A form backend that's free forever.
500 submissions a month across 10 forms, and no card. Email, Slack, Discord and Telegram delivery are all included on the free plan, and AI-powered spam protection screens every submission before it lands — no server, no database.
10 forms, 500 submissions a month, no card, no expiry. Need more? Starter is $9/mo — less than Formspree or Basin.
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.
Everything a form backend needs — built in
A hosted form submission API with webhooks, email notifications, and AI-powered spam protection included.
