What you would be giving up
Swagger UI is most often brought in for publishing api documentation that stays in step with the specification, letting developers try endpoints before writing any client code, internal api discovery across teams. 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 Swagger UI is broadly right and the question is cost, the Swagger UI pricing breakdown covers every tier and what each one adds. If you want the whole field rather than a shortlist, the Developer Tools category lists everything the directory holds, and best developer tools tools ranks them.
Swagger UI runs on web, self-hosted, docker. 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.
