Scout

Track down memory leaks, N+1s, slow code and more. For Ruby & Elixir apps. Starting at $0/mo.

Monitor app health

Track response times by tier (ActiveRecord, Redis, MongoDB, etc), throughput, queue time, error rates, and more with zero configuration.

Database Query Analysis

Scout hunts down expensive N+1 queries, tracks the number of ActiveRecord rows returned, and compares slow queries against their performance in faster requests.

Memory leak detection

Scout continually monitors your app for requests that trigger large memory increases and pinpoints memory hotspots in your code.

Github CodeView

Go beyond backtraces - with Scout’s Github integration, view relevant slow lines of code, authors, and commit dates inline with your slow transaction traces.

What are folks saying about Scout?
  • “Scout is a lifesaver. We had a launch where memory leak issues quickly cropped up and started causing problems. We started using Scout to figure it out.” - Chris @ Aptitude
  • “Scout helped us quickly root out and annihilate memory bloat in our app.” - Matt @ MAPC
  • “Forgot Stackprof, Bullet, or rack-mini-profiler - Scout will tell you - in production - exactly what endpoints and sql queries are consistently slow, and why.” - Ty Rauber @ The Outbound
  • “Scout is the first tool that dives right to the line-of-code of performance problems.” - Santiago @ Timp
