Yaak
The API client you'll actually enjoy

Yaak is a fast, offline-first API client for developers that supports multiple protocols, encrypted secrets, and Git-based data storage. It features an agent-friendly CLI, request chaining, authentication handling, and a clean UI designed to stay simple by default. It is open source and available for Mac, Windows, and Linux.
Yaak runs locally with encrypted secrets and zero telemetry, stores data as plain-text files compatible with Git, and provides a CLI and GUI for creating, managing, and sending API requests across multiple protocols.
