Fill — Instant Form Filler

One click fills every form field with realistic local test data. Smart field matching, private, seedable, optional saved profiles.

Fill populates every field on a form with one click — realistic, locally-generated test data that actually matches each field. Built for developers, QA and anyone who fills out forms all day. Stop typing fake data by hand. Click the Fill icon, hit "Fill this page", and names, emails, phone numbers, addresses, dates, dropdowns, checkboxes and radios all get sensible values instantly. ⚡ ONE-CLICK, SMART FILL • Fills text, email, tel, url, number, date, color, textarea, select, checkbox and radio controls. • Matches each field by its label, name, type and placeholder — the email field gets an email, the phone field gets a phone. • Names and emails stay consistent within a fill, so the data looks real. 🎯 REPEATABLE & CONTROLLABLE • Set a seed to get the exact same data every time — perfect for reproducible tests. • Undo the last fill or clear the whole page in one click. • Number and date fields respect their min/max limits. 👤 SAVED PROFILES • Fill from random test data, or save your own profiles (e.g. a test account) — all stored locally. 🔒 100% LOCAL & PRIVATE • All data is generated on your device. No account, no network requests, no data collection. • Uses only activeTab + scripting + storage — it acts on a page only after you click. Free, no ads, no tracking.
