Mock any endpoint

Create API mocks intuitively using the Insomnia application with support for custom endpoints using any HTTP Archive (HAR) response object, all standard HTTP methods, and method overriding.

placeholder

JSON, XML, YAML, HTML + CORS

Insomnia supports output in JSON, YAML, and XML, as well as an HTML view for in-browser testing. Insomnia dynamically generates Cross-Origin headers to debug your front-end JavaScript HTTP calls from any domain.

placeholder

From OpenAPI to API Mock

Simplify the creation of API mocks. Upload your OpenAPI specification and let Insomnia do the work for you by autogenerating API mocks for each route in the specification.

placeholder

Cloud hosting and collaboration

Keep your API mocks private. Or allow your collaborators to access them instantly in the cloud without needing access to your machine to support coordination between frontend and backend developers.

placeholder

Log and inspect calls

Log and inspect incoming calls to your custom endpoints by preserving the full history of requests that your API mocks are receiving. Identify client errors before they happen in production.
