About

Yaak Beta is the beta release of Yaak, a desktop client for interacting with APIs. The official product site describes support for REST, GraphQL, WebSocket, gRPC, and SSE; the Homebrew cask identifies the app as a REST, GraphQL, and gRPC client. This entry covers the beta cask, not the separate stable yaak cask.

  • Work with API requests in a desktop app; the product site also describes an agent-friendly CLI, but this cask installs the app artifact.
  • The product site says requests are stored locally and can be managed through Git workflows, including committing and comparing changes.
  • The site describes request chaining, value reuse, and inspection of redirects and headers.
  • The site lists plugins for extending authentication, importers, and template functions.

Install with brew install --cask yaak@beta. The cask requires macOS 13 or later and installs Yaak.app in /Applications. The beta cask conflicts with the stable yaak cask, so they cannot be installed side by side through Homebrew. The product site describes local-first operation, but its broader statements about the product should not be taken to mean that every listed capability is exclusive to, or guaranteed in, this beta build.
