The short version

  • Only Swagger has a free tier, so it costs nothing to try first.

  • They diverge on capability: Redocly covers OpenAPI reference docs, Swagger covers API Specification.
  • Prices and features above were last checked on 30 August 2026.

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

Redocly

  • Only as useful as your commitment to OpenAPI; teams without a maintained spec get little from it
  • The portal and governance features are paid, while the open-source renderer covers only reference rendering
  • Linting rules are another thing to configure and argue about before value appears
  • Narrower than a general documentation platform, by design

Swagger

  • Specific pricing details not published on main website; requires accessing pricing page or contacting sales

Answered from the vendors’ own pages

Redocly: Is Redocly free?

The Redoc renderer and CLI are open source and free. The developer portal and governance features are paid, with pricing published on the vendor site.

Swagger: How much does Swagger cost?

Swagger does not publish specific pricing details on its main website. A free tier is available with a Start Free Trial option. For detailed pricing information, users must visit the dedicated pricing page or contact Swagger sales directly.

Redocly: What does the linter do?

It enforces rules on the OpenAPI spec itself in CI — missing descriptions, naming, examples — so a poor spec fails the build rather than becoming poor documentation.

Swagger: Does Swagger offer a free plan?

Yes, Swagger offers a free tier described as simple, useful, and easy to master for API client functionality. Exact feature details and limitations are not specified on the homepage.

Source
Redocly: Do I need OpenAPI to use it?

Effectively yes. Without a maintained specification there is little for it to work with.
