GUIDE & CONTEXT

About this tool

ULIDs combine a timestamp with randomness in a 26-character identifier, making their standard form lexically sortable by time. NanoIDs use a configurable alphabet and length for compact random identifiers. Shorter or smaller alphabets increase collision probability; neither format is a substitute for database uniqueness checks.

How to use it

  1. Choose ULID for a timestamp-bearing identifier or NanoID for a compact random ID.
  2. For NanoID, set the length and optionally provide a custom alphabet.
  3. Choose the number of IDs and generate a batch.
Example

A ULID looks like 01ARZ3NDEKTSV4RRFFQ69G5FAV. A 12-character NanoID with alphabet abc123 uses only those six characters.
