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.
YourKit .NET Profiler
YourKit.NET Profiler analyzes CPU performance and memory use in.NET and.NET Core applications. It can profile servers, Windows services, and other.NET applications locally or remotely in development, testing, and production. CPU results appear as call trees or hot spots; memory tools visualize the object heap and object graph. Plugins integrate with Microsoft Visual Studio and JetBrains Rider. The profiler shows slow SQL queries and ASPX requests and supports MongoDB and Cassandra. More than 20 inspections can identify duplicated objects, unclosed database connections, inefficient collections, and I/O operations. Remote profiling can create an SSH tunnel to an application on another machine. A.NET API manages profiling modes and captures snapshots, while command-line tools can automate profiling and performance monitoring in continuous integration. Version 2026.9 supports.NET 5 through.NET 10 and.NET Framework 4.x, with Linux, macOS, and Windows downloads. A single-seat annual subscription costs $99 a year; a perpetual single-seat license costs $129 as a one-time purchase. A 15-day trial is listed, and qualifying open source project contributors and Microsoft MVPs can contact sales regarding a free license.
