Blackfire.io is a software as a service (SaaS) performance management solution. With their service, you can quickly identify bottlenecks in your PHP applications stack and resolve them.
Blackfire.io also supports continuous performance testing, allowing you to write performance tests and integrate with your continuous integration services.
When it comes to Drupal, this can allow you to find resource heavy hooks, or uncached Views.
Blackfire.io is not a replacement for an Application Performance Monitoring (APM) solution like New Relic, but provides a more direct complimentary service that allows you to discover performance problems before they begin.
