Apidog vs SwaggerHub

Apidog is an all-in-one API development platform that puts design, debugging, testing, mocking and documentation in one tool, so a team works from a single OpenAPI-based source of truth instead of passing specs between Swagger, Postman and a docs site. It runs in the browser and as desktop apps for macOS, Windows and Linux, and it markets itself directly as a cheaper Postman alternative.

Designers build endpoints and JSON Schemas in a visual editor; developers send requests over HTTP, GraphQL, gRPC, WebSocket, SOAP and SSE with Postman-compatible scripts; QA builds visual test scenarios, scheduled runs and performance tests; schema-driven mocks need no code; and interactive docs publish with custom domains. Sprint branches, Git connection, a CLI for CI/CD and self-hosted runners round it out. The free plan covers up to four users; Basic, Professional and Enterprise are billed per member, and documentation readers are free.

It fits teams that want to replace Postman plus a separate docs and mock tool. Stoplight and Redocly are stronger for pure design governance, ReadMe and Mintlify produce more polished public developer portals, and Postman has the larger ecosystem. Apidog's mock and docs features are less mature for large public API programs.

Recent releases focus on AI: an MCP server that feeds API specs to Cursor and other AI editors, an MCP client and AI agent debugger, AI test case generation and schema compliance checks. Apidog also offers an EU data region and an on-premises edition. Import a Postman collection during the 14-day trial to compare.

SwaggerHub is SmartBear's commercial platform for designing, governing and documenting APIs with the OpenAPI and AsyncAPI specifications. SmartBear, based in Somerville, Massachusetts, took over the Swagger project in 2015 and donated the specification to the OpenAPI Initiative; SwaggerHub is the hosted product built on the open-source Swagger Editor, UI and Codegen. In 2024 it was renamed API Hub and it is now sold simply as Swagger, with the design workspace called Swagger Studio.

The platform combines Studio (a collaborative editor with form-based editing, reusable domains, versioning and style-guide standardization), Portal (published API documentation), Contract Testing based on the Pact ecosystem, Functional Testing, Explore and a Catalog of all APIs. AI features generate or fix definitions from prompts or code, and an MCP server connects AI assistants. Plans are Individual, Team and Enterprise with published per-user prices, plus a quote-based Enterprise Plus; there is a free trial but no permanent free plan, since the open-source tools cover free use.

It fits API-first teams in mid-sized and large companies that need a single source of truth for many specs and enforced design rules. Stoplight offers a similar design-first workflow with a friendlier visual editor, Redocly is stronger for docs-as-code in Git, and ReadMe focuses on polished developer portals rather than design governance.

Buying tip: Portal Pro, Contract Testing Pro, Test Pro and SAML SSO are billed as add-ons, so price the add-ons you need before comparing with Stoplight or Redocly.
