Overview

Yaak is a desktop API client for Mac, Windows and Linux that sends HTTP, GraphQL, gRPC, WebSocket and SSE requests in one workspace. It works offline with no account, storing requests and history on the device and encrypting secrets with ChaCha20-Poly1305. Data can optionally be stored as plain text for Git sync, and a CLI and MCP server let agents create and send requests.

Best for: Developers wanting an offline, local-first API client with Git-based sharing and a CLI for agents.
Pricing: Free for personal use; commercial use needs a licence at $79/year for Individual or $149/user/year for Business, after a 30-day trial.
Runs on: WebmacOSWindowsLinuxCLI
