About

Insomnia is a macOS application for API development. It supports working with HTTP and GraphQL APIs, with tools for API design, testing, debugging, and mocking.

  • Design and refine APIs from OpenAPI specifications, with previews as you work.
  • Create API mocks with manually configured responses or responses derived from collections, specifications, and other inputs.
  • Run collection tests with pre- and post-request scripting.
  • Work with API assets stored locally, in Git, or in the cloud; the product site also describes collaboration and synchronization options.

Install the insomnia@alpha cask with brew install --cask insomnia@alpha, then open Insomnia from Applications. This cask installs Insomnia.app. It requires macOS 12 or later and conflicts with the separate insomnia cask, so do not install both.

Install and uninstall

Homebrew installs the app in your Applications folder.

Install without Homebrew

Download the same file Homebrew uses: github.com/Kong/insomnia/releases/download/core%4013.3.1/Insomnia.Core-13.3.1.dmg

SHA-256 only checks that the download is complete; it is not a security certification. See the SHA-256 and download address

Uninstall command
$ brew uninstall --cask \insomnia@alpha

A regular uninstall removes the app and keeps its settings and caches.

Deep clean (optional)
$ brew uninstall --zap --cask \insomnia@alpha

--zap also deletes the settings, caches and other files listed in the Homebrew definition. They can include data shared with other apps and cannot be restored, and it does not guarantee that nothing is left.See which files are removed
