Context-aware form autofill — browser bundle

Standalone browser bundles for FillKit. Drop a single <script> tag into any page to get context-aware form autofill with realistic data — no build step required. Recognizes 100+ field types across 50+ languages.

Prefer a zero-code approach? Use the browser extension instead:

  Chrome Extension      Firefox Add-on

Usage

<script src="https://unpkg.com/@fillkit/browser/fillkit.iife.js"></script>
<script>
  const fk = await FillKit.FillKit.init({ mode: 'valid', ui: { enabled: true } });
  await fk.autofillAll();
</script>

Using a bundler?

Use @fillkit/core instead — it's tree-shakeable and doesn't bundle Faker.js.

npm install @fillkit/core

Intended Use

FillKit is designed exclusively for development, QA testing, and demo environments. All generated data is synthetic — realistic but entirely fake. FillKit is not intended for filling real forms with real personal information.
