Yet Another REST Client

Yet Another REST Client (YARC) is a browser-based tool designed to help developers create, test, and debug RESTful APIs. It provides an intuitive interface for constructing HTTP requests, inspecting responses, and managing a library of reusable API calls. YARC is particularly useful during API development, integration testing, and troubleshooting network interactions.

Key Features

• Favorites Management: Save complete requests including headers, payload, and method for quick reuse. Import and export your favorites as files for sharing or backup. Your favorites are automatically synchronized across devices via your Google account, so you can access them from any machine without manual transfer.
• Request History: Automatically records all previous requests and their responses. You can review past interactions, re-run any request with a single click, and filter the history to focus on specific endpoints or methods. This is helpful for debugging intermittent issues or repeating a sequence of tests.
• Custom Headers: Select from a predefined list of common HTTP headers (e.g., Content-Type, Authorization) or create and save your own custom headers. This allows you to easily set up authentication tokens, content negotiation, or any other header required by your API.
• Syntax Highlighting: Responses are displayed with color-coded syntax highlighting for JSON, XML, HTML, and CSS. This makes it easier to read and analyze structured data directly in the browser.
• Request Timing: Each request shows the total time taken to complete, helping you identify slow endpoints or network bottlenecks during performance testing.
• HTTP Method Support: Includes all standard methods: GET, POST, PUT, DELETE, PATCH, HEAD, and OPTIONS. You can also define custom HTTP methods if your API uses non-standard verbs.
• HTTP Basic Authentication: Built-in support for Basic Auth, allowing you to test endpoints that require username/password credentials without manual header construction.
• Responsive Design & Dark Mode: The interface adapts to different screen sizes for use on various devices, and a dark mode option reduces eye strain during extended usage.
• 100% Free: No cost, no hidden charges, and no account required to use the core functionality.

YARC requires the 'Read and change all your data' permission to send requests to any domain. This permission is necessary for the extension to function across different websites; YARC does not access or store your personal data. The tool is ideal for developers who need a lightweight, always-available REST client without leaving the browser.
