Apidog vs Mockoon

Apidog is an API platform for designing, debugging, mocking, testing, and documenting APIs, with GraphQL and SOAP support. Its specification-led workflow can generate request parameters, body content, and mock data, then check responses against specifications. For automated testing, users can arrange request sequences, add assertions, extract variables, and save requests as endpoint cases. It imports Postman data and supports Postman scripts. Database operations include MySQL, SQL Server, PostgreSQL, and Oracle on Free; ClickHouse, MongoDB, and Redis are listed for paid tiers. The CLI can connect to Jenkins, GitHub, and GitLab, and activity notifications can go to Slack or webhook-compatible tools. Deployment choices include Global and Europe SaaS services and an on-premises option hosted on customer servers. Apidog says desktop requests travel directly from the user's computer to the target server, not through Apidog servers. The free plan is time-unlimited for four users; paid plans start at $9/user/mo (annual), with a 14-day trial.

Mockoon is a free, open-source tool for designing and running mock APIs locally. It supports OpenAPI and can fit into existing applications and API design workflows. Mock behavior can use dynamic templating, rule matching, JSON databases, proxy mode, webhooks, and TLS. The tool can record requests and responses from a real API to create mocks, and it supports proxying and integration testing. The open-source version permits unlimited mock APIs and routes, including parallel runs. Its CLI can run mocks in headless automated environments such as CI, GitHub Actions, and Docker; mocks can also run in serverless environments including AWS Lambda and GCP/Firebase Functions. The desktop app stores mocks locally, works offline without an account, and reports that mock content and request data are not sent to Mockoon. Pro adds real-time team collaboration, synchronized mocks, and deployment management on private infrastructure; it can be self-hosted on-premises, in a private cloud, or on isolated or air-gapped networks. Team is listed at €10 a month, billed annually at €120/license/year, tax excluded. Eligible companies can request one 14-day self-hosted Pro trial with five license slots using a verified work email, without a payment method.
