FillMatic

Fill test forms with realistic dummy data in one click. Stop typing johndoe36@example.com for the 36th time just to get through the same signup flow. FillMatic helps developers and QA testers move through signup, checkout, onboarding, settings, and internal-tool forms without repeatedly typing the same details. It fills names, emails, phone numbers, addresses, companies, usernames, passwords, dates, notes, and more. It goes beyond basic text inputs. It works with modern web apps, framework-controlled fields, custom widgets, rich-text editors, open Shadow DOM roots, and forms inside iframes. KEY FEATURES - One-click autofill Fill an entire form with realistic, locale-aware test data from the extension popup or a keyboard shortcut. - Built for modern frontend stacks Test React, Vue, Angular, and other modern applications. FillMatic supports controlled inputs, late-mounted fields, selects, checkboxes, radio groups, date fields, ARIA comboboxes, listboxes, sliders, switches, spinbuttons, and rich-text editors. - Framework-friendly browser events FillMatic dispatches focus, input, change, and blur events so frameworks and validation logic can recognize filled values correctly. - Reusable Actions Create page-specific fill buttons for workflows you run often. Match pages by hostname or URL, map fields by labels and common HTML attributes, set exact test values, and optionally scope an Action to part of a page. - Profiles and field rules Keep different test identities and settings for different scenarios. Add site-specific field rules when a form needs predictable values every time. - Recipes for custom widgets Teach FillMatic how to handle complex controls with reusable steps such as click, type, select an option, wait for an element, or press a key. Recipes run before built-in widget handling so your instructions take priority. - Built-in Stripe Checkout Actions Speed through test-mode Stripe checkout forms with test payment data and reusable Actions for successful or declined flows. LOCAL-FIRST PRIVACY FillMatic does not require an account and does not operate an application backend. Your settings, Profiles, Actions, Recipes, and saved test values stay in your browser. Page contents used for field mapping are not sent to a FillMatic server. Use FillMatic only on pages and accounts you own or are authorized to test. Spend less time typing test data and more time building, debugging, and shipping reliable forms.
