Generate CUID2 identifiers locally in your browser without sending the current batch to another service. This tool is useful when you need compact public IDs for records, URLs, invitation links, fixtures, or client-side placeholders and want direct control over both batch size and output length.
What Makes CUID2 Different
CUID2 is built to reduce collisions across distributed systems while staying URL-friendly. Each value starts with a lowercase letter, uses only lowercase base36 characters, and mixes counters, host fingerprints, and random entropy before hashing the final result.
Choose Count And Length
Use shorter outputs when you want tighter slugs for demos, test data, or temporary links. Increase the length when you need more headroom for long-lived records or larger workloads, and raise the count when you want to mint a whole batch in one pass.
Copy Or Export The Final Batch
Review the generated list, then copy it or download it as a text file once the format looks right. Because everything runs locally, the identifiers stay in your browser until you decide to use or share them.
