Choose Apidog if

Small and mid-size engineering teams that want one spec-first tool for API design, debugging, testing, mocking and docs at a lower per-seat cost than Postman.

  • Free for up to four users; paid seats cost less than Postman
  • Imports Postman, Insomnia, OpenAPI, HAR, cURL and WSDL

Look elsewhere if: Companies whose main need is a polished public developer portal or strict design governance (ReadMe, Mintlify, Stoplight).

Choose Insomnia if

Developers who want a fast, local-first, open-source API client with Git-based collaboration.

  • Open-source core under the Apache 2.0 license
  • Local-first storage keeps sensitive requests off the cloud
  • Clean, fast interface that is lighter than Postman

Look elsewhere if: Teams that need a full API platform with published docs and broad workspace collaboration (Postman, Apidog, Stoplight).
