About this tool

v1, v4 & v5 Generation

Generate random (v4), time-based (v1), or deterministic name-based (v5) UUIDs. Bulk-generate up to 100 at once.

UUID Validation

Paste any UUID to instantly verify its format, detect the version, and view a labelled field breakdown.

Deterministic v5

Choose from well-known namespaces (DNS, URL, OID, X.500) or supply your own — the same inputs always produce the same UUID.
