Complete React component render tracing
Capture every component render cycle, hook execution, and state update to pinpoint wasteful re-renders and performance bottlenecks in live traffic.
React Error and Performance Monitoring
Get complete visibility into your React errors and performance issues that are impacting your end user experience. Fix critical issues sooner with in depth data points that helps you in analyzing and resolving issues with great speed.
Challenges
Unlock granular visibility into React component rendering and real user journeys in production
React Router & navigation waterfalls
Track React Router transitions, Suspense boundaries, and lazy loading waterfalls to identify slow route changes and hydration delays.
Hook execution performance
Monitor useEffect, useState, useMemo, and custom hook execution times across real sessions to optimize dependency arrays and prevent stale closures.
React error boundary captures
Catch errors thrown in component trees, Suspense fallbacks, and concurrent rendering failures with full component stack traces and fiber node context.
Interaction to fiber reconciliation
Trace user clicks, form submissions, and keyboard events through React's synthetic event system to ReactDOM reconciliation delays.
Render-to-commit correlation
Link slow user interactions directly to specific component trees, concurrent features, and server-side rendering hydration mismatches.
React 18+ concurrent insights
Measure time-to-interactive under concurrent rendering, transitions, and useDeferredValue patterns across browser rendering engines.
Bundle & tree-shaking validation
Validate code splitting effectiveness and detect unused code paths through real user navigation patterns and bundle analysis.
Component Rendering and Reconciliation
- Measure component render frequency during real user interactions and correlate execution cost with actual DOM commit latency to understand rendering impact.
- Identify unnecessary re-renders caused by prop changes, state updates, memoization gaps, or parent component re-execution.
- Analyze React reconciliation timing in detail to isolate the exact contributors to rendering delays and slow updates.
- Detect render propagation across deep component trees that causes redundant updates, layout shifts, and UI instability.
State and Hook Execution
- Measure execution timing of useState, useReducer, context updates, and derived state during real user workflows.
- Identify repeated or cascading state updates that trigger unnecessary renders even after state has stabilized.
- Analyze useEffect, layout effects, and custom hook execution during mount and update phases to surface expensive logic.
- Detect dependency array misconfigurations or missing dependencies that cause repeated side-effect execution.
Asynchronous and Event Execution
- Track asynchronous operations from API calls, promises, background tasks, and event-driven workflows across the application.
- Measure the delay between async task completion and UI updates triggered by state changes to detect slow render paths.
- Identify concurrent async execution paths that compete for main thread time and block rendering or user interactions.
- Correlate async execution timing with responsiveness, visual stability, and perceived performance.
Routing and Code Splitting Execution
- Break down route transition timing across navigation handling, lazy-loaded components, data fetching, and render execution.
- Measure latency introduced by dynamic imports, bundle loading, and code splitting across different network conditions.
- Identify blocking operations that delay component mount or first paint during navigation flows.
- Correlate routing execution timing with workflow interruption, slow transitions, and interaction delays.

React performance monitoring collects in-depth metrics on each user-interaction and analyzes everything from page load events to HTTP requests to front-end application crashes.
Monitoring React apps helps you to pinpoint React issues, measure user experience with the key metrics provided and fix them as soon as possible.
In real-time monitoring, a small piece of code is injected into the application to collect metrics while it is in use.
The browser-based applications can be monitored by injecting a JavaScript code which tracks and detects the front-end performance issues along with the XHR requests.
It also provides you with in-depth front-end metrics which helps you in resolving the issues at a faster rate.
Atatus Real User Monitoring supports front-end frameworks such as JavaScript, AngularJS, Angular, React, Backbone, Ember, Vue, Ionic, Ionic2+ and Meteor.
Also, you can embed the JavaScript snippet in a web page inside the tag and monitor.
Yes, we collect the IP address of the browser client used by the user, which will be displayed in the users' information along with the page views, load time, error count and last seen of the user, respectively.
Yes, we do collect core web vitals metrics such as:
- First Contentful Paint (FCP)
- Last Contentful Paint (LCP)
- First Input Delay (FID)
- Cumulative Layout Shift (CLS)
- Time To First Byte (TTFB)
As part of Atatus Browser Monitoring, we have a Single Page Application (SPA) Monitoring feature that gives a 360-degree view of what customers are doing with single-page apps and AJAX-based apps.
The benefits of real-time monitoring of users are substantial.
- It provides actual end-user experiences
- Easily track high value pages
- RUM metrics can determine whether service level agreements (SLAs) are being met, and to determine how users interact with an application and how developers can simplify the user interface.
Compared to all other browser monitoring tools Atatus offers affordable pricing plans. Collaboration requires in any monitoring tool so we do not limit your capabilities by charging per user.
We collect all the data points including Spans and Traces that are necessary for you without the need for you to select which to retain. With this you can easily monitor your entire application.
Rather than stop collecting the front-end performance metrics, our sales team will contact you to discuss the requirements.
Start free and send your first trace with OpenTelemetry or the Atatus agents. APM, logs, RUM, infrastructure and SIEM, all on one timeline.
