Swagger UI FAQ

Common questions about Swagger UI, answered from independent, dated evidence.

What is Swagger UI?

Swagger UI is a web-based tool that automatically generates interactive API documentation from OpenAPI definitions. It enables developers to visualize, test, and explore APIs with real-time validation and supports collaboration across teams through version control integration. It is indexed under API Development Tools.

Source: https://swagger.io/tools/swagger-ui/

Is Swagger UI free?

Swagger UI offers a free tier, so you can start without paying. Paid plans start at €21.20 per user per month. Prices are published openly on the vendor's own pricing page. Pricing changes often, so verify at source before relying on it.

Source: https://swagger.io/tools/swagger-ui/

What platforms does Swagger UI support?

We have confirmed browser-based access to Swagger UI. That is the extent of what we could verify from public sources, so it may well offer desktop or mobile clients we have not indexed.

Source: https://swagger.io/tools/swagger-ui/

Can Swagger UI be self-hosted?

Yes. Swagger UI can be deployed cloud / SaaS and self-hosted, so it does not have to run on the vendor's infrastructure.

Source: https://swagger.io/tools/swagger-ui/

What does Swagger UI integrate with?

We have confirmed 3 integrations for Swagger UI, including GitHub, GitLab and BitBucket. This is what we could verify from public sources, so the vendor may support others we have not indexed.

Source: https://swagger.io/tools/swagger-ui/

What security certifications does Swagger UI have?

We have independently confirmed SOC 2, HIPAA and GDPR for Swagger UI. Certifications we do not list are ones we have not been able to verify from public sources, which is not the same as Swagger UI not holding them. Always confirm compliance directly before you rely on it.

Source: https://swagger.io/tools/swagger-ui/

Is Swagger UI open source?

Yes. Swagger UI is published under the Apache-2.0 licence, a permissive licence that generally allows commercial use and modification. Licence terms can change between releases, so verify against the repository for the version you intend to use.

Source: https://github.com/swagger-api/swagger-ui

Where is Swagger UI available?

Swagger UI is available worldwide. Its primary markets are the United States, the EU and Australia. The vendor is headquartered in the United States.

The vioscaleAI score: one lens on the evidence

Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for Swagger UI, not the verdict.
