Form Backend Service

The Form Backend That Does More Than Collect Submissions

Point your HTML form at a Formgrid endpoint and every submission becomes a tracked lead with email notifications, Google Sheets sync, and a follow up pipeline. No backend to build. No server to maintain. Free to start.

Used by 200+ developers, agencies, and teams managing over 10,000 leads monthly. 100% open source.

What Is a Form Backend?

A form backend is the server side infrastructure that receives, stores, and processes the data submitted through your HTML form.

When someone fills out a contact form on your website and clicks submit, their browser sends the data to a URL specified in your form action attribute. Without a backend to receive that request, the data goes nowhere.

Static sites, landing pages, and portfolios built on GitHub Pages, Netlify, Vercel, Cloudflare Pages, or plain HTML have no server side code. They cannot process form submissions on their own.

A form backend service like Formgrid acts as that server. You point your form action at a Formgrid endpoint URL. Every submission is received, stored, and forwarded to you automatically. No server to configure. No database to manage. No backend code to write or maintain.

How Formgrid works

Four steps from zero to production. Step four mentions Google Sheets sync when you want rows without opening your inbox.

Create a form in the dashboard

Name it, pick notification settings, and note the unique endpoint path Formgrid assigns.

Copy the HTTPS endpoint URL

You will paste this value into the action of any HTML form that should post here.

Ship your static HTML unchanged except for the action URL

Jekyll, Hugo, Astro, Eleventy, or hand written pages all behave the same way.

Route submissions to email, the dashboard, and optional Sheets

Turn on Google Sheets sync from the integration screen when your ops team lives in a spreadsheet.

Minimal HTML example

index.html
<form action="https://formgrid.dev/api/f/your-form-id" method="POST">
  <input type="text" name="name" placeholder="Your name" required />
  <input type="email" name="email" placeholder="Email" required />
  <textarea name="message" placeholder="Message"></textarea>
  <button type="submit">Send</button>
</form>

Replace your-form-id with the identifier from your workspace.

UTM Source Tracking

Know exactly which channel sent each submission. Google, Instagram, referrals, and paid ads are captured automatically on every form post.

Spam Protection

Honeypot fields and rate limiting are built in automatically. Your form is protected from bots without any configuration required.

Works with the stacks you already publish

Same integration story everywhere. Designers on Webflow form backend flows and merchants on Squarespace form backend pages point their action URL here too.

Frequently Asked Questions

It is the hosted URL that accepts your HTML form POST, stores fields, and fans out notifications without you operating a server.
No. A plain HTML form with the correct action and method attributes is enough. Add client side validation if you want polish but it is optional.
Netlify Forms is tailored to Netlify hosting detection. Formgrid uses an explicit endpoint URL so the same form works on GitHub Pages, Cloudflare Pages, S3, or any static host you prefer.
Yes. Run the Docker image privately, point DNS at your instance, and keep submissions off shared SaaS infrastructure while still using the same dashboard concepts.
Yes. Honeypot fields and rate limiting run on every plan. CAPTCHA appears when you upgrade to Premium or Business for noisy forms.
