Form Filler

Fills HTML form fields with realistic fake US data.

Form Filler is the ultimate developer and QA tool designed to streamline form testing. Instantly fill complex forms, multi-page flows, and custom select dropdowns with high-quality, geographically consistent fake US data. Whether you are testing a checkout flow, a user registration system, or sandbox credit card payments, Form Filler saves you hours of manual typing and copy-pasting. Key Features One-Click Form Filling: Right-click anywhere on the page and select "Fill entire form with fake data" to populate all inputs, select boxes, and textareas in under a second. Geographically Consistent Profiles: Generates matching address details (State, City, and corresponding ZIP code) and logical email/username patterns to pass form validations. Built for Custom UI Component Libraries: Automatically detects and interacts with custom select dropdown menus (such as Radix UI, Shadcn, Ant Design, and React Select). Supports Payments & Iframes: Injects seamlessly into subframes and iframes to automatically fill sandbox test card credentials (like Stripe or Braintree credit card fields). Precision Proximity Label Mapping: Intelligently identifies labels positioned visually next to inputs to guarantee that "First Name" gets a first name and "Full Name" gets a full name. Custom Context Menu: Right-click on any single field to choose from a clean, visually grouped list of data types (Names, Contact Info, Address, Web details, Financial numbers, and Placeholder Text). Respects Form State: Automatically skips disabled, read-only, hidden configuration inputs, and Captcha fields to keep your form flows functioning. Privacy-First & Secure: Runs 100% locally in your browser. Form Filler does not track, collect, or transmit any data outside your machine.
