    The Problem

    Form submissions shouldn't require a full backend

    • 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 API 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.

    See how it works

    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.
