Features
- Human-readable — IDs show their type, no cross-referencing needed
- Type-safe — Compile-time checking in supported languages
- Unambiguous — One canonical string per ID (unlike UUID hex)
- Sortable — Strings sort correctly as-is
- URL-safe — No percent-encoding needed
- Time-ordered option — V0 sorts chronologically (like UUIDv7)
- Random option — V1 for full randomness (like UUIDv4)
- UUID-compatible — Works with existing tooling and infrastructure
- Same size — 128 bits, no storage overhead
- Encryption extension — Hide timestamps by converting V0 to V1
