Why this one is useful
Batch generation is faster than copying one UUID at a time when you are filling fixtures, test payloads, or admin seed data.
Prefixes, suffixes, and separator control let you adapt the output to code, CSV-like data, or quick manual pastes.
Output templates and presets make it much faster to jump into JSON fixtures, SQL inserts, or compact identifier lists.
It runs fully in the browser, so there is no request, no login, and no waiting around for a basic task.
Common uses
Generating record IDs for mock API responses.
Preparing test users, orders, and seeded database rows.
Creating compact identifiers for logs and quick prototypes.
Making one-off identifier lists for QA and admin tools.
