…Frequently asked questions
Is the data realistic?
Names and addresses come from pools that look real. Emails use example.com so they cannot accidentally hit real inboxes.
Can I seed for reproducibility?
No — every generation is fresh random. For reproducible test data, use Faker.js in code with a seed.
Privacy concern?
All generation is in-browser; no data leaves your machine. The output is fictional, not derived from any real database.
