The form backend for your frontend.
formbuild.io gives any form a secure submission endpoint. Add it to an HTML form, React or Next.js app, static site, or an AI-generated website, and receive submissions by email, Slack, Discord, or webhook — no backend to build.
Why we built it
Every website eventually needs to collect something — a contact message, a signup, a piece of feedback. Doing that has always meant standing up a server, a database, and spam handling just to receive a few fields. formbuild.io removes that step: you point your form at one secure endpoint and start receiving responses in minutes, whether your site is hand-written HTML, a React app, or generated by an AI tool like v0.
What it does
formbuild.io accepts submissions from any origin, validates them server-side, filters spam, and delivers them to you by email and — on Pro — Slack, Discord, and signed webhooks. It works with plain HTML forms and with fetch() on HTML, React, Next.js, Vue, Svelte, Astro, Vercel, Netlify, and more.
How it's run
formbuild.io is a hosted service — there is nothing to self-host. We treat your data carefully: connections are encrypted in transit, passwords are hashed with Argon2id, and you can export or delete your data at any time. See our security page and privacy policy for details.
