Performance Insights for Developers

Find the source of real user pain — from long screen loads to rage clicking on broken buttons — with production data presented in a logical workflow. Identify your biggest opportunities for performance improvement with web vitals and understand how resource loading affects browser performance.

Trace slow-loading pages all the way back to poor-performing API calls — and surface any related errors — to get to root cause faster.

Go from a SQL query directly to the source code causing your database problems. Then, profile your code to see the performance bottleneck down to the function level.

Sentry Performance lets us keep an eye on slow requests and we’ve cut search latency by between 20-30%.
