Why bulk IDs matter

UUIDs and ULIDs are everywhere — from database keys to API mocks. This tool keeps generation local, sortable, and shareable so you can paste batches into fixtures or docs without relying on external APIs.

Common workflows

Generate NDJSON for seed scripts.
Decode ULID timestamps to verify ordering in distributed systems.
Share deep links to reproducible batches when collaborating with teammates or LLMs.
