Mockoon is a free, open-source desktop application (built with Electron) for designing and running mock REST APIs locally, with a companion CLI for headless/CI environments. It supports OpenAPI import/export, JSON templating, proxy forwarding, request recording, CRUD routes, and a paid cloud tier for team collaboration.
Use cases
- mock a REST API locally while the backend is still in development
- run fake APIs in CI pipelines or Docker containers
- import an OpenAPI/Swagger spec and generate mock endpoints
- simulate error responses, latency, and edge cases for integration testing
- proxy and record real API responses to replay later
- self-host mock APIs with a CLI for frontend development
When to choose
- you need a GUI to quickly spin up mock REST servers without writing code
- you want local, offline API mocking with no account or remote deployment
- you need headless mocking in CI, Docker, or GitHub Actions via the CLI
- you work with OpenAPI specifications and want import/export support
When to avoid
- you need contract-testing tools like Pact with consumer-driven contracts
- you only need simple HTTP stubs inside unit tests where a code library like WireMock or nock fits better
- you require GraphQL or gRPC mocking rather than REST/WebSockets
- you need cloud-hosted mocks without paying for Mockoon Cloud
