Free form backend for static sites and frontend apps.
Point any HTML form at splitforms and receive submissions in your inbox and dashboard. No PHP, no SMTP server, no serverless function, no plugin lock-in.
One endpoint is the whole backend.
The browser submits the form. splitforms validates, filters, stores, emails, and forwards the payload. Your site stays static.

What is a form backend?
A form backend is the server-side receiver for a website form. It accepts the POST request, validates the fields, filters spam, stores the submission, emails the owner, and forwards the data to webhooks or integrations.
Is splitforms a free form backend?
Yes. splitforms includes 1,000 submissions per month, unlimited forms, dashboard storage, email notifications, signed webhooks, file uploads, CSV export, and spam filtering on the free plan. No credit card is required.
Does this work with static sites?
Yes. splitforms works with plain HTML, GitHub Pages, Astro, Hugo, Eleventy, Jekyll, Next.js, React, Vue, Svelte, Webflow, Carrd, Framer, and WordPress because the integration is just a standard form action URL.
How is this different from Formspree, Web3Forms, Getform, or Basin?
splitforms is built as a developer-first form backend with a larger free tier than most alternatives, unlimited forms, dashboard storage, signed webhooks, file uploads, AI spam filtering, and a $5/month Pro plan.
