FAQ
What UUID version does this tool generate?
This first release generates UUID version 4 values.
Are the UUIDs random?
They use the browser crypto API, which is appropriate for general identifier generation in development workflows.
Can I generate ordered or time-based UUIDs here?
Not in the first version. The current scope is limited to UUID v4 to keep the interface narrow and predictable.
