Javadoc vs Palt

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.

Palt is a hosted API documentation platform for creating, publishing, and managing interactive reference material from OpenAPI specifications. Import OpenAPI or Swagger JSON and YAML files for OpenAPI 3.0 and later, then let readers try endpoints in a browser-based console. Palt also generates code samples in cURL, JavaScript, Python, Go, and more. A visual editor offers custom colors, fonts, dark mode, HTTP-method colors, and company logos; endpoint search includes keyboard shortcuts. Published documentation can use a custom domain or be embedded in an existing site. Custom domains are free and include automatic SSL. The Free plan costs nothing and includes 3 projects, a custom domain, the Try It playground, and basic analytics. Pro costs $19 a month per project and adds branding removal, custom CSS, advanced analytics, and priority support. Enterprise pricing is custom and includes SSO, audit logs, an SLA guarantee, and dedicated support. Palt says it does not store API keys or sensitive request data.
