Paste a URL and this analyser splits it into its component parts: protocol, subdomain, host, port, path, each query parameter as a separate key-value row, and the fragment after the hash. Query parameters are percent-decoded, which is what makes a long tracking URL comprehensible — a link with utm_source, utm_medium, gclid and a nested redirect target is almost unreadable as one string but obvious as a table. The fragment is shown too, with the reminder that everything after # never reaches the server; it exists only in the browser, which explains why fragment-based parameters are invisible in server logs and most analytics.
Free, fast, and runs entirely in your browser — no signup, no upload to a server.
