FAQ
How does the parser handle complex query strings with multiple values for one key?
It identifies repeated keys (e.g. ?tag=web&tag=css) and displays them as distinct indexed parameter entries.
Can it parse URLs containing authentication credentials?
Yes, usernames and passwords in the authority component (e.g. https://user:pass@example.com) are parsed into discrete fields.
What is the difference between origin, host, and hostname?
'hostname' is the domain (e.g. api.example.com), 'host' includes the port (api.example.com:8080), and 'origin' includes protocol (https://api.example.com:8080).
Is my URL data sent to a backend server?
No, parsing is conducted entirely within your local browser session.
