About Fake Filler

What is Fake Filler?

Fake Filler is a browser extension (Chrome, Edge, Firefox) that fills all form fields on any page with realistic dummy data at the click of a button or keyboard shortcut. It eliminates the tedious, repetitive task of typing into test forms during development.

Who is it for?

It is built for web developers, QA engineers, and anyone who regularly tests or demonstrates applications with forms—React, Vue.js, Angular, or plain HTML. It is not for end-users filling real forms (e.g., checkout or registration).

Key capabilities

Users can customize field mappings with custom rules, set URL-specific profiles, and sync settings across browsers. Over 120,000 users rely on Fake Filler to save hours of manual form entry, making it a staple in development workflows.

Key features

  • One-click fill — Fill all inputs on a page instantly with a single click or keyboard shortcut.
  • Custom fields — Define your own dummy data for specific input IDs or names (free plan: 25 fields; Pro: unlimited).
  • URL-specific profiles — Create multiple profiles that auto-apply based on the website URL.
  • Sync across browsers — Your settings and profiles sync automatically across all browsers where Fake Filler is installed.
  • Zero ads or tracking — No ads, no analytics, no data collection.
  • Works on any framework — Compatible with any website, including React, Vue.js, and Angular.
