Sentry Profiling now supports Browser JavaScript, React Native, and Ruby, enabling developers to identify performance bottlenecks in their production environment, pinpoint hot code paths, and optimize slowest parts of their code for better user experience. The new platform support broadens coverage to frontend, backend, and mobile applications, allowing developers to analyze sluggish load times, enhance frontend performance, and find root causes of performance issues across services. Sentry Profiling provides insights on slowest or most regressed functions in code, enabling developers to identify potential performance bottlenecks, prioritize optimizations, and fix regressions before users feel the impact. The feature complements Sentry Performance, allowing developers to gain code-level visibility into production performance, investigate transactions, and optimize compute resources for faster page loads and improved user experience.
