frequently asked questions
what is the difference between v4 and v7?
v4 is fully random. v7 starts with a millisecond timestamp so ids sort by creation time, which is better for database indexes.
are the ids secure?
they use crypto.getRandomValues in your browser, a cryptographically secure source.
how many can i generate?
up to 1000 at once, nothing is stored or sent anywhere.
