Don’t guess why your app is slow. Skylight tells you exactly how your app is spending its time where it matters most—in your production environment.
Skylight is a smart profiler for your Rails apps that visualizes request performance across all of your servers. It feels a little bit like magic.
Skylight looks at how your code is behaving in production, alerting you to improvements you can make before they become showstoppers.
Every month, we calculate the peak Requests Per Minute (RPM) handled by all of your apps running Skylight. Your first 10 RPM are free, and each additional 50 RPM is just $20.
Skylight's UI uses cutting edge technologies like Ember.js and D3. When you click on a data point in Skylight, you can really feel the difference. It’s snappy, responsive and, well, fun. (It has nothing to do with the hamster illustrated here; we just like hamsters.)
