Generate UUID v4 or v7 identifiers, one at a time or in bulk.
Generate cryptographically random UUID v4 identifiers, or time-ordered UUID v7 identifiers (better for database index locality), one at a time or in batches of up to 1000.
All UUIDs are generated locally using your browser's secure random number generator — nothing is requested from a server, so there's no rate limit and no network delay.
v4 is fully random. v7 embeds a timestamp in its most significant bits, so v7 values sort roughly chronologically — useful as database primary keys to avoid index fragmentation.
