RECIPES
Teach the tricky part.
A custom dropdown needs a click before a selection? Save those steps as a Recipe and let the next fill follow them.

EVERYDAY TESTING
Keep the details
under control.
01Repeat fill
Repeat the same test.
Restore the last fill on the same page, even after a reload. Keep the same values while you reproduce a bug.
For stable, supported fields during your browser session.
02Precise scope
Focus on one form.
Fill the whole page, choose a named form, or fill just the focused field. Keep the rest of the page out of your way.
Shortcuts: Ctrl+Shift+X fills the page, Ctrl+Shift+8 the focused form, Ctrl+Shift+9 the focused field (Command on Mac). Change them in your browser's extension shortcuts.
03Field rules
Keep the values you need.
Match fields by their label, name, ID, placeholder, or autocomplete attribute. Reuse fixed values or data generators.
Scope rules to a site and organize them by Profile.
04Regional data
Test beyond one locale.
Generate data in locales including English, Hindi, and French, or let the page and browser language guide it.
Review generated values against your own validation.
05Frames & Shadow DOM
Reach the nested fields.
Fill supported fields inside iframes and open shadow roots. Values go in through real input events, so framework-controlled state stays in sync.
Saved Actions fill child frames only when you opt in.
06Fill summaries
Know what happened.
See filled, skipped, and failed counts with reasons. Find the controls that need attention before you continue.
Inspect the completed form before submitting.
LOCAL BY DESIGN

Read the privacy detailsREADY WHEN YOU ARE
Your first fill.
Three small steps.
- 1
Install and pin.
Add FillMatic from your browser's extension store, then pin it in your extensions menu.
- 2
Open a form.
Start with our signup demo or a page you're testing. You're in control of when filling starts.
- 3
Fill. Inspect. Carry on.
Choose Fill all fields in the popup. Review the values and result summary before submitting.
Will it work with my forms?
It supports standard form fields, custom controls, rich-text editors, and many more. Compatibility depends on the control, so the demos are a good place to start. File inputs, closed Shadow DOM, and browser-owned pages are not supported.
Can I control the data and filling behavior?
Yes. Customize your test data with Field Rules, save repeatable workflows as Actions, and keep project setups separate with Profiles. Settings includes typing speed, ignored fields, and many more options.
What stays on my device?
Form inspection, data generation, and mapping run locally. Settings, Profiles, Actions, and Recipes are stored in your browser. Repeat-fill values last for the browser session.
Why does the extension need page access?
Page access lets it find fields and fill supported forms across frames when you ask it to. Use it on pages you own or are authorized to test. Saved Actions fill child frames only when you opt in; the Action builder scans and previews the main page.
