UUID v7 Generator

Generate UUID version 7 identifiers — timestamp-prefixed and lexicographically sortable. Ideal for database primary keys.

Random, 128-bit, RFC 4122. Most widely used.

Common Use Cases

  1. Database primary keys with time orderingUse UUID v7 as a PostgreSQL or MySQL primary key to get the global uniqueness of a UUID with the index-friendliness of an auto-increment integer.
  2. Event log IDsAssign UUID v7 values to events so that logs are naturally ordered by creation time without a separate timestamp column.
  3. Distributed system trace IDsGenerate UUID v7 trace IDs across distributed services. The timestamp prefix lets you sort and correlate trace spans chronologically.
