No Trial, Documentation Didn't Work, Support not helpful! **Rating:** 0.0/5.0 stars **Reviewed by:** Abhiraj M. | Co Founder and Head of Customer Success, Small-Business (50 or fewer emp.) **Reviewed Date:** April 22, 2024 **What do you like best about Blackfire?** Nothing worked for me so didn't find anything useful. **What do you dislike about Blackfire?** 1. No trial so you have to pay without trying the software 2. Followed the documentation links but they didn't work 3. Asked support to cancel the account and refund since the software didn't work. Shared screenshots but they didn't refund anything. 4. Support tried to get it going but no help from support as well. **What problems is Blackfire solving and how is that benefiting you?** None for me. The data was never pushed to backfire. I couldn't profile most of the API(s). Poor support. ### 3. Worthless customer service **Rating:** 0.0/5.0 stars **Reviewed by:** Steven v. | President, Small-Business (50 or fewer emp.) **Reviewed Date:** November 23, 2020 **What do you like best about Blackfire?** It helped us find some code base improvement opportunities. **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. **Recommendations to others considering Blackfire:** Go with any alternative. There's even a few open source ones that would probably serve you better than this. **What problems is Blackfire solving and how is that benefiting you?** Explained this in 'dislikes' ### 4. Best PHP App Performance Software **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Online Media | Small-Business (50 or fewer emp.) **Reviewed Date:** November 13, 2018 **What do you like best about Blackfire?** I love the performance profiling. This is HUGE in my line of work so I can quickly identify Memory, Network Calls and SQL requests. AWESOME documentation and support. Robust API **What do you dislike about Blackfire?** Honestly I can't think of anything that I dislike about this product so far. **Recommendations to others considering Blackfire:** How many customers are you losing because your app / site takes too long to load? Can you pinpoint what exactly is going on? You need Blackfire **What problems is Blackfire solving and how is that benefiting you?** We are solving issues we were having before of our apps performance with blackfire. We are getting very detailed insights on why we were so slow and issues that took weeks to figure out are now on the fly and update real-time. Also the integrations with Magento, cPanel, Bitbucket, Slack and New Relic keeps everything in sync. - [View Blackfire pricing details and edition comparison](https://www.g2.com/products/blackfire/reviews?section=pricing&secure%5Bexpires_at%5D=2026-06-30+19%3A11%3A56+-0500&secure%5Bsession_id%5D=47dbc6a5-276e-4245-a5cb-010ea9981e70&secure%5Btoken%5D=700ae5eb21fcbcf14802a25229b372690e1806acd429beaa58b1b325051e9f20&format=llm_user) ## Blackfire Features **Monitoring** - Performance Baselines - Performance Analysis - Performance Monitoring - AI/ML Assistance - Multi-System Monitoring **Response** - Dashboards and Visualization - Incident Alerting - Root Cause Analysis (RCA) **Agentic AI - Application Performance Monitoring (APM)** - Autonomous Task Execution - Cross-system Integration - Adaptive Learning - Proactive Assistance - Decision Making **Performance** - Real User Monitoring (RUM) - Second by Second Metrics **Functionality** - Synthetic Monitoring - Dynamic Transaction Mapping - Load Balancing - Cloud Observability ## Top Blackfire Alternatives - [Dynatrace](https://www.g2.com/products/dynatrace/reviews) - 4.5/5.0 (1,231 reviews) - [LogicMonitor](https://www.g2.com/products/logicmonitor/reviews) - 4.5/5.0 (585 reviews) - [New Relic](https://www.g2.com/products/new-relic/reviews) - 4.4/5.0 (568 reviews)
