Generate cryptographically random version 4 UUIDs for test data, records and development workflows.
THREE SIMPLE STEPS
UUID version and variant bits are set correctly and random bits come from the browser cryptographic random source. Collision risk is very small but not a mathematical guarantee of uniqueness. These identifiers are not a replacement for authorisation or access-control checks.
Yes. Generate between 1 and 1,000 UUIDs per batch.
No. This tool produces random UUID v4 values, not time-ordered UUIDs.
