About
HeroTofu is a form backend service for static sites and other frontends that need to collect HTML form submissions without writing server-side code. A form posts to a HeroTofu endpoint, and the service handles submission storage, email notifications, Slack and Zapier forwarding, spam filtering, and encrypted archives.
The free plan includes unlimited form endpoints, 25 form submissions per month, form spam protection, and email notifications. The pricing page also states a 14-day free trial of the Business plan with no credit card required, after which accounts downgrade to the free tier automatically if no subscription is chosen.
- Unlimited form endpoints

Free Tier Value
This free tier is a capped but genuinely usable starter plan: it includes unlimited endpoints and popups/banners, but the practical limits are tight at 25 submissions per month, 1 recipient, and a short archive window. The cheapest paid plan is about $8.33/month billed yearly, so the free tier is worth roughly 25% of that — about $2/month — and the 14-day trial is available with no credit card required before it drops back to the free plan.
What's included in the free tier
- Unlimited form endpoints.
- 25 form submissions per month.
- Form spam protection.
- Email notifications with 1 recipient.
- 30-day submissions archive.
