See What's Hiding in Your URLs

Paste a URL and every query parameter appears decoded — name, value, and the raw original side by side. Nothing leaves your browser.

URL Parameter Inspector

Built for developers and indie makers who debug URLs and API callbacks daily. Fully client-side — no network calls, no storage.

How to use:

  1. Paste or type any URL in the box above — parameters appear instantly as you type
  2. Each row shows the decoded name and value next to the original raw (encoded) form; + is decoded as a space
  3. Edit a name or value and the rebuilt URL updates live — copy it when you're done
  4. Use "Copy all as JSON" to grab every parameter as a JSON object (repeated keys become arrays)
  5. Rows flagged with ⚠ sensitive contain names like token, key, secret or password — be careful before sharing them

Everything runs in your browser: no network calls, no analytics on your input, nothing stored.
