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.
Skylight’s new Environments feature allows users to easily enable Skylight’s smart performance profiling in multiple environments and effortlessly navigate between an app’s environments in the Skylight UI. Now available with the 3.0.0 agent.
Code Triage is an open source app built to help other open source projects. Popular open source projects receive a lot of bug reports, feature requests, and pull requests every day, and just reading through all of them can be a huge time sink for their maintainers.
Every single app — large or small, open source or not — has room for improvement when it comes to performance. This is why we created Skylight for Open Source to give open source contributors the tools they need to find these issues.
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.
