How to use URL Parser / Inspector

Paste any complete URL (such as https://example.com:8080/products/shoes?utm_source=google&sort=asc#reviews).

Inspect the parsed breakdown of protocol, host, pathname, query string, and hash fragment.

Use the separated components to debug analytics tags, canonical rules, or API endpoints.

Complex tracking links, OAuth callback URLs, and faceted e-commerce URLs often pack dozens of query parameters and encoded tokens into a single string. Paste any URL into this free URL parser and inspector to break it cleanly into its WHATWG URL components.
