What it does
Parse any URL's query string into key/value pairs — including repeated keys, array-style key[] keys, and bracket-notation key[a][b]. Shows raw and decoded values so you can catch double-encoding bugs.
For the full URL breakdown use URL parser. For UTM parameters specifically, UTM parser. To encode single values, URL encoder/decoder.
