Apidog review

Apidog takes second place because it gives small teams a design-first workflow and real test automation for less than most rivals. The free plan covers up to 4 users with all core features: a visual OpenAPI designer, the API client, mocking, unlimited test and collection runs, basic documentation and real-time collaboration. Test scenarios support flow control such as conditions and loops, test data, and SQL database operations, which suits QA teams that need to check data as well as responses. The client handles HTTP, GraphQL, gRPC, SOAP, WebSocket, Socket.io, SSE and MCP. Basic at $9 per user a month billed yearly removes the user cap and adds NoSQL databases and 90 days of change history. Professional at $18 adds team shared variables and calls through a self-hosted proxy, and Enterprise at $27 adds SAML SSO, SCIM and audit logs. A self-hosted Enterprise On-premises edition is sold through sales.
