UUID v4 Generator.

Generate UUID version 4 identifiers in the browser

Choose how many identifiers to create, from 1 to 25, then generate a list of UUID v4 strings. Copy or download them for development and test fixtures.

Example and important limitation

For example, prepare identifiers for locally seeded demo records. UUIDs are identifiers, not authentication tokens; do not use them alone to authorize access to sensitive data.
