FauxFill – Test Data Form Filler

Fill any web form with realistic fake test data in one click — 8 languages (EN/ES/DE/FR/IT/PT/NL/JA). For developers & QA.

Stop typing "test@test.com" a hundred times a day. FauxFill fills any web form with realistic, clearly-fake test data in a single click — names, emails, phone numbers, addresses, dropdowns, dates, card numbers, and more. Built for developers and QA testers who fill the same forms over and over. Whether you call it test data, dummy data, mock data, fake data or sample data, FauxFill generates it and drops it into every field for you. WHY FAUXFILL • One click (or Alt+Shift+F) fills every visible field on the page. • Smart detection — reads each field's type, name, label, placeholder and autocomplete to pick the right kind of data. • Works on modern apps — sets values the way React, Vue and Angular actually detect, so fields don't silently clear on submit (where older fillers fail). • Realistic but obviously fake — @example.com emails and standard public test card numbers. Never real, never anyone's private data. • Multilingual — fills in English, Spanish, German or French, and even recognizes localized field labels (Vorname, Nombre, Prénom). Auto-detects your browser language, or pick one in the popup. • Private by design — everything runs locally. FauxFill collects nothing and sends nothing anywhere. HOW TO USE 1. Open any page with a form. 2. Click the FauxFill icon → "Fill this page" (or press Alt+Shift+F). 3. Done. Toggle "overwrite" if you want it to replace values that are already there.
