HTTP Headers is a lightweight, open-source Chrome extension designed for developers and curious users to quickly view HTTP headers of the current webpage. It lists all request and response headers alphabetically, truncates long header values for readability, and provides descriptions for common headers to enhance understanding.

The extension features a badge on its icon showing response status codes or total requests with color-coded status indicators. Users can copy any header to the clipboard with a click, making header inspection efficient and straightforward. No third-party libraries or tracking ensure privacy and performance.

Easy to use. Super useful when trying to figure out problems with http headers, e.g. cache control.

Very well coded extension. It helped me out when I was stuck in a rut and the default Web tools in Chrome were just not displaying the correct GET/POST data. I fiddled out for a long time in the builtin Inspect->Network but it just would not show the correct data. This tool displayed the correct and got me sorted immediately

Extension safety

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.

HTTP Headers requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Risk likelihood

Risk likelihood measures the probability that a Chrome extension may turn malicious. This is determined by the publisher and the Chrome extension reputation on Chrome Web Store, the amount of time the Chrome extension has been around, and other signals about the Chrome extension. 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 Chrome extension.

HTTP Headers has earned a good reputation and can be trusted.
