Who is Yaak best for?
Yaak is best for backend developers who want an API client that saves requests in Git, not a vendor cloud.
API collections in Git
Each request, folder and environment is one YAML file, and the built-in Git UI branches, commits and diffs them.

It imports Postman collections and environments, Insomnia exports, Bruno collections, OpenAPI specs and curl commands.

Claude Code, Codex and Cursor can create and send the same requests through Yaak's CLI or MCP plugin.
