What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify information in computer systems. It's commonly used as database keys, session IDs, and transaction IDs.
UUID v4 — Randomly generated. Best for most use cases where you just need a unique identifier with no ordering requirements.
UUID v7 — Time-ordered. Contains a timestamp prefix, making it sortable by creation time. Ideal for database primary keys where index performance matters.
All generation happens in your browser. No data is sent to any server. Your UUIDs are never stored or logged.
