Skylight is a smart profiler for Ruby and Rails applications. It turns performance data into actionable insights, so you spend less time diagnosing and more time improving.

Skylight makes it easy to understand and act on your app’s performance data:

  • Rails Performance Reporting: Skylight visualizes all your app’s performance data in a way that makes it easy to understand and act on.
  • Sources Of Agony: Skylight sorts your endpoints by “agony” — a combination of popularity and response time — to show you which endpoints to improve for the biggest performance gains.
  • Endpoint Intelligence: Interact with Skylight’s endpoint data to understand the events that lead to slowdowns and how to prevent them in the future.
  • Communicate Improvements: Our weekly trends email distills your performance data into a beautiful, actionable report that helps you catch slowdowns before your customers do.

Try it yourself! Make friends with performance data, no credit card required.

Today, we released version 2.0 of the Skylight Agent. 2.0 doesn't introduce any new APIs, but we did rewrite the SQL Lexer to support more varieties of queries. We also spent a lot of time on internal refactoring and improved our error logging.
