About MockFill — Fill forms with realistic fake data

MockFill fills any web form with realistic, coherent fake data in a single click — names, emails, addresses, phone numbers and more — so you can test forms and demos instantly. Why MockFill: • Realistic & coherent data (a matching first name, last name and email), not random gibberish. • One click — no setup. • 100% local: nothing is ever sent to a server, no account, no tracking. • Minimal permissions (activeTab): it only acts on the page you click on. Free forever for everyday use. Pro (coming soon) adds more locales and custom presets
