URL Rewriter is a free Chrome extension developed by John Ahlgren. It falls under the category of Browsers and is specifically classified as an Add-ons & Tools subcategory. This handy tool allows users to rewrite URLs using custom rules.

With URL Rewriter, users can easily rewrite omnibox strings into desired URLs. The extension provides a simple and straightforward interface to configure the rewrite rules according to your preferences. The rules are defined using regular expressions with capturing groups, and the rewritten URLs can include placeholders for the captured groups.

For example, you can set up rules to grab the first URL in a string and use it as the rewritten URL. Or you can identify URLs with the "www" prefix and rewrite them accordingly. The extension also supports handling URLs with variations like "www2", "www3", and so on.

In case no specific rule matches, URL Rewriter offers a fallback option. It allows you to perform a Google search using the entire string as the search query.

URL Rewriter is a valuable tool for users who need to customize and rewrite URLs based on their requirements. It provides flexibility and control over URL rewriting, making it easier to navigate the web efficiently.
