Regex Tester & Validator

Extracts query string parameters from URL GET API requests by matching key-value pairs starting with ? or &. Captures three named groups: key (word characters before =), value (word chars, plus, comma, period, or hyphen), and an optional option group following a colon separator. With the global flag, it matches all parameters in a URL, making it ideal for parsing API query strings, logging requests, or processing web analytics data.
