FillMatic
Form Filler Extension for Realistic Test Data
FillMatic is a browser extension that fills web forms with realistic, locale-aware fake data, reusable Actions, Profiles, and Recipes for developers and testers.
I'm Abdul Samad, and I built FillMatic. I build web apps, and a big part of testing them means filling the same signup, checkout, and onboarding forms over and over. Basic form fillers helped, until they hit a React-controlled input, a custom date picker, or a rich-text editor. Then I was back to typing johndoe36@example.com by hand.
FillMatic fills web forms with realistic, locale-aware test data in one click (or Ctrl/Cmd+Shift+X), and it's built for the parts of modern apps that usually break.
Fires the events a person's typing does (focus, input, change, blur), so your framework and validation pick up each value.
Drives custom dropdowns, date pickers, switches, and sliders through their accessibility roles, the way a user would.
Multi-step flows: click a button, open a dropdown, pick an option, then fill the form inside the modal. Record it once, replay it in one click.
Works for the flows you repeat:
Actions: a one-click button per site or per page with the exact values you want
Built-in Actions for Stripe test checkout: successful, declined, and 3D Secure test cards in one click
Profiles and per-site or per-page field rules
Recipes: record a few clicks once to teach it a custom widget it doesn't know
All your settings and test data stay in your browser.
I'd love your feedback. Which form or widget breaks your current filler? Send me the trickiest one, and I'll try it today.
