About

Send requests to REST, GraphQL, gRPC, WebSocket and Server-Sent Events APIs from one desktop app. Import collections from Postman, Insomnia, OpenAPI, Swagger or curl, group requests into workspaces and folders, and switch between dev, staging and prod with environment variables.

Yaak is offline-first, with no telemetry and no cloud lock-in. Authenticate with OAuth 2.0, JWT or Basic Auth, and keep secrets in your OS keychain. Workspaces can mirror to the filesystem for Git. Filter responses with JSONPath or XPath, and extend it with plugins and themes.

Highlights

  • REST, GraphQL, gRPC, WebSocket and SSE
  • Imports Postman, Insomnia, OpenAPI, curl
  • Secrets stored in your OS keychain
