If the form is already built and only needs somewhere to send submissions, an endpoint may be everything the team needs. Point the HTML at an endpoint or use its React hook, then keep owning the fields, state, and layout in your app.

Fillo is useful when the form still needs to be built. It renders the fields inside your app and also handles server checks, uploads, responses, and exports.

Which should you choose?

When Fillo fits

You want the fields rendered from one schema as native React or DOM controls.
The same field IDs and rules should drive the UI, server validation, responses, and exports.
A teammate needs a response grid and safe editor-managed changes after launch.
Uploaded files should go browser-direct to Google Drive, Box, or S3-compatible storage such as Amazon S3 or Cloudflare R2 that you connect.

When to stay on Formspree

The form markup is finished and a submission endpoint is the missing piece.
You want to keep form state, layout, components, and client behavior entirely in your code.
A contact, lead, or other straightforward form does not need a schema-driven renderer or product response workspace.
Formspree's email, routing, and workflow setup already matches how the team handles submissions.

Formspree covers the submission step; Fillo covers building, validating, and managing the form around it.

What changes in a React app

Formspree's React library gives your component a useForm() submission handler. You still write the inputs:

tsx

import { useForm } from "@formspree/react";

export function ContactForm() {
  const [state, handleSubmit] = useForm("your-form-id");

  return (
    <form onSubmit={handleSubmit}>
      <label htmlFor="email">Work email</label>
      <input id="email" name="email" type="email" required />
      <button disabled={state.submitting}>Send</button>
    </form>
  );
}

Fillo can render the fields from JSX or a published schema:

tsx

import { Fillo, createClient } from "@usefillo/react";
import "@usefillo/react/styles.css";

const fillo = createClient({ key: import.meta.env.VITE_FILLO_KEY });

export function ContactForm() {
  return (
    <Fillo.Form client={fillo} id="contact" title="Contact us">
      <Fillo.Email id="email" label="Work email" required />
    </Fillo.Form>
  );
}

You can use Fillo's default styling, change it, or replace individual fields with your own components. The same field names and rules are then used in the form and on Fillo's server.

Key differences

Decision	Fillo	Formspree
Starting point	A schema rendered by Fillo	HTML or JSX you write, optionally starting from a template
React integration	Native renderer, field components, and headless hooks	`useForm()` and related helpers for submitting your component
Validation	One schema used by the client and Fillo's server	HTML/client validation plus Formspree dashboard or configuration rules
File uploads	Browser-direct to connected customer storage, with the reference kept on the response	Multipart uploads stored with Formspree submissions on eligible plans
Working with responses	Response grid, detail, context, versions, exports, and delivery state	Submissions dashboard, email notifications, routing, workflows, and integrations
Changing fields	Edit an editor-managed form in Fillo or publish a code-managed schema	Change the HTML or JSX in your application

Formspree Workflows can add server-side validation, integrations, automatic field mapping, and delivery retries. The difference is that Fillo also renders the fields and uses the same rules for the form, server checks, and saved responses. Check Fillo plans and limits, Formspree's current account limits, and its Workflow documentation before estimating production usage.

Before you switch

Fillo is not a drop-in endpoint for existing markup. Moving means expressing the form as a Fillo schema and choosing the default, customized, or headless renderer. If the current form is stable and its Formspree workflow already works, that rewrite may have no payoff.

Fillo also starts a new response history. Export any Formspree submissions you need to retain before cutover; they cannot be imported as native Fillo responses with schema versions and delivery state.

What you would need to change

Existing Formspree setup	Expected work
One HTML or React form posting to Formspree	Recreate the fields as a Fillo schema, render it on the same route, and test success and error states
Custom validation and conditional UI	Map each rule to Fillo visibility, validation, pages, or custom field behavior and test every path
Notifications, routing, or integrations	Reconnect each destination as a Fillo notification, webhook, or integration and verify delivery
File uploads and submission history	Preserve the old files and export; connect the new file destination before switching traffic

Next step

From form endpoint to form system

The endpoint isn't the whole backend.

Fillo renders the fields too.
