RESTer is a powerful REST client Chrome extension designed for developers and testers to perform HTTP requests using any method, custom URLs, headers, and bodies. Users can save favorite requests, organize them into collections, and review a comprehensive history of both requests and responses. The extension supports various authentication methods, including Basic and OAuth2, and allows the use of placeholders and keyboard shortcuts for efficient workflow. RESTer ensures privacy by storing all data locally on the user's machine. It requires permissions to access and modify requests only within its own tabs to maintain user security and enhance functionality. Whether testing APIs or exploring web services, RESTer offers an intuitive and feature-rich interface to streamline your HTTP request management.
