What is there to say about ScoutAPM, it is a very friendly and always replies to queries promptly, the UI of the product is quite intuitive and in addition to that we were offered a demo in order to better understand how to best squeeze the most out of it. Definitely in the short amount of time that we've used it, it has already proven it's usefulness by giving us the opportunity to see part of the platform which were not performing up to the standard we expected, making it easier for us to make them better. I would definitely recommend ScoutAPM, as I did with my boss, to everyone who is willing to have a better understanding of what is happening under the hood even out of office hours. Hope this helps, have a nice day.

Scout's UI is intuitive, and the app provides the visibility we need into our Rails app's performance over time. Scout makes good use of modern web visualization tools to present data in ways that are easy to understand and interpret. A particularly valuable feature is the ability to compare performance from two different time periods of varying length. The alerts function lets us set up fine-grained notifications when certain metrics aren't in the ranges we like. This is really helpful. Scout's pricing is affordable for a small SAAS business like mine — the cost-benefit versus other providers of similar services is a slam-dunk.

Most APMs nominally support Rails. Not Scout. The autoinstrumentation showing exactly, line-by-line where slowdown is happening is second-to-none. The N+1 detection is amazing. Showing me exactly where we're punishing our DB, both on web & async workers, makes my life (and the lives of our operations team) much easier.
