About the XML Diff

Compare two XML files side by side or inline, with changes highlighted. Press Normalize to pretty-print both so that formatting differences disappear and only real changes remain.

Built for developers

Why developers use it

• Private by design

  Runs 100% in your browser. Nothing you paste is uploaded, logged or stored on a server.

• Instant results

  Output updates as you type, with precise error locations when something is wrong.

• Works offline

  Once loaded, the tool keeps working without a connection. Install it as an app if you like.

• Free, no sign-up

  No accounts, no limits, no watermarks.
