UUID Validator
A UUID (Universally Unique Identifier) is a 128-bit label used to identify information in computer systems. This free online tool validates UUID format, detects the UUID version (v1, v4, v7) and variant, and can also generate new random UUIDs. All processing happens locally in your browser with zero server uploads.
UUID Format Reference
v1 - Time-based with MAC address
v4 - Randomly generated (most common)
v7 - Unix timestamp-based (sortable)
