How it works

Instantly connect your HTML form and start collecting data.

<form action="" method="POST">
    <input name="fieldname">
    <button type="submit">Submit</button>

Point to our backend

Add the form endpoint URL we provide to your form action. That's literally all you need to start collecting submissions.

<form class="kf-form" action="" method="POST">
    <input name="fieldname" rules="required|max:30">
    <button type="submit">Submit</button>

<script src="" defer></script>

Supercharge your form

Use our frontend script to instantly supercharge your form, with frontend/backend validation logic, special field types, and much more. Simply add the kf-form class on your <form> tag, and add our special script before your closing </body> tag.
