Javadoc vs pdoc

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.

pdoc generates API documentation from Python projects and organizes it around each project's module hierarchy. Its setup documentation says no configuration is needed to begin. The tool produces standalone HTML that can be exported to files, and a built-in web server refreshes the documentation when source files change. It supports Python type annotations and recognizes Markdown, numpydoc, and Google-style docstrings, with limited reStructuredText support. Developers can customize the generated HTML templates; search runs in the browser without third-party services. Deployment guidance covers GitHub Pages, and custom HTML fragments can be embedded in content management systems or static site generators. pdoc also offers a high-level interface and can be used as a Python library. It is free and open source, compatible with Python 3.10 and newer, and available for Linux, macOS, Windows, web, and self-hosted use. HTML is its only output format, and API documentation is its principal use case. Since pdoc imports or executes the Python modules while extracting docstrings, those modules are executed during documentation generation; Sphinx is recommended for substantially more complex documentation needs.
