JProfiler vs VisualVM

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.

VisualVM is a free standalone tool for troubleshooting Java applications in development and production. It combines JDK command-line tools with monitoring for CPU use, garbage collection, heap and metaspace memory, loaded classes, and running threads. Sampling and instrumentation profilers help analyze performance and memory use. For diagnostics, it can capture thread dumps, browse heap dumps, analyze core dumps, and save application data for offline review. VisualVM can list remote Java applications when jstatd runs on the remote host, or connect to applications manually through JMX. Official and third-party plugins extend the tool, and a Security plugin provides a GUI for SSL/TLS settings. The site documents integrations or launchers for Eclipse, IntelliJ IDEA, and Visual Studio Code, plus a third-party NetBeans profiler. It runs on Windows, Linux, and macOS and is distributed as a ZIP archive and a macOS application bundle. The download page lists Oracle JDK and OpenJDK versions 8–26 and GraalVM versions 19–JDK 26. Some third-party plugins may not work after changes introduced in VisualVM 2.0.
