New Relic, AppDynamics, and Dynatrace are three prominent Application Performance Monitoring (APM) tools that cater to different organizational needs, offering varied strengths in user experience monitoring, installation, and integration. New Relic, serving over 15,000 clients, is ideal for medium-sized cloud-based organizations due to its intuitive dashboard and transparent pricing, though it lacks an on-premise solution and is noted for its high cost. AppDynamics, owned by Cisco, targets large enterprises with its rich feature set and extensive technology stack support, but users have criticized its support and resource requirements, along with higher pricing. Dynatrace excels in ease of installation, security, and performance visibility, making it suitable for small to medium-sized businesses, although it requires extra configuration and is perceived as having high pricing. The choice between these tools typically depends on specific organizational needs, with Dynatrace favored for enterprises and New Relic for more cloud-based setups.
