UUID Generator
Make one or hundreds of unique IDs for databases, test data, files and code. Pick random version 4 or time-ordered version 7, choose the format, then copy. You can also paste a UUID to check it.

Follows RFC 9562. Version 4 UUIDs use 122 random bits from your browser's Web Crypto (crypto.getRandomValues), so a clash is astronomically unlikely. Version 7 UUIDs start with the current time in milliseconds, so they sort in the order they were made, which suits database keys, but anyone can read that time back from the ID. UUIDs are identifiers, not secrets: don't use them as passwords or security tokens.
