What can Gooreplacer do?

Redirect URLs

Redirect requests to alternative CDNs or custom endpoints. Supports static URLs, regex substitution, and URL transforms.

Block Requests

Block unwanted resources — ads, trackers, or any URL pattern you specify. Uses wildcard and regex matching.

Modify Headers

Set, append, or remove HTTP request and response headers. Useful for debugging, testing, and bypassing restrictions.
