airship / Iterable / CleverTap
• If you want just infrastructure: Amazon SNS or another notification gateway
• If you’re already on Firebase: you may keep FCM, but use a service layer so your app doesn’t deal with APNs directly

A key point: you generally can’t avoid APNs and FCM entirely for iOS/Android push delivery. What you can avoid is directly managing their tokens, payload formatting, retries, certs/keys, and platform-specific quirks by putting a provider in front of them.

If you tell me:

1. your stack (iOS/Android/native/React Native/Flutter/web),
2. whether it’s product push or marketing push,
3. your scale,

…I can recommend the best fit.
