Blackfire was born from the world of open-source software in the heart of Europe.
We saw engineering teams struggling with performance bottlenecks and drowning in observability data without answers. So we built a different kind of tool: one that delivers precise, actionable insights, helping developers stay in control of their applications, without the noise.
Today, Blackfire is the leading Web Observability solution in Europe for decoupled PHP and Python applications — trusted by over 1,000 engineering teams worldwide.
In 2021, we joined forces with Platform.sh, expanding our mission to provide 360° actionable observability. Together, we empower developers with the tools they need to build, scale, and optimize their applications confidently — with performance as a feature, not an afterthought.
Effortlessly identify and address performance bottlenecks, enhancing the efficiency of your application's most resource-intensive areas.
Achieve high performance with low overhead while maintaining full observability of your entire application.
Achieve instant bottleneck detection through continuous application monitoring and thorough code execution analysis.
From overall application health to code-level insights, get facts and figures about how your application performs in production.
Monitor server-side response time and memory usage. Drill-down and find bottlenecks in transactions and service calls (e.g., SQL, HTTP, queues).
Obtain unrivaled visibility in your code's behavior while Blackfire automatically profiles key transactions.
Receive an alert when something goes wrong.
Blackfire's unique deterministic profiling technology for PHP and Python collects function-call-level metrics that help you understand exactly how your code behaves.
Through time-sequence and behavioral visualizations, analyze how code consumes time, memory, and network. Find slow SQL queries and HTTP requests.
Collect these kinds of metrics from your live production site, then reproduce measurements on local machines. Iterate and compare iterations to validate code changes.
Performance is a feature. It should be tested as such.
Thanks to Blackfire's cutting-edge profiler, extend your test suite from unit-tests, integration tests, and functional tests to performance tests.
Never let a performance regression be deployed on production.
Benefit from our extended support of PHP, Symfony, Laravel, Magento, Drupal, Typo3, Wordpress, Python, Django, with built-in metrics and default assertions.
Synthetic user monitoring, CI/CD integration, unit tests integration? We've got you covered.
Leverage Blackfire's flexible profiling automations to run performance tests proactively, whenever needed. Use the open-source crawler, scraper and tester, SDKs, and native integrations, or configure basic testing scenarios right from the Blackfire web application.
Get comprehensive build reports and notifications where and when it matters—from email to Slack, and GitHub, Bitbucket, or GitLab.
“ Blackfire's continuous observability solution is empowering. Our teams can make early discoveries with the monitoring. Improvements in the code are based on the precise and detailed information collected while profiling parts of the applications. Then, by writing efficient performance tests and plugging them with our CI/CD pipeline, we avoid regressions of already-known performance issues. ”
