Score Breakdown
⚙ Agent Friendliness
🔒 Security
Access token per project. Push notification data should not contain sensitive PII. SOC2 in progress. Token-based delivery through Apple/Google infrastructure.
⚡ Reliability
Best When
You have a React Native app built with Expo and want the simplest possible cross-platform push notification integration.
Avoid When
Your app is not built with Expo, or you need advanced features like topic subscriptions and segmentation.
Use Cases
- • Sending push notifications to React Native/Expo apps on iOS and Android
- • Simplifying cross-platform push without managing APNs/FCM directly
- • Batching notifications in server-side agents for efficient delivery
- • Sending notifications with receipt verification for delivery confirmation
- • Rapid mobile push integration for Expo-based prototypes and products
Not For
- • Non-Expo React Native apps (use FCM/APNs directly)
- • Native iOS/Android apps not built with Expo
- • Web push notifications
- • Large-scale consumer apps needing advanced segmentation
Interface
Authentication
Access token for authenticated requests. Basic unauthenticated access allowed but rate-limited. Token obtained from Expo account.
Pricing
Generous free tier for development. Production apps at scale should use EAS (Expo Application Services) with paid plan.
Agent Metadata
Known Gotchas
- ⚠ Two-phase delivery: first get ticket, then fetch receipt after delay to confirm actual delivery
- ⚠ Push tokens only work for apps built with Expo - pure React Native or native apps won't work
- ⚠ Notifications are not guaranteed to arrive if device is offline for extended periods
- ⚠ Batch up to 100 notifications per API call for efficiency - agents should batch sends
- ⚠ DeviceNotRegistered errors require removing stale tokens from your database to avoid waste
