What Is Insomnia?

Insomnia is a popular open-source API client for designing, debugging, and testing REST and GraphQL APIs. It uses a v4 JSON export format for sharing workspaces, requests, and environment variables across teams, making it easy to collaborate on API development.

This is used for:

  • Team Onboarding: Generate an Insomnia workspace file so new team members have every API request pre-configured.
  • API Documentation: Convert a list of endpoint definitions into a shareable Insomnia collection.
  • Migration: Move from flat file documentation or another API client into Insomnia's structured workspace format.
