Does this fetch either URL?
No. It parses and compares the text in your browser without requesting the URLs.
Can it compare query parameters in a different order?
Yes. Query parameters are sorted by name for the comparison output.
Why do plus signs and %20 matter?
They can decode differently depending on form encoding rules, so the visible URL may not behave the same.
Is my data uploaded to a server?
No. The tool runs in your browser, so the text you paste stays on your device.
