You can now sign up for Blackfire Profiler using GitHub and Google accounts.

Blackfire comes pre-installed on Heroku, Platform.sh, and fortrabbit containers; profiling is a click away on those platforms.

Composer got a huge performance boost last week thanks to the disabling of the garbage collector. Blackfire now displays a bunch of information about the PHP garbage collector calls to help you understand what’s going on in your PHP code.

We’ve been working hard on Blackfire Profiler for several months now. Participate in the public beta, try out this new generation of profiling tools, for free, and give us your feedback.
