About Header Override

Header Override is an open-source browser extension for Chrome, Firefox, and Edge that lets developers modify HTTP request and response headers, cookies, and local profiles. It allows you to scope matching rules with URL filter patterns and keep local rule profiles for different projects. All rules are stored securely in your browser without tracking or external servers.
