About this tool

What url parser does

Inspect the exact structure of a URL without opening it. The result separates credentials, hostname, port, pathname, query string, repeated parameters, and fragment.

How it works

The browser's standards-based URL parser normalizes the pasted absolute URL and exposes each component. The target is never requested, resolved, or checked for availability.

Common uses

When to use it

Debug callback, redirect, and deep-link URLs
Review query parameters copied from application logs
Separate a hostname, path, port, and fragment before editing

Scope

Limits to know

Parsing confirms URL syntax but does not confirm that a host or page exists
Pasted credentials are displayed locally; avoid using real production secrets

Quick answers

URL parser FAQ

Does the parser visit the URL?

No. It only analyzes the pasted string and performs no DNS, HTTP, or reputation lookup.

Can it parse repeated query parameters?

Yes. Repeated parameter names are preserved as arrays rather than silently overwritten.

What is the difference between host and hostname?

Hostname is the domain or IP portion. Host includes the port when a non-default port is present.
