The big win: ULIDs sort by creation time as plain strings — which makes them perfect as database row IDs, log keys, or anywhere you want ordering for free. The 26-character Crockford-base-32 encoding is URL-safe and case-insensitive. Generate one or many at once (up to 100), or override the timestamp to produce a ULID for any past or future moment.
