Frequently asked questions
What is a UUID v4?
UUID v4 is a randomly generated 128-bit identifier, commonly used for database keys and API identifiers.
What is a ULID?
ULID is a sortable identifier that combines a timestamp with randomness, making it friendly for ordered IDs and URLs.
Are these identifiers unique?
They are generated from cryptographically secure random values, so collisions are extremely unlikely for practical use.
