New Relic and AppDynamics are quite similar and best in class. AppDynamics offers not only a cloud version but also on-premise installation. AppDynamics still uses Flash in parts of the UI, and the UI is more old-school but shows more data details. New Relic has a more polished UI, older parts are typical Rails pre-web 2.0 pages, newer parts are AJAX heavy modern. AppDynamics shows a map of all network components, New Relic map is quite new and more like an afterthought. Both use agents for several programming languages. All other alternatives have far worse offerings (either only good for one language, worse detail level, even bigger costs or just very outdated software) - incl two Thoma Bravo owned properties, Dell, MS, CA, etc

AppDynamics would have been one of the first SV IPO in 2017. How many SV tech IPOs will we actually see in 2017?
