Swagger

API design and documentation platform for building, testing, and managing APIs

As of 30 August 2026, Swagger is free to use. Swagger (now OpenAPI) is an open-source framework for designing, building, and documenting RESTful APIs. Softwr lists it under APIs. Swagger is made by SmartBear Software, launched in 2011, available on Web, API, Windows, macOS.

Overview

What Swagger does

Swagger (now OpenAPI) is an open-source framework for designing, building, and documenting RESTful APIs. It provides tools for API specification, interactive documentation, and code generation with support for multiple programming languages.

What people use it for

  • API Development
  • API Gateway
  • API Testing
  • API Documentation
  • Microservices

The honest half

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Swagger.

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

Cross-shopped

What people choose instead of Swagger

Each pairing was judged by two reviewers asking whether a buyer would genuinely weigh the two against each other. The ones that failed were deleted rather than published.

Softwr does not host reviews and shows no star rating for Swagger, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it. Tell us if any of it is wrong.
