Your application’s success depends on how quickly you find what’s slowing things down. Performance, Sentry’s client-side performance monitoring solution, gives your team the full-stack visibility it needs to iterate faster, take fewer risks, and ultimately, ship performant software.
With Performance, teams can trace slow-loading pages back to its API call as well as surface all related errors. Now Engineering Managers and Developers can resolve bottlenecks and deliver fast, reliable experiences that your customer demands.
More important than understanding that there’s been an error is understanding how your users have been impacted by that error. By gathering field data (variable network speed, browser, device, region) via Google’s Web Vitals, Performance helps you understand what’s happening at your user’s level. Now you know whether your users are suffering from slow loading times, seeing unexpected changes, or having trouble interacting with the page.
Trace poor-performing pages not only to its API call but to its children. Performance’s event detail waterfall visualizes your customer’s experience from beginning to end, all while connecting user device data to its expected operation.
With performance monitoring, you can view transactions by slowest duration time, related issues, or the number of users — all in one consolidated view. And release markers add another layer of context so your team can gauge how customers react to code recently pushed to production.
