Regex Tester & Validator

Matches URLs in unstructured text, supporting scheme-based URLs (http://, https://, mailto:), 'www.'-prefixed domains, and bare domain names with paths (e.g., example.com/page). It handles balanced nested parentheses within URLs, common in Wikipedia links, and is case-insensitive. Ideal for extracting or linkifying URLs from user-generated content, emails, or documents.
