Auto Fill Fake Data — Test Form Filler

Fill forms with realistic test data in one click. Localized names, phones, addresses. Supports dates, selects, checkboxes and more.

Fill any form with realistic, locale-aware test data in one click — the fastest way to stop typing "test test test" while building or QA-testing forms. Auto Fill Fake Data reads each field's type, name, placeholder, label and autocomplete attribute, then generates data that actually matches what the field expects: names, emails, phone numbers, addresses, dates, and more — in the same language as the page you're on. WHAT IT DOES ✓ One click, one hotkey (Alt+Shift+F), or right-click "Fill this form" / "Fill all forms" ✓ Detects the page's language automatically and generates native names, cities and addresses — Cyrillic on Russian sites, umlauts on German ones, no more "John Doe" on a Russian checkout form ✓ Full field-type coverage: text, email, tel, url, password, number, date/datetime/month/week/time, select, checkbox, radio, color, range — respecting min/max, step and required constraints ✓ Works inside React, Vue, Angular and other framework-controlled forms, not just plain HTML ✓ 9 locales out of the box: English, Russian, German, Spanish, French, Portuguese (BR), Polish, Turkish, Ukrainian PRO FEATURES ✓ Edge-case profile — maximum-length strings, unicode names, boundary dates, for stress-testing validation ✓ Invalid profile — malformed emails, XSS/SQL-like strings, out-of-range values, for testing how your form handles bad input ✓ Custom per-domain rules — force a fixed value or a specific generator for any field, matched by regex ✓ Presets — save and switch between rule/profile bundles for different projects in one click ✓ Export/import settings as JSON to share with your team 100% PRIVATE Every value is generated locally, inside your browser. Nothing you type, and nothing this extension fills, is ever sent to us or to any third party. No account required to use the free tier. Free forever for the Valid data profile, full locale support, and all field types. Upgrade to Pro for edge-case/invalid testing, custom rules, presets and team-friendly export/import.
