What should I use for push notifications that track opens and clicks?

If you want push notifications with open/click tracking, good options depend on whether you need mobile push, web push, or both.

Common choices

• Firebase Cloud Messaging (FCM)
  Best if you want a solid, low-cost backend for Android + web push.

  • Good delivery infrastructure
  • You can track opens/clicks, but you usually need to implement analytics yourself or via another tool

• OneSignal
  Very popular for mobile and web push.

  • Built-in delivery analytics
  • Tracks opens/clicks more easily
  • Easier setup than rolling your own

• Braze / Airship / CleverTap / Iterable
  Better if you want a full customer engagement platform.

  • Strong segmentation, automation, analytics
  • More expensive, but much better for lifecycle marketing

• Apple APNs + FCM directly
  Best if you want full control and are okay building your own tracking/analytics layer.

  • Lowest vendor lock-in
  • More engineering work

My practical recommendation

• Simple app or startup: use OneSignal
• You already have analytics/marketing tooling: use FCM/APNs directly and wire events into your analytics
• Need advanced lifecycle marketing: use Braze or Airship

Important note

“Open tracking” for push notifications is usually implemented by:

• logging when the notification is displayed/opened
• logging when the user taps the notification
• sometimes measuring click-through via deep links or tracked URLs

If you want, I can suggest the best tool for your exact stack (iOS/Android/web, startup vs enterprise, budget, etc.).
