from your data.

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.


True Response Times

Skylight reports 95th percentile response times everywhere, giving you an accurate sense of what your customers are experiencing. It's performance data grounded in reality, not wishful thinking.

Featherweight Agent

Skylight's agent runs unobtrusively in the background, sipping rather than guzzling memory and CPU. So not only do you get better quality data, you get it without paying a performance penalty.


Every request, Skylight analyzes how your app is spending its time. When it detects common mistakes that make apps slower, Skylight will mark that endpoint with a Heads-Up, letting you know where the low-hanging fruit is.

Big Picture

You know your app is running slowly in production—but where is it actually spending all that time? Big Picture shows you where your app is getting bogged down, on a beautiful visual graph that makes bottlenecks immediately obvious.

Pay for what you use.

Ditch complicated plans and pushy salespeople. With Skylight, you only pay for what you use.

Pricing starts at $20 per month for the first million requests, with discounts that kick in automatically for high-volume customers. Simple.

Experience Awesome UI.

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.)
