URL Parser & Diff

Break a URL into parts, edit query params, rebuild it — or paste two URLs and see exactly what changed.

Why parse and compare URLs?

Tracking links, API endpoints and UTM campaigns often differ by a single query param. A local URL parser and diff makes those differences obvious without sending links to a third party.

How it works

Paste a URL and click Parse to split protocol, host, path, query and hash. Edit parts or query rows and Rebuild. Switch to Compare, paste two URLs, and see field-by-field and param-by-param differences.

Is my data safe?

Yes. Parsing and comparison run entirely in your browser with the URL API. Nothing is uploaded to DevsDrill servers.
