UUID inspector

Decode a UUID — version, variant, and for v1/v6/v7 the embedded timestamp and node.

Parsed in this browser — the UUID is not sent anywhere.

Hyphens, braces, and a urn:uuid: prefix are accepted. Timestamps decode for v1, v6, and v7 (RFC 9562).

How to use

  1. Paste a UUID.
  2. Read the version and variant.
  3. Check the embedded timestamp for v1/v6/v7.

What it supports

Validates the 8-4-4-4-12 shape and decodes RFC 4122 fields. v1/v6 timestamps are Gregorian 100-ns ticks; v7 is Unix ms. Nil/max and non-RFC variants are flagged honestly.
