A URL Parser and Query String Editor With Live Rebuild

Paste a URL, see it decomposed into protocol, host, port, path, query params, and hash. Edit any piece — or add/remove/update query params in a table — and the URL rebuilds live. Plus a percent-encoding panel for when you need to manually encode a value.

Working with URLs is surprisingly finicky. Query params with special characters need encoding. Repeated keys (like ?tag=a&tag=b) need array handling. Editing query params by string manipulation is error-prone. A structured editor removes the guesswork.
