About this tool
The UUID generator creates random version 4 identifiers using the browser cryptographic random source. Version 4 UUIDs are random, so the chance of two ever colliding is vanishingly small for normal use. They are generated independently in your browser, which makes them ideal for keys and test data but means they are not coordinated across machines.
