What does a URL parser do?

A URL parser breaks down a URL (Uniform Resource Locator) into its individual components: protocol (http/https), username, password, hostname, port, pathname, query string, and fragment (hash). This is useful for debugging API calls, understanding redirect URLs, or extracting specific parts of a URL programmatically.

What is the difference between hostname and origin?

Hostname is just the domain name (e.g., example.com), while origin includes the protocol and port as well (e.g., https://example.com:8080). Origin is the full combination that browsers use for same-origin policy enforcement. The URL parser displays both so you can use whichever part you need.

What are query parameters in a URL?

Query parameters are key-value pairs that appear after the ? in a URL, separated by & (e.g., ?name=John&age=30). They pass data to the server or client without changing the page path. The URL parser extracts each parameter into a table so you can see every key and its value clearly.

What is a URL fragment (hash)?

A URL fragment is the part after # (e.g., #section-2). It is processed entirely by the browser and is never sent to the server. It typically scrolls to an element with a matching id on the page, or in single-page apps, it is used for client-side routing.

Is my URL data kept private?

Yes. All parsing happens entirely in your browser using the built-in URL API. No data is sent to any server, so sensitive URLs containing tokens, passwords, or API keys remain completely private.
