Fake data Chrome extension for form testing
If you search for a fake data Chrome extension, you usually want one outcome: fill a stubborn web form with believable dummy values so you can keep shipping.
Mock Data Form Filler is that form filler. It writes local mock data into names, emails, phones, addresses, selects, and more—then gets out of the way.
Local fake test data, not another cloud account
Many tools mix personal autofill, password vaults, and remote generators. This extension stays on one job: mock data for testing. Values are generated on your device. There is no fill API and no signup wall.
How developers and QA use it
- Registration and onboarding forms on localhost
- Checkout and address blocks on staging
- Admin panels with long required field lists
- Quick passes before a PR demo
Click the toolbar icon, press Alt+Shift+F, or right-click a field. Password fields stay empty by default.
