Rehead – Modify HTTP Headers

Add, change or remove HTTP request headers with profiles. No account, no ads, no tracking. Access only to the sites you choose.

Rehead adds, changes or removes the HTTP headers of the requests your browser sends, grouped into profiles you switch on in one click. A header editor built for web developers, QA testers and API work. Why Rehead • Private by design: no account, no ads, no tracking, no analytics. Your headers and tokens stay on your device. • Access only to the sites you choose: at install, Rehead cannot see any website. It asks for access site by site when you add a domain to a profile. • Imports profiles exported from ModHeader (JSON), with a clear report of what was converted. Free features • Up to 3 profiles, one active at a time • Request headers: set, append or remove, as many as you need • Filters: target and excluded domains, initiating pages, resource types, HTTP methods, URL regular expressions • Global pause switch and a counter of modified requests on the toolbar icon • Live validation: invalid header names and values are flagged before anything is sent • JSON import and export Pro features • Unlimited profiles, several active at once (the last one turned on wins) • Response headers, for CORS testing or Content-Security-Policy work • Profiles limited to a single tab • Automatic turn-off after 15 minutes to 8 hours, handy for the Authorization header and cookies Common uses: send a bearer token to your API, change the user agent to test a mobile site, API testing, switch Accept-Language, set feature flags or X-Forwarded-For, right next to your developer tools. Pricing: the free version has no time limit. Rehead Pro costs €2.99 a month, €19 a year or €39 for life, paid on the secure checkout of Polar, our reseller. Rehead relies on the browser's declarativeNetRequest rule engine: the browser applies the changes itself, and the extension never reads your pages or your requests.
