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.
