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).

Choose Whiteboard if

Developers who let coding agents write large changes and want a visual, architecture-level way to review them.

  • Free and MIT-licensed, runs against local checkouts
  • Works with the coding agents teams already use
  • Reviews structure and decisions, not only changed lines

Look elsewhere if: Teams that need an editor or a full review workflow with approvals and comments (GitHub, Cursor).
