Only what the record supports. Each point below is a figure on the Doxygen entry measured against the tools listed beside it.
There is only one tier
Doxygen publishes a single plan, Doxygen at Free. There is no smaller tier to drop to if the fit is wrong or the budget moves.
What each alternative does differently

Cheaper ways to solve the same problem
What you would be giving up
Doxygen is most often brought in 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. Anything replacing it has to cover the ones you actually depend on, and a cheaper tool that misses one of them is not cheaper.
Two things this page cannot settle. It compares on price, model, tier count and rating, because those are the fields the category listing carries, feature-level differences need both full records, which is what the head-to-head pages load. And the ratings are third-party aggregates imported with each entry rather than reviews written here, so a 0.2 difference between two tools is noise rather than a finding.
If Doxygen is broadly right and the question is cost, the Doxygen pricing breakdown covers every tier and what each one adds. If you want the whole field rather than a shortlist, the Documentation category lists everything the directory holds, and best documentation tools ranks them.
Doxygen runs on linux, macos, windows. Platform coverage is not carried on the category listing for the alternatives, so it is one more thing to check on each head-to-head page rather than here.

- No. It covers what this directory holds in the Documentation category, 19 tools beside Doxygen. The category page lists the rest of the catalogue as it grows.
