Sales Enablement and Marketing Platform

« When we introduced Blackfire and started drawing some profiles on well-used calls, our developers eagerly started writing down hundreds of notes with possible improvements in our application stack. While other open source tools can also give some insight into the stackframes used in your application, Blackfire goes beyond this with a full insight on the database, file I/O, and CPU-bound operations, with a great UI that allows collaborating on measurements and findings. We immediately were able to identify root causes and understood our application stack better. Furthermore, with the continuous integration capabilities, we can avoid making the same mistakes twice. In a lot of simple ways, the return on investment is simply off the charts. »
