How to use ULID Generator

Click generate, and the tool builds a ULID — a 26-character, timestamp-prefixed identifier in Crockford Base32 that sorts lexicographically by creation time.

Frequently asked questions

Why would I pick ULID over UUID?

ULIDs sort correctly by creation time when ordered as strings, which UUIDs don't — useful for database indexes where insertion order matters.

Is this tool free to use?

Yes. This tool is completely free to use with no daily limits and no signup required.

Can I generate more than one at a time?

Most ID generators here support a bulk mode — set the count and copy the whole list at once.
