Static site contact form
Point a plain HTML form at one hosted endpoint and every submission lands in your inbox and dashboard — no serverless function, PHP, or SMTP.
No serverless function, Worker, PHP, or SMTP — the endpoint is the backend.
Honeypot, time-trap, and rate limits screen bots before your inbox.
Every submission is stored and emailed to you within seconds.
Copy-paste ready
Drop this into any static template, point the action at the endpoint, and add your access key. That's the whole integration — no build step, serverless function, or SMTP.
<form action="https://splitforms.com/api/submit" method="POST">
<input type="hidden" name="access_key" value="YOUR_ACCESS_KEY" />
<input type="hidden" name="redirect" value="https://yoursite.com/thanks" />
<input name="name" placeholder="Name" required />
<input name="email" type="email" placeholder="Email" required />
<textarea name="message" placeholder="Message" required></textarea>
<input type="checkbox" name="botcheck" style="display:none" tabindex="-1" />
<button type="submit">Send message</button>
</form>How to add it
Five steps, no server code of your own — the same path works whether your site is pure HTML or a generator like Hugo or Astro.
Sign up and create a form in the dashboard. Free covers 500 submissions a month on unlimited forms, with email notifications and spam filtering included and no credit card required. Copy the form's access_key.
Add a plain <form action="https://splitforms.com/api/submit" method="POST"> to your GitHub Pages, Astro, Hugo, Eleventy, or Jekyll template — no build step, API route, or serverless function required.
Set access_key as a hidden field so splitforms knows which form is submitting, add a redirect field with your thank-you page URL, and include a hidden botcheck input that must stay empty to catch bots.
Push to GitHub Pages, Netlify, Cloudflare Pages, S3, or your host of choice. The form posts directly to splitforms, so there is nothing server-side to configure on the host itself.
Submit the live form once. Confirm the lead lands in your inbox and the splitforms dashboard, then turn on allowed-domains or strict origin mode in the form's settings to block spoofed submissions from other sites.
How it works
Static hosts can't process POST requests themselves — they only serve files. splitforms sends the browser's POST straight to a hosted form endpoint built for that job, so nothing runs on your host: every submission is filtered, stored, and delivered to your inbox.
Spam protection
splitforms layers three defenses that all work on a purely static page — no CAPTCHA required. If your site can run one line of JavaScript, add a form_loaded_at hidden field as a time-trap, and optional reCAPTCHA v2 is available as an extra layer. Per-form allowed-domains or strict origin mode blocks other sites from reusing your access_key.
Optional fetch
Yes. An Astro island, an Eleventy page with a small script, or a plain <script> tag can POST the same form with fetch() and an Accept: application/json header to show an inline success message instead of redirecting. The HTML action and the fetch call hit the same endpoint, so you can start with the plain form above and upgrade later without renaming a field — see the API reference for the response shape.

Testimonials
40 quotes on record — from indie hacks to agency migrations.
“I replaced a Lambda + DynamoDB + SES contact form with six lines of HTML. It took eleven minutes, and the dashboard is better than what I was going to build.”
“We migrated 14 client sites off Formspree in a single weekend. The price is a third of what we paid, the API is more honest, and the spam filter actually works.”
“The webhook payload is signed, idempotent, and well-shaped. It reads like code from a competent team, not a CRUD app held together with duct tape.”
“I stopped reaching for Typeform on small marketing sites. splitforms covers 90% of the use case at none of the bloat.”
“I onboarded our whole agency in an afternoon. The MCP integration meant Cursor literally dropped the form straight into our client repos for us.”
“The free plan gave me 500 submissions before I paid a cent, and Pro is five dollars a month. I've spent more on coffee deciding which backend to use.”
“Spam went from forty junk entries a day to zero, with no reCAPTCHA puzzle ruining the form. The honeypot and time-trap just quietly do their job.”
“Point the form action at one endpoint and you're done. No SDK, no client library, no build step. This is how a form backend should feel.”
“Leads land in Slack the second someone submits, and a copy goes to Google Sheets for the sales team. I wired both up in under ten minutes.”
“I run a static Hugo site on a five-dollar VPS. splitforms gave it a real contact form without me standing up a single server.”
Questions
Add a normal HTML form that POSTs to https://splitforms.com/api/submit, with a hidden access_key field identifying which splitforms form receives it. No serverless function, PHP, or SMTP setup is needed — submissions land in your inbox and the splitforms dashboard.
Yes. GitHub Pages only serves static files and can't run a form handler, but it can still POST to an external endpoint. Point the form's action at splitforms and it works the same way on Jekyll, Hugo, Eleventy, or any other static host.
No. A native HTML form submit works with zero JavaScript, and the botcheck honeypot field filters spam without any script running. Add a line of JavaScript only if you want the optional form_loaded_at time-trap field or a fetch-based inline success message — neither is required.
splitforms layers static-friendly defenses: a hidden botcheck honeypot field that must stay empty, server-side content heuristics on every submission, and rate limiting of 6 submissions a minute and 20 per 15 minutes per IP. Add the form_loaded_at time-trap field or optional reCAPTCHA v2 for extra coverage — none of it requires a JavaScript framework.
Yes. POST a FormData body to https://splitforms.com/api/submit with an Accept: application/json header from a fetch() call, and splitforms returns a JSON response you can use to show an inline success message instead of redirecting the page.
Yes. Free covers 500 submissions a month across unlimited forms, with email notifications, spam filtering, and dashboard storage included — no credit card required. Pro ($5/mo) adds CSV/XML/PDF exports, webhooks, integrations, and auto-responder at 1,000 submissions a month.
Yes. Add hidden subject, redirect, and replyto fields to the form. subject sets the notification email's subject line, redirect sends visitors to your thank-you page after submit, and replyto sets the reply-to address so you can respond directly from your inbox.
