URL parser & builder

Paste a URL and read its parts broken out: scheme, username, password, host, port with the scheme default noted, path segments, the query parameters as a decoded, editable table, and the fragment. Edit any part — or add, change and remove parameters — and the composed URL updates live with correct re-encoding; this tool covers structure, complementing the plain URL encoder. Internationalized hosts show both Unicode and ASCII (punycode) forms when they differ, with a plain-language note about look-alike IDN spoofing, and a relative URL resolves against the optional base.
