Description
Add, modify, or remove HTTP request/response headers per URL, and clear cookies for the current site. No telemetry, no remote code. Badam HeadMod is a lightweight, fully transparent header-modification tool for developers, QA engineers, and anyone who needs to test how a site behaves under different requests — without installing a closed-source extension of unknown provenance. WHAT IT DOES Every rule you create is applied locally by Chrome's own declarativeNetRequest engine — this extension never proxies, logs, or transmits your browsing traffic anywhere. There is no analytics, no telemetry, and no remotely-loaded code; everything you can see in the popup and options page is everything the extension does. FEATURES - Add, modify, append, or remove any request or response header, scoped to a URL pattern or applied everywhere - One-click checklist of the actual request headers sent for the current page, so you can remove any of them and reload instantly - Keep JavaScript's navigator.userAgent and navigator.userAgentData in sync with a User-Agent header rule, so a page's JS and its network requests always agree - An optional strict mode (chrome.debugger) for a zero-race User-Agent override, for pages that check navigator.userAgent before the page has fully loaded - View and clear cookies for the current site with one click, or clear cookies across all sites from the options page - Export and import your rule set as JSON for backup or to move between machines - A single master switch to disable every rule at once without deleting them WHY IT'S DIFFERENT No bundler, no minified blob, no third-party dependency — the entire source is plain, readable JavaScript and HTML. Permissions are scoped to exactly what each feature needs, and each one is explained in this listing's permission justifications.
