FormSubmit: The form backend for any website

Overview

FormSubmit provides a serverless backend service designed for anyone who needs a form submission handler without managing server code. It works with virtually any HTML form or sites built with WordPress, React, Next.js, Vue, or static site generators like Hugo or Jekyll. Instead of creating a custom backend, you assign your form’s action attribute to a unique FormSubmit URL, and submissions are sent directly to your inbox or integrated apps.

FormSubmit handles the full submission workflow: emails arrive in a clear, readable format; spam is filtered out automatically using honeypots, timing checks, and optional captchas; file uploads are securely stored and shared through signed links; and data can be forwarded to webhooks, Slack, Discord, or Google Sheets with minimal permission scopes. The service provides a visual form builder for quick setup and supports AJAX submission with JSON responses for interactive experiences. Plans range from a free tier with basic limits to paid options that increase submission capacity and storage.

By separating form frontends from backends, FormSubmit fits the JAMstack and static site ethos, solving the common problem of handling forms on sites without servers. The solution focuses on privacy with encrypted secrets and configurable data retention policies. We went through the site and it says you can get started in about a minute by creating a form, pointing it at an endpoint, and receiving submissions via email or integrations.
