UUID Generator
Create UUID v4 identifiers for fixtures, database keys, test data and application development without an account.
How this tool works
UUID v4 values use random bits with the version and variant fields set according to the UUID format. The browser crypto.randomUUID implementation supplies the values.
Example
Generate 20 UUIDs at once, copy the list and paste them into seed data or a spreadsheet.
Common questions
Are UUID v4 values guaranteed never to collide?
No finite random identifier is mathematically impossible to collide, but properly random UUID v4 collision probability is extraordinarily small for normal use.
Where are the UUIDs generated?
They are generated locally with the browser cryptographic API.
