tweak: mock and modify HTTP requests

Mock or modify your HTTP requests to test, develop and demo your web application

tweak is a powerful Chrome extension enabling web developers to mock and modify HTTP requests directly within the browser. It allows interception of API calls where you can modify response data, headers, status codes, as well as request payloads and headers.

Key features include delaying requests, exporting/importing rules for easy team collaboration, and automatic background search for requests to import. The premium version offers advanced capabilities like custom JavaScript modifications, collections for workspace organization, bulk rule updates via global variables, mock data generation with random functions, and debugging tools with breakpoints and logpoints.

While tweak excels at manipulating HTTP requests, it does not replace document resources such as HTML, CSS, or images. It is an ideal tool to streamline testing, development, and demo workflows in modern web application projects.
