ModHeader Extension: HTTP Header Editor
Add a custom header, edit HTTP headers or remove them, on both requests and responses. A fast, clean, ad-free ModHeader alternative for Chrome that runs entirely in your browser.
What it does
ModHeader Extension lets you add, change or remove HTTP request and response headers on any website. Organize your rules into profiles, switch between them in a single click, and target exactly the sites you want with URL filters or regular expressions.
It's a fast, clean, ad-free ModHeader alternative, rebuilt to respect your privacy. Set a User-Agent, add an Authorization header, fix caching or debug CORS: the browser's own declarativeNetRequest engine applies your rules, so the extension never sees the content of your requests or the pages you visit.
Import your existing ModHeader backups, and export or share any profile as JSON. No account, no telemetry, everything stays on your device.
Key features
A clean ModHeader alternative
Looking for a ModHeader alternative for Chrome? ModHeader Extension does the same core job, modifying HTTP request and response headers, but keeps it free of ads, accounts and telemetry. Install it, import your ModHeader backup and your rules keep working.
Because it runs on Chrome's own declarativeNetRequest engine, this ModHeader Chrome extension never reads the content of your requests or the pages you browse. The free tier already covers what most people need; the one-time Pro upgrade unlocks redirects, a cookie editor, per-tab profiles and regex, with no subscription.
