FillKit
FillKit is a form-filling tool for development, QA testing, and demos. It fills fields with realistic, context-aware data in one click, with the aim of reducing manual typing into web forms.
The product automatically detects what each field expects and can populate names, emails, phones, dates, and credit cards. It also supports 50+ locales, with locale-appropriate names, addresses, phone numbers, and date formats. Other documented controls include switching between valid data, invalid data, boundary values, and special characters, as well as pinning specific values. FillKit is also described as helping teams catch broken validation rules, missing error messages, and formatting issues.
FillKit works on any website and is delivered as browser extensions for Chrome, Edge, and Firefox. The Chrome and Firefox extension installation flow is described as requiring no account or sign-up, and the product also has an npm package for developers. Its SDK and extensions are open source, and the generated data stays local; no real user data is collected. The page also says a managed API and team features are coming soon.
Pricing shown on the site includes free browser extensions for Chrome, Edge, and Firefox. The page identifies ClavisCore LLC in the footer.
