The record

Purpose: Blackfire provides monitoring, profiling, testing, alerting, recommendations, browser monitoring, and analytics for PHP and Python applications.
Profiling detail: Profiling provides function-call level metrics and identifies bottleneck root causes.
Metrics: The integrations page lists wall time, CPU, I/O, memory, per-function network usage, SQL requests, and HTTP requests as profiling dimensions for PHP and Python.
Deployment stages: Blackfire says it can analyze application performance in development, testing, staging, and production.
Language coverage: Blackfire supports PHP and Python profiling; continuous profiling is listed for PHP, Python, Go, Node.js, Ruby, Rust, and Java.
CI/CD: Blackfire can be added to testing pipelines and supports SDK and CI/CD integrations.
Security and privacy: The FAQ says Blackfire does not collect user session data, database data, or source code, and anonymizes SQL queries and HTTP calls before transmission unless the Debug add-on is used.
Compliance: Blackfire says it has SOC 2 Type 2 and PCI certifications; its HIPAA-compliant agent offering is available only through Upsun, and standalone use does not guarantee HIPAA compliance.
Limits: The pricing FAQ says regular usage should not exceed 1,000 profiles per day per user; the documentation also lists a limit of 350 builds per day per user.
Free trial: Blackfire says it does not provide a free trial and offers a demo environment; eligible students, schools, and universities can get a free Profiler subscription through GitHub Student Developer Pack.
Support: Basic compliance questions can be handled by the Blackfire support team via email.
