OneSignal

Push notifications (web + mobile)

Free tier + paidEmail, forms & notificationsonesignal.com

What it is

Push notification platform covering iOS, Android, web push, in-app messages, email and SMS from one dashboard. Handles APNs and FCM credentials, audience segmentation, A/B tests, scheduled sends and journeys. SDKs for React Native, Flutter, Expo, Unity, native platforms and plain JavaScript.

Why it earns a slot

Mobile push is genuinely unlimited on the free plan, which nobody else offers. It also spares you the misery of managing APNs certificates and FCM server keys by hand.

Know before you commit

Growth billing switches to per monthly-active-user, so cost scales with app installs rather than messages sent. The free plan limits journeys and segments, and web push counts subscribers, not sends.
