Interceptor

Run web clients without backends by mocking HTTP requests

Features & Capabilities

Interceptor is a Chrome extension designed to empower front-end developers by allowing them to mock HTTP requests directly within the browser. This tool eliminates the dependency on backend APIs during the development phase by enabling the user to define custom responses for specific URLs. Each time the browser makes a request, Interceptor returns the predefined mock data instead of reaching out to the server.

By using Interceptor, developers can seamlessly continue their work without waiting for backend endpoints to be available or updated. This streamlines front-end development workflows, supports faster prototyping, and enables easier testing with varied data sets. The extension's codebase and changelog are openly accessible on GitHub, ensuring community collaboration and transparency. For more details, visit the official GitHub repository and documentation to get started with running your web clients sans backend dependencies.

Is Interceptor Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Interceptor requires a lot of sensitive permissions. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Interceptor has earned a fairly good reputation and likely can be trusted.
