FAQ
When should I use ULID instead of UUID?
ULIDs are sortable by creation time and still globally unique enough for many application workflows. UUIDs are the safer default when a system already expects UUID format.
Are generated values sent to a server?
The generator tools run in the browser in this frontend build. Avoid sharing generated secrets unless the receiving system is meant to store them.
