Smart Autofill – QA Test Data

Fill web forms with realistic, connected test data in one click. Runs locally; no API key required.

Testing a form usually means typing the same details again and again. Smart Autofill fills the whole page in one click, so you can get straight to testing. Built for developers and QA engineers. Use it on forms you own or have permission to test. REALISTIC, CONNECTED DATA Every fill creates one consistent test person. The email matches the name, and the city, state, postal code and phone number all belong to the same country. • Names, emails, phone numbers, addresses, companies, job titles and dates • Data for India, the United States, the United Kingdom, Canada and Australia • Tax ID and postal code formats for each country • Follows format hints shown on the page, such as "Format: XX-XXXXXXX" • Reads the page's own country selection and generates matching data TEST MORE THAN THE HAPPY PATH Switch the whole form to a different kind of test data in one step: • Invalid data: wrong formats, and values just past each field's declared limits • Minimum and maximum limits: exactly at each field's declared limits • Edge cases: awkward but valid names, Unicode, emoji and special characters • A label on the toolbar icon shows which mode is on, so you never test with bad data by accident • See which fields failed the browser's validation, without submitting RIGHT-CLICK ANY FIELD Fill a single field, or pick from a library of problem values: text lengths, number limits, valid and invalid emails, unusual names, Unicode, whitespace, special characters and dates. INDIAN TEST IDENTIFIERS Generates correctly formatted sample values for Aadhaar, PAN, GSTIN, IFSC, UPI ID, bank account, passport, voter ID and driving licence fields. These are randomly generated test values for validating form behaviour. They are not real documents and must not be used as real identity details. WORKS WITH MODERN FORMS • Plain HTML, React, Vue and Angular forms • Dropdowns that depend on each other, such as Country, State and City • Common component libraries and date pickers • Same-origin iframes and shadow DOM YOU STAY IN CONTROL • One click on the toolbar icon, or from the right-click menu of any field • Keyboard shortcuts to fill the form, fill one field, clear the form and switch test data • Undo the last fill or clear the form from the icon's right-click menu • Fill required fields only, to check how optional fields behave • Custom rules, such as a fixed value for any field containing "customer" • Saved test profiles for different environments or user types • Choose how dropdowns, radio buttons and checkboxes are filled SAFE BY DESIGN • Never submits a form or clicks a submit button • Skips hidden, disabled and read-only fields • Leaves payment card, one-time code and CAPTCHA fields alone by default • Only runs when you ask it to PRIVATE BY DESIGN Everything happens in your browser. No account, no API key, no analytics and no network requests. Your settings stay on your device. Some sites use forms that can't be reached, such as cross-origin iframes, and Chrome doesn't allow extensions on its own pages.
