What Blackfire.io is
Blackfire.io is a cloud platform for monitoring, profiling, testing, alerting, recommendations, browser monitoring, and analytics for PHP and Python applications. Its profiling provides function-call-level metrics to help identify the causes of performance bottlenecks, including wall time, CPU, I/O, memory, network usage per function, SQL requests, and HTTP requests. Blackfire can analyze performance across development, testing, staging, and production, and can be added to testing pipelines through SDK and CI/CD integrations. It also lists hosting and configuration management integrations, plus notifications through webhooks, email, GitHub, and Slack. Continuous profiling is listed for PHP, Python, Go, Node.js, Ruby, Rust, and Java. Blackfire says it does not collect session data, database data, or source code, and anonymizes SQL queries and HTTP calls before transmission unless the Debug add-on is used. A free plan is available. The Development plan is €33.25 per month billed yearly; Production is €158.25 per month billed yearly or €189.90 monthly.
