One form. Everything behind it stays connected.

Own the route, UI, and product context. Stop rebuilding rules, uploads, response tooling, and delivery every time the product needs another form.

SupportForm.tsx
import { Fillo } from "@usefillo/react";

export function SupportForm() {
  return (
    <Fillo.Form id="support">
      <Fillo.Email id="email"
        label="Work email" />
      <Fillo.Phone id="phone"
        label="Phone" />
      <Fillo.Rating id="urgency"
        label="How urgent?" />
    </Fillo.Form>
  );
}

no <iframe>

Your interface stays yours.

Your route and components render the form directly—no iframe, foreign font, or detached flow. Start with the default controls, replace individual fields, or own the entire layout.

React, Vue, Svelte, Astro, or plain browser apps. Your CSS and design system stay in charge.

Every answer carries context.

Attach the account, user, plan, page, or product state without turning each one into another question.

Attached to the response, invisible to the user.

Files can go straight to storage you own.

Browser-direct to connected S3, Drive, Box, or R2—multiple large files included. Fillo keeps each durable file reference attached to its response.

A response becomes useful work.

Review answers, files, context, and delivery state together—then export them or send them into the systems that act next.

Change it without breaking old answers.

Keep the published form collecting while you edit. New versions can change fields; old responses keep their original schema context.

Build it from your coding agent.

Paste one prompt. Your agent asks what the form should collect, builds it into your app, and gives you the working preview.

Add a Fillo form directly to this app. Ask me what it should collect, match the existing UI and route context, and follow https://fillo.so/agents.
Prompt it. Preview it in your app. Publish when it looks right.

“Tried the agent setup. Literally one prompt and it was live on all help pages on rotato.app”

Frequently asked questions

When should we use Fillo?

Use Fillo when the form belongs inside your product: onboarding, support, feedback, intake, file requests, and approvals that need your route, components, account context, or ongoing maintenance.

Can my coding agent set Fillo up end to end?

Mostly. Your agent installs the Build-with-Fillo skill, provisions the form, adds it directly to your app, and gives you a live preview. You claim the workspace to keep it, and connect external accounts yourself when an OAuth or account-level decision is required.

Can I use my own design system?

Yes. Fillo renders accessible HTML controls directly inside your app, not an iframe. Start with the default renderer and restyle it, replace fields with your own components, or use the headless hooks.

Where do uploaded files go?

For durable storage, connect Google Drive, Box, Amazon S3, or Cloudflare R2. File bytes upload browser-direct while Fillo keeps the response and durable file reference together. Temporary Fillo transit storage is capped and short-lived; the current limits are published on the pricing page.

What does Fillo cost?

Free includes 200 completed responses a month with no time limit. Everything is free for 30 days, then €35 ($39) a month for 5,000 responses. Extra responses are €0.007 ($0.008) each. Every render method is included on both plans.

The next form does not need another backend project.
