## Install

Download Yaak for macOS, Windows, or Linux from [yaak.app/download](https://yaak.app/download). Package managers and other install methods are in the [installation docs](https://yaak.app/docs/getting-started/installation).

## Features

Yaak is an offline-first API client designed to stay out of your way while giving you everything you need when you need it.
Built with [Tauri](https://tauri.app), Rust, and React, it’s fast, lightweight, and private. No telemetry, no VC funding, and no cloud lock-in.

### 🌐 Work with any API

- Import collections from Postman, Insomnia, OpenAPI, Swagger, or Curl.
- Send requests via REST, GraphQL, gRPC, WebSocket, or Server-Sent Events.
- Filter and inspect responses with JSONPath or XPath.

### 🔐 Stay secure

- Use OAuth 2.0, JWT, Basic Auth, or custom plugins for authentication.
- Secure sensitive values with encrypted secrets.
- Store secrets in your OS keychain.

### ☁️ Organize & collaborate

- Group requests into workspaces and nested folders.
- Use environment variables to switch between dev, staging, and prod.
- Mirror workspaces to your filesystem for versioning in Git or syncing with Dropbox.

### 🧩 Extend & customize

- Insert dynamic values like UUIDs or timestamps with template tags.
- Pick from built-in themes or build your own.
- Create plugins to extend authentication, template tags, or the UI.
