They observe & control their application's performance with Blackfire:

Stop firefighting!

Are you tired of constantly battling performance issues during critical moments?

Customer complaints about slow service and the relentless pressure to optimize can be overwhelming. These challenges disrupt operations and demoralize teams forced into a reactive stance.

Regain control over the performance of your applications by smoothly integrating Blackfire into your development and deployment workflows.

Maximize performance efficiency with real-time insights

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.

Live Monitoring in Production

From overall application health to code-level insights, get facts and figures on how your application performs in production.

Monitor server-side response time and memory usage. Drill-down and find bottlenecks in transactions and service calls (SQL, HTTP, queues,...).

Let Blackfire automatically profile key transactions and obtain unrivalled visibility in your code's behavior.

Get alerted when something goes wrong.

Deterministic profiling in production, development, test/staging

Blackfire's unique deterministic profiling technology for PHP and Python collects function-call-level metrics that let developers understand exactly how their code behaves.

Through time-sequence and behavioral visualizations, analyse how code consumes time, memory and network. Find slow SQL queries and HTTP requests.

Collect such metrics from your live production site, then reproduce measurements on local machines. Iterate and compare iterations to validate code changes.

Performance Testing

Scenario preview showing example tests

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, and 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.

Automated Testing Workflows

Synthetic User Monitoring, CI/CD integration, unit tests integration, not-so-much-testing-yet? We've got you covered.

Leverage Blackfire's flexbile profiling automations to run performance tests proactively, whenever needed. Use our open source crawler, scraper and tester, our SDKs and native integrations, or configure basic testing scenarios right from our web application.

Get comprehensive Build reports and notifications where and when it matters, from email to Slack, and GitHub, Bitbucket or Gitlab.

Actionable Insights

Observability is powerful when it lets development, Ops, and IT teams take action.

Rather than letting teams build and browse complex data charts, Blackfire points out precise issues in the application and suggests resolution options.

Better: It offers that information in production and proactively in development, testing, and staging throughout development iterations.

“ 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. ”
