UUID Generator

Create UUIDs locally in the browser for databases, tests, APIs, logic identifiers and technical documentation. Generation runs client-side and does not send values to the server.

10 UUIDs

UUIDs are technical identifiers. For passwords, secrets or API keys, the random token generator is usually the better tool.

Notes

UUID v4 uses random bytes and works well for general identifiers.
UUID v7 includes a time component and can be useful for sortable database IDs.
Nil UUID consists only of zeros and is a placeholder, not a random ID.
Max UUID consists only of F and can be useful for tests.
Values are generated locally in the browser. Nothing is sent to a server.
