Introduction

Apidog combines API design, an API client, mocking, automated testing and documentation in one product, positioned as an alternative to using several separate tools. Its pricing page lists client support for HTTP, GraphQL, gRPC, SOAP, WebSocket, Socket.io, MCP and SSE.

For testing, Apidog offers test scenario orchestration with flow control (conditions and loops), test data, response auto-validation against the API spec, local performance tests, and an Apidog CLI for running tests in CI. Its design side includes a visual OpenAPI and JSON Schema designer, and mocking covers smart mocks, expectations and scripts.

It runs as desktop apps (Windows, Mac, Linux), web apps and a browser extension, with real-time collaboration and an on-premises option for enterprises.

In the quality loop it spans design-time contract work and API test automation.
