V4 Random
122 random bits. Most common for session IDs, API keys. Use crypto.randomUUID()V7 Sortable ✨
48-bit Unix timestamp + 74 random bits. Optimal for DB primary keys. RFC 9562 (2024)V5 Deterministic
SHA-1 hash of namespace + name. Same input = same UUID. Ideal for content addressing🆚 v4 vs v7?
New projects: use v7 — it's sortable & DB-friendly. Legacy systems: v4 is fineSponsored
