Profiling gives code-level insight into your application performance in a variety of environments, including in production. By periodically capturing information about the code running in your app during a performance transaction, Sentry’s Profiling tool helps pinpoint the exact functions in your code that are consuming excessive CPU and causing performance problems – whether it’s loading screen issues or stuttering scrolls for the frontend user, or heavy infrastructure costs on the backend – so you can take action and fix them quickly.

Profiling supports Browser JavaScript, Python, Node, PHP, Android, and iOS SDKs. Our PHP support includes Laravel and Symfony. Our mobile support is limited to native iOS (Swift and Objective-C only) and Android (Java and Kotlin only). Other platform support is coming soon.

Core performance monitoring functionality like Tracing gives you a high-level overview of your system’s performance, relying on transactions to tell you what is slow and to measure how long it takes. Profiling helps you understand why it’s slow at the code-level, pinpointing the exact file/line number causing the slow request.

Think of profiling as taking a magnifying glass to a transaction or span and seeing exactly what’s happening in the app while that transaction or span is captured. The additional context provided by a profile associated with a transaction can help you quickly debug and fix your performance issue.

You’ll first have to enable performance monitoring in your app (which takes just 5 lines of code). Profiling hooks into the existing performance transactions in your app so there is no additional work to integrate beyond just enabling profiling in the SDK configuration.

The cost of Profiling is based on a unit consumption model that allows customers to pay for only what they need. Please check out our pricing page for details.
