About
FillKit fills web forms with realistic test data in one click. It reads page structure, labels, and field attributes
to detect what each input expects — then generates appropriate values automatically.
A checkout form gets a valid card number with matching expiry and billing address. A signup form gets a real-looking
name, email, and strong password. It recognizes 150+ field types across 50+ locales.
Key features:
- Valid and invalid modes — generate correct data or intentionally broken values for edge-case testing
- Keyboard shortcuts for instant filling (Ctrl+Shift+K fills all forms)
- Customizable — override specific fields, set default email domains, choose your locale
- Draggable widget or inline per-field filling mode
- Works entirely offline — no data leaves your browser
Built for developers, QA engineers, and demo environments. All generated data is synthetic. Open source under the MIT
