Skylight is the smart Rails profiler you've been waiting for. It runs in the background of your app, analyzing the data and finding ways to improve speed and performance.
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.
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.
When Skylight detects the common mistakes that will slow your apps down, it will mark the endpoints with a Heads-Up, letting you know where the low-hanging fruit is so you know what to target.
