Why Choose Form Filler?
Built for speed, accuracy, and privacy. The only form filler you'll ever need.
Smart Context Detection
Most fillers just look at `name='email'`. We look at the label, the placeholder, and the surrounding text. Our weighted scoring algorithm ensures the right data goes into the right field, every time.
Native Safari Support
Mac users, we heard you. Form Filler is built as a native Safari App Extension, ensuring smooth performance and full compatibility with the Apple ecosystem.
Localized Data
Testing a Vietnamese e-commerce site? Or a Japanese registration form? We generate culturally accurate names, addresses, and phone numbers for multiple locales.
Total Privacy
Your data is yours. Form Filler is open-source and operates entirely offline. No analytics, no tracking, no data sent to the cloud.
How It Works
Install
Add the extension to your browser in seconds. Available on all major stores.
Configure
Set up custom fields, regex patterns, or hotkeys if you need specific data.
Click
Hit the icon or use the hotkey (Cmd+Shift+F) and watch your form fill instantly.
