Scout saves you time by highlighting performance problems, filtering out noise, and eliminating guess work.
Scout automatically tracks and surfaces N+1 database queries, sources of memory bloat, and performance abnormalities for Ruby/Rails, Python/Django, and Elixir. PHP and Node are reportedly on the way.
Super easy to install in Heroku and works amazing out of the box.
Add-ons are extra, otherwise a really nice price point.
