Form backend for any website

FORMCORE

Point your form at Formcore and start collecting submissions.

How it works

Simple by default.
Flexible when you need it.

Add one endpoint and keep your existing frontend. Start with plain HTML, then scale to Next.js, SvelteKit, Astro, React, or custom flows without reworking your backend.

<form action="http://formcore.io/f/YOUR_FORM_ID" method="POST">
  <input type="text" name="name" required />
  <input type="email" name="email" required />
  <button type="submit">Submit</button>
</form>

fetch("http://formcore.io/f/YOUR_FORM_ID", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({ name: "Jane", email: "[email protected]" })
});

curl -X POST http://formcore.io/f/YOUR_FORM_ID \
  -H "Content-Type: application/json" \
  -d '{"name": "Jane", "email": "[email protected]"}'

{"status": "ok"}
