Best Alternatives to EAS Observe in 2025

Sentry is the go-to for full-stack error and performance monitoring. It goes beyond startup and screen metrics to capture JavaScript exceptions, native crashes, and slow transactions. Its React Native SDK works with Expo, and you can set custom traces for any screen or function. Sentry also offers release health, session replay, and a powerful alerting system, making it ideal if you need both performance and error tracking in one place.

If you're already in the Google ecosystem, Firebase Performance Monitoring provides automatic tracing for app startup, screen rendering, and network requests. It's free to start, integrates with Firebase Crashlytics for crash correlation, and offers a simple dashboard. While less Expo-specific, it works with React Native via the Firebase SDK and gives you a broad view of app performance across Android and iOS.

Datadog Real User Monitoring (RUM) is a heavyweight for teams needing deep, real-time analytics. It captures every user interaction, network call, and resource load, not just startup and screen times. You can correlate performance with backend traces and logs in Datadog's unified platform. It supports React Native and Expo, and its advanced filtering, custom dashboards, and anomaly detection are perfect for large-scale production apps.

New Relic offers comprehensive mobile monitoring with automatic instrumentation for React Native and Expo. It tracks app launch, UI hangs, and network errors, plus provides distributed tracing to see how mobile requests perform across your entire stack. Its NRQL query language lets you build custom charts and alerts. If you need enterprise-grade scalability and integration with other New Relic observability tools, this is a strong choice.

Instabug focuses on mobile app quality with performance monitoring, crash reporting, and in-app user feedback. It gives you real-user metrics like app startup and screen load, but also adds unique features like bug reporting with screen recordings and network logs. Its React Native SDK is easy to set up with Expo, and the dashboard highlights performance issues alongside user-reported problems, making it great for agile teams.

Aptabase is a privacy-friendly, open-source analytics alternative that includes basic performance tracking for React Native and Expo. It measures app open times and screen views without heavy SDK overhead, and you can self-host to keep data on your servers. While not as feature-rich as EAS Observe, it's a lightweight option if you want simple performance insights plus event analytics without a large vendor dependency.

Reveal is another Expo-native tool that offers performance monitoring with a focus on visual session replays. It captures screen-by-screen performance and user interactions, letting you watch recorded sessions to see where delays occur. It integrates with EAS Build and Update, similar to EAS Observe, but adds a qualitative layer—seeing actual user behavior—which helps debug UX issues that metrics alone miss.
