Capabilities
What performance gives you
Performance and network monitoring for slow screens, failed APIs, and hangs — plus Core Web Vitals in the browser.
Core Web Vitals with the reason attached
LCP, INP, CLS, FCP and TTFB are collected automatically per route, each with attribution for what actually caused the measurement — so a regression comes with somewhere to look rather than just a worse number.
Page loads, route changes, and anything else you name
Page-load and route-transition transactions are instrumented for you. Where that is not enough, you can open your own transactions and spans around the work you care about.
Network monitoring in the same lane
Failed and slow requests are captured alongside the page timings rather than in a separate tool, so a slow screen and the API call behind it sit on one timeline.
