In their own words
Javadoc
Javadoc creates HTML API documentation from Java source files and is installed with the Java Development Kit (JDK). Its standard doclet describes public and protected Java types and members, including classes, interfaces, constructors, methods, and fields. It can process packages, individual source files, or both, with an option to include subpackages recursively. Alternate doclets can change the content and format of the generated output, while taglets add support for custom tags in documentation comments. The standard doclet includes DocLint to help identify common comment problems, but DocLint does not check conformance or repair errors. Oracle cautions that generated output may pose issues if it is non-conformant or contains executable content such as JavaScript. JDK 25 downloads are listed for Linux, macOS, and Windows. JDK 25 binaries are free under Oracle No-Fee Terms and Conditions through September 2028; later updates use a license that may require fees for production use beyond limited free grants.
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.
