What JProfiler is

JProfiler is a desktop application for Java and Kotlin applications on the JVM. It analyzes JVM data to help locate performance bottlenecks, memory leaks, slow JDBC queries, and costly HTTP calls. Its tools cover CPU and memory profiling, heap and thread analysis, and garbage collection. High-level probes provide visibility into JDBC, JPA, MongoDB, and Kafka operations; it also profiles incoming and outgoing HTTP calls and supports Spring and JEE components.

Users can compare snapshots, analyze JFR recordings, and automate offline recording with triggers or an API. Documented IDE integrations include IntelliJ IDEA, Eclipse, NetBeans, and VS Code. JProfiler supports profiling JVMs in Kubernetes and Docker, and can connect to remote JVMs using SSH credentials 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, although cloud AI agents may send retrieved data to their provider. A local MCP server can expose profiling data to configured AI coding agents, and its AI probe captures calls to LLM frameworks including LangChain4j and Spring AI. The product has a free evaluation license with restrictions. Its perpetual single license costs $549, paid once.

Who it suits

JProfiler suits Java and Kotlin developers investigating JVM performance, memory, database, messaging, or HTTP behavior. It is also relevant for teams that need remote or container profiling, IDE integrations, snapshot comparison, or automated recordings.

What it does well

  • Profiles CPU, memory, heaps, threads, and garbage collection.
  • Provides probes for JDBC, JPA, MongoDB, and Kafka operations.
  • Connects to remote JVMs over SSH without remote installation or agent deployment.
  • Supports profiling JVMs in Kubernetes and Docker.
  • Perpetual single license is available for $549, paid once.

What to know first

  • There is no free plan.
  • The free evaluation license has restrictions such as timeouts or evaluation warnings.
  • The Linux installer and UI require JDK 25.
  • Floating licenses limit concurrent use by the number of licenses.

Limits

The free evaluation license has restrictions, which can include timeouts, restricted use, or evaluation warnings. The Linux installer and UI require JDK 25.

As ej-technologies.com lists them, read 30 Sept 2026. The maker's own page has the final word.

Getting started

  1. Visit https://www.ej-technologies.com/jprofiler.
  2. Download the package for Windows, macOS, or Linux.
  3. For the Linux installer and UI, have JDK 25 available.
  4. Use the free evaluation license or select a perpetual license.
  5. Connect to a JVM locally or remotely using SSH credentials, or profile JVMs in Kubernetes or Docker.

Verdict

Choose JProfiler if you need detailed JVM profiling across CPU, memory, database, HTTP, or container workloads, with remote connections and IDE integrations. Look elsewhere if you need a free plan or cannot meet the JDK 25 requirement for the Linux installer and UI.
