In their own words
JProfiler
JProfiler is a desktop profiler for Java and Kotlin applications on the JVM. It helps locate performance bottlenecks, memory leaks, slow JDBC queries and costly HTTP calls. Its analysis covers CPU and memory use, heaps, threads and garbage collection, with high-level probes for JDBC, JPA, MongoDB and Kafka operations. HTTP profiling examines incoming and outgoing calls, and the product supports Spring and JEE components. Users can compare snapshots, inspect JFR recordings, and automate offline recording through triggers or an API. Documented IDE integrations include IntelliJ IDEA, Eclipse, NetBeans and VS Code. JProfiler can profile JVMs in Kubernetes and Docker and connect to remote JVMs through SSH without remote installation or agent deployment. It runs on the user's infrastructure and does not send profiling data to ej-technologies or third parties; cloud AI agents may send data they receive to their provider. A free evaluation license has restrictions. The perpetual single license costs $549 as a one-time purchase; other listed licenses include floating options and support-and-upgrade bundles.
