Fillo — form backend for AI-built apps

Forms that live inside your product — no iframes, no hosted pages.

your-app.tsx

import { FilloForm } from "@usefillo/react";

export function Survey() {
  return (
    <FilloForm
      formId="customer-survey"
      onSubmitted={(id) => thank(id)}
    />
  );
}

A few lines render the form in your own UI. Fillo keeps the responses, files, and exports behind it.
