Firebase FCM vs OneSignal Push
Two push notification providers, compared on price, features and ratings — so you can pick fast.
Updated June 2026
The verdict
FCM is Google's free push transport — unlimited and reliable, but bare-bones: no segmentation UI, journeys, or delivery webhooks. OneSignal builds a full engagement layer on top — advanced segmentation, in-app, journeys, A/B testing, geofencing, and dashboards — with a generous free tier and paid plans from ~$9/mo. Pick FCM if you want free, code-level control; OneSignal if you want marketing features without building them.
