One script tag. No framework. No build step. Works on plain HTML pages.
For static sites, classic server-rendered apps, WordPress themes, or anywhere a build step would be overkill. Drop two script tags into your HTML and the widget appears.
<!doctype html>
<html lang='en'>
<body>
<!-- your page -->
<script src='https://unpkg.com/@usero/sdk'></script>
<script>
Usero.initUseroFeedbackWidget({
clientId: 'YOUR_CLIENT_ID',
})
</script>
</body>
</html>Replace YOUR_CLIENT_ID with the id from your Usero dashboard.
Built for Vanilla JS
Paste two script tags. No npm, no bundler, no toolchain. Works in any HTML page on any host.
unpkg and jsDelivr both serve the IIFE bundle automatically. Pin a version and it never changes underneath you.
The vanilla build never imports React. Plain HTML pages pay zero framework overhead.
WordPress, Ghost, Webflow, Squarespace, any platform that lets you paste raw HTML. The widget installs the same way.
Canny still requires an account dance and a 200kb iframe. Usero is a 12kb script with no iframe and no auth bridge.
