What this tool is good for
ULID stands for Universally Unique Lexicographically Sortable Identifier. It combines a timestamp prefix with randomness so generated IDs can be sorted in roughly chronological order.
That makes ULID useful in some business workflows as a UUID alternative, especially when readable sorting or time ordering matters.
How to use it
- Choose how many ULIDs you want to generate.
- Enable JSON array output if you want to paste the result directly into test fixtures or code.
- Refresh to generate a new batch, then copy the result.
Format notes
A ULID is a 26-character string. It includes 10 timestamp characters and 16 random characters, so it stays sortable while still being unique enough for normal application workloads.
