Is Doxygen or GitHub better?

Neither clearly leads. Doxygen starts at Free and GitHub at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.

Which is cheaper, Doxygen or GitHub?

Doxygen starts at Free and GitHub at Free.

Does Doxygen or GitHub run on more platforms?

Doxygen runs on Linux, macOS, Windows. GitHub runs on Web, Desktop, Mobile.

Can I use Doxygen for free?

Both have a free tier, so you can try either at no cost before committing.

What is Doxygen best used for?

Doxygen is most often used for an engineering team generating api reference documentation directly from source code comments as part of a ci build, a library or sdk maintainer who wants reference docs that cannot drift out of sync with the code because they are generated from it, an internal platform team documenting a large c++ or java codebase where structure like class hierarchies and call graphs matters more than prose, a project with no documentation budget that still needs professional-looking reference output without any licence cost. Of those, an engineering team generating api reference documentation directly from source code comments as part of a ci build and a library or sdk maintainer who wants reference docs that cannot drift out of sync with the code because they are generated from it are not what GitHub is typically brought in for.

What can Doxygen do that GitHub cannot?

Doxygen covers Code comment parsing, Multi-format output, Call and inheritance graphs, Markdown support. GitHub covers Git repositories, Pull requests, Code review, Issues & projects.

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; GitHub acquired by Microsoft in 2018, reducing pure independence despite operational autonomy
They diverge on capability: Doxygen covers Code comment parsing, GitHub covers Git repositories.

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

GitHub

Acquired by Microsoft in 2018, reducing pure independence despite operational autonomy
Primary focus on source control differs from purpose-built project management tools like Jira
Pricing for enterprise features and private repositories adds up compared to some self-hosted alternatives

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.

GitHub: What is a Git repository and how does GitHub use it?

A repository is the centralized database that stores the complete collection of files and folders for a codebase, along with the revision history. GitHub uses Git to provide distributed version control access to repositories with version tracking, branching, and collaboration features.

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.

GitHub: How does GitHub authentication work?

When you connect to a GitHub repository from Git, you need to authenticate with GitHub using either HTTPS or SSH. GitHub supports multiple authentication methods including passwords, personal access tokens, SSH keys, and GitHub Apps.

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.

GitHub: How long has GitHub been operating?

GitHub was founded in 2008 and launched publicly on April 10, 2008, making it the dominant git hosting platform for nearly two decades.

Source

GitHub: Who owns GitHub and when did the acquisition occur?

Microsoft acquired GitHub for $7.5 billion USD, with the deal announced June 4, 2018 and completed October 26, 2018. GitHub operates as an independent subsidiary within Microsoft.
