Better app performance

Blackfire Profiler automatically instruments your code to gather data about consumed server resources like memory, CPU time, and I/O. But Blackfire Profiler is more than figures; its interactive Callgraphs make it straightforward to find bottlenecks and improve performance. Moreover, profile comparisons let you understand the impact of your changes.

A Profiler that understands your stack

Blackfire achieves a new level of accuracy by aggregating several profile samples and getting rid of non relevant data. Get even deeper and review the interactions with your entire stack (SQL database engines, cache servers, …). Blackfire Profiler even detects common performance problems automatically and helps you fix them quickly.

Profiling has never been that easy

Profile a page at a mouse click thanks to the Blackfire web browser extension. Best of all, no need to change the code; instrumentation is automated.

Browse through the function calls and identify performance bottlenecks thanks to the Blackfire intuitive UI.

Evaluate the impact of code changes

The unique “Compare” feature allows you to compare two profiles and figure out the performance impact of changes brought to your application. This is made possible thanks to the permanent storage of past profiles.

Share your profiles with others

Make others aware of your profiling work, to gather their input… or receive their praises.
