    The Problem

    Why use a form backend instead of building one

    • Building a backend just to handle contact forms
    • Managing email notifications and validation
    • Storing submissions securely at scale
    • Setting up webhooks and automation

    The Solution

    One form endpoint. Zero backend setup.

    Point your form's action attribute to your Formboost endpoint. We handle secure storage, email notifications, webhook delivery, and AI-powered spam filtering — no backend code required.

    Everything a form backend needs — built in

    Formboost is a hosted form submission API for static sites and frontend frameworks. One endpoint collects the submission, AI spam filtering screens it, and email, webhooks and your chat tools deliver it — without a server, a database or a CAPTCHA of your own.

    Free forever on 500 submissions a month across 10 forms. No card, no expiry.

    AI-powered spam protectionAI

    Heuristics screen every plan. From Starter an AI model reads the ambiguous ones in your form's own context and scores them 0–100. No CAPTCHA.

    Changing a form backend is one attribute: point the form's action at your Formboost endpoint. Each guide below compares plans and limits and walks through the swap.

    Frequently asked questions

    What is a form backend?

    A form backend is the server side of a form: the thing that receives a submission, stores it, screens it for spam and delivers it somewhere useful. Formboost is that service, so your HTML, React, Next.js or Vue form posts to one endpoint and you never write an API route, a database table or an email sender.

    Is Formboost really free?

    Yes. The Free plan is free forever: 10 forms and 500 submissions a month, no card and no expiry, with email, Slack, Discord and Telegram delivery included, one destination per form. Paid plans start at $9/mo for higher limits, custom webhooks, Google Sheets, Zapier, n8n and Auto Reply.

    Does it work on a static site with no server?

    That is the main use. A static site on GitHub Pages, Cloudflare Pages, Netlify, Vercel or S3 cannot run code, so its form posts straight to your Formboost endpoint. Afterwards the visitor lands on Formboost's hosted thank-you page, or on a page of your own site if the form sets _redirect.

    What happens to a submission?

    The endpoint validates the request and answers at once: a 302 to your redirect for an HTML form, or a 202 with JSON for a fetch() call. The submission is then queued, checked against your plan's allowance, screened for spam, stored, and delivered to every destination the form has. A slow or failing destination never delays the response or loses the submission.

    Enterprise-ready

    A form backend built for reliability and scale

    Formboost runs on globally distributed infrastructure built for speed, security, and reliability. Your form submission API stays online, your data stays protected, and every submission is processed with the performance your users expect.
