Design APIs with Insomnia

Design and preview new APIs with OpenAPI

Using Insomnia, you can create or upload an API spec to a document.

Insomnia can help you write or edit your spec with the following:

  • View a generated preview of your spec in the right pane.
  • Automatically linted. Errors display at the bottom of the center pane and include error type, line number, and error message
  • View information about your spec in the left sidebar, such as servers, request body, and schemas.
  • Collaboratively create APIs with an unlimited number of contributors (free accounts allow unlimited contributors on one project) and git version control.
  • Generate code snippets automatically in over 12 different programming languages.
