The short version

  • Each has a real cost: Doxygen there is no vendor or paid support contract; when something breaks in a large or unusual codebase, the only recourse is community mailing lists, forums or reading the source; WordPress self-hosted installation requires PHP 8.3 and MySQL 8.0 or MariaDB 10.11 minimum; older versions expose security vulnerabilities
  • They diverge on capability: Doxygen covers Code comment parsing, WordPress covers Content management.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

  • An internal platform team documenting a large C++ or Java codebase where structure like class hierarchies and call graphs matters more than prosenot WordPress
  • A project with no documentation budget that still needs professional-looking reference output without any licence costnot WordPress

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Doxygen

  • There is no vendor or paid support contract; when something breaks in a large or unusual codebase, the only recourse is community mailing lists, forums or reading the source
  • Default HTML output looks dated and requires a third-party theme such as Doxygen Awesome to look acceptable to a modern audience, which is extra setup work not included
  • It only generates reference documentation from code comments; it is not a narrative documentation tool, help centre or CCMS, so most teams need a separate tool for guides and tutorials
  • Comment syntax and configuration have a real learning curve, and inconsistent comment discipline across a team produces inconsistent or sparse output regardless of the tool
  • Multi-language support varies in depth; parsing quality for languages outside its C-family core (C++, C, C#, Objective-C) is generally weaker than for its primary targets
  • There is no built-in hosting, search analytics, or reader-facing help centre features, so publishing the generated docs anywhere usable still requires separate infrastructure

WordPress

  • Self-hosted installation requires PHP 8.3 and MySQL 8.0 or MariaDB 10.11 minimum; older versions expose security vulnerabilities
  • Requires web server (Apache or Nginx) setup and ongoing maintenance; not suitable for serverless deployment
  • HTTPS mandatory for all installations; HTTP-only setups are not supported
  • Self-hosting requires responsibility for security patches, backups, and server administration

Answered from the vendors’ own pages

Doxygen: Is Doxygen really free with no paid tier?

Yes, it is GPL-licensed open source software with no company selling licences or support contracts.

WordPress: Does WordPress charge licensing fees for using the software?

WordPress is free and open source software, meaning there are no licensing costs to download or use the platform itself.

Source
Doxygen: Does Doxygen write documentation for me?

No, it extracts and formats documentation from comments a developer has already written in the source code; it does not generate prose from uncommented code.

WordPress: What costs should I expect when running a WordPress site?

While WordPress software is free, you will typically need to pay separately for web hosting, domain registration, and optional premium themes or plugins. These costs are not part of WordPress itself but are provided by third-party services.

Source
Doxygen: Can it produce anything besides reference documentation?

It can render standalone markdown pages alongside the generated reference content, but it is not a general authoring or publishing platform.
