HTTPatch

ExtensionDeveloper Tools

Overview

Free, ad-free modification of HTTP request & response headers. An open ModHeader alternative.

HTTPatch helps you test and customise HTTP headers in your browser. Set, append or remove request and response headers; group rules into named profiles; scope them by URL, resource type or browser tab; add Cookie, Set-Cookie and CSP rules with focused editors; pick popular header names from a searchable list or type your own; duplicate a rule; and pause all changes with one switch. Import or export profiles as JSON. Optional browser-account sync follows your profiles between devices and is on by default, including header values. No ads, analytics, account requirement or paid features.
