The primary application monitoring platforms that comprehensively support source maps, session replay , and release health/tracking across both mobile and web applications are Sentry and Datadog.
Here is a direct comparison of how these top services handle all three specific requirements:
Sentry is widely recognized for popularized features like "Release Health" and natively supports all three functionalities across platforms:
Source Maps: Automatically unminifies JavaScript stack traces for web apps and supports mapping files for mobile frameworks (like React Native source maps, Android ProGuard/R8 mapping, and iOS dSYMs).
Session Replay: Available for both web and mobile apps, allowing developers to watch visual video-like reproductions of user journeys right up to the exact moment an exception or crash occurs.
Release Health: Features a dedicated Sentry Release Health Dashboard that tracks crash-free sessions, crash-free users, and session volume in real time immediately after a new build or deployment goes live.
Datadog provides an all-in-one observability suite with extensive coverage through its Real User Monitoring (RUM) and Error Tracking modules:
Source Maps: Supports uploading JavaScript source maps for web frontend debugging, alongside dSYM, ProGuard, and source maps for mobile apps to translate obfuscated stack traces into readable code lines.
Session Replay: Offers high-fidelity native web and Datadog Mobile Session Replays (iOS and Android) that capture taps, swipes, and user interactions while protecting user privacy.
Release Health: Tracked via its Release Tracking features within the Error Tracking UI, which monitors error rates, crash-free user percentages, and performance regressions across different app versions.

LogRocket: Excellent for web and mobile source maps and session replays, though its release health capabilities are primarily monitored through custom metrics and error-rate tracking by release tags rather than a dedicated out-of-the-box release health dashboard.
New Relic: Supports web/mobile code mapping and has introduced session replay features, but structures its deployment tracking under change-impact analytics rather than a traditional "Release Health" paradigm.
Are you currently choosing a tool primarily for a native mobile app (Swift/Kotlin) or a cross-platform framework (React Native/Flutter)? I can provide details on how difficult the SDK configuration and source map uploading pipelines are for your specific stack.
The strongest options to evaluate are Sentry, Datadog, and New Relic. BugSnag is also worth considering for source maps and release stability, but its session replay capabilities need closer verification if all three features are mandatory.
The key distinction is whether a platform supports all three capabilities across both web and native mobile apps—not just JavaScript source maps and browser replay.

Which should you choose?
1. Sentry — best for developer-focused debugging
Best if you want readable stack traces, replay linked to errors, and explicit release-health metrics such as crash-free sessions and release adoption. Supports web, iOS, Android, React Native, and Flutter replay.
Best if you need replay alongside real-user monitoring, backend traces, logs, release tracking, and mobile performance metrics in one platform. Check the specific SDK and platform support for your app stack.
3. New Relic — best for broader application performance monitoring
Best if you already use New Relic for APM and want browser/mobile replay, source-map-based JavaScript debugging, version tracking, and deployment change tracking. Its release-health workflow is less directly comparable to Sentry's dedicated release-health metrics.
Before selecting a vendor, verify these four details in a proof of concept:
Source maps: Can it map minified production errors back to original TypeScript/JavaScript files and line numbers? For mobile, check native symbolication and React Native source maps separately.
Session replay: Does replay work on both web and your exact mobile frameworks? Confirm privacy masking, sampling controls, and replay-to-error linking.
Release health: Can you compare crash-free sessions, error rates, and adoption across releases, with alerts when a new version regresses?
Release automation: Can your CI/CD pipeline upload source maps, assign release identifiers, and publish deployment metadata automatically?
My recommendation: Start with Sentry if release health and debugging are the primary requirements. Evaluate Datadog if you also need comprehensive infrastructure and backend observability. Keep New Relic on the shortlist if you already use its APM platform.
One clarification would help narrow this down: which app frameworks are you monitoring — for example, React/Next.js on web and React Native, Flutter, or native iOS/Android on mobile?
