"Worthless customer service"
0/5
What do you like best about Blackfire?

It helped us find some code base improvement opportunities. Review collected by and hosted on G2.com.

What do you dislike about Blackfire?

- There is no explanation nor documentation as to what they define as a 'profile' - They count same API endpoint AND same method (e.g. POST, OPTIONS, GET etc) as different profiles - There's a max of 1000 profiles per day which is not mentioned anywhere on their pricing / feature pages (somewhere hidden in the faqs) - Their support is worthless. -- it is slow (takes various days for them to reply even AFTER they have seen the message) -- Halve-assed replies. When you ask 2 things they only reply to 1 -- They give halve answers totally not trying to solve the issue (or educate me) -- Their replies border on rude due super short (and very unhelpful) answers.
