Frequently asked questions
UUID version?
Common generators emit version 4 (random) UUIDs unless otherwise labeled in the UI.
Collision risk?
v4 collision probability is astronomically low for normal app volumes. Still enforce uniqueness constraints in databases.
Uppercase vs lowercase?
Canonical form is lowercase hex. Normalize if your system is case-sensitive.
ULID/NanoID?
This tool targets UUIDs. Use libraries in your stack if you need sortable ULIDs.
Offline?
Once the page is loaded, generation does not need a network round-trip.
