The developer-first form submission API
A serverless form backend for developers. Point any HTML form to your API endpoint and get email notifications, real-time webhooks, and AI-powered spam protection without writing a single line of backend code.
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 spam filtering — no backend code required.
Everything a form backend needs — built in
A hosted form submission API with webhooks, email notifications, and spam protection included.
Serverless form service
Point any HTML form to your endpoint. Works with static sites, Next.js, SvelteKit, Astro, and every frontend stack. No server setup required.
REST API & webhooks
Full form submission API for custom integrations. Configure webhook endpoints to receive real-time POST events on every submission.
