Contact form · Vercel
Contact form for Vercel-hosted sites
Vercel has no built-in form handler — every form needs a backend API route or third-party service. splitforms is the cheapest path: direct POST from any Vercel deploy (Next.js, SvelteKit, Astro, Nuxt, static) with no /api route required.
- 500 free / mo
- 14ms latency
- No backend code
No backend code
No server, API route, or SDK. Your Vercel form posts straight to one endpoint.
Straight to your inbox
Every submission is emailed to you and saved to a searchable dashboard — spam filtered before it reaches you.
Design without limits
It's your own Vercel markup and styles. Splitforms is only the backend, so nothing constrains how the form looks.
Copy-paste ready
Your Vercel contact form, ready to paste.
Replace YOUR_ACCESS_KEY with the key from your dashboard — that's the whole integration. No SDK to install, no build step, just the html you already write.
<!-- Works in any Vercel deploy: Next.js, SvelteKit, Astro, Nuxt, static -->
<form action="https://splitforms.com/api/submit" method="POST">
<input type="hidden" name="access_key" value="YOUR_ACCESS_KEY" />
<input name="name" required />
<input name="email" type="email" required />
<textarea name="message" required></textarea>
<input type="checkbox" name="botcheck" style="display:none" tabindex="-1" />
<button type="submit">Send</button>
</form>
<!--
No /api/contact.ts route needed. The form POSTs directly to splitforms.
Saves you a Vercel Function invocation (matters on the Hobby plan).
If you prefer to hide the key, see the Next.js page for a Server Action
pattern that keeps the key server-side.
-->How to add it
How to add a contact form to a Vercel website.
To add a contact form to a Vercel website you need three things: a free splitforms access key, the html snippet above, and your key pasted into it. No backend, server, or SDK — the form posts to one URL and every submission lands in your inbox and dashboard.
Drop the Vercel snippet into your project
Copy the Vercel code example into your project and replace YOUR_ACCESS_KEY with the key from step 1.
Receive submissions in your dashboard
Submissions arrive in the splitforms dashboard within seconds. Free includes inbox delivery; Pro adds Slack, Discord, Sheets, or any signed webhook URL.
Where submissions go
Where do your Vercel form submissions go?
Every submission is emailed to you and saved to a searchable dashboard — spam filtered before it ever reaches you. Search, export to CSV, or forward it to a webhook or Slack on Pro.
- 500 submissions per month, free forever
- Honeypot + AI spam classifier on every plan
- Signed webhooks to Slack, Discord, your server
No backend needed
Do you need a backend for a Vercel form? No.
Your Vercel form posts standard FormData to one URL. Splitforms validates the access key, runs the spam classifier, and forwards it to your email — so there's no server, API route, or database for you to build or maintain.
- No /api route required — saves Vercel Function invocations on Hobby
- Works with every Vercel framework preset (Next.js, SvelteKit, Astro, Nuxt)
- Optional Server Action pattern if you want the key off the client
Best practices
What a production-ready Vercel form needs.
The difference between a form that works in the demo and one that survives launch traffic — the production-tested defaults, in priority order.
- Lock the access key to your domains. The dashboard accepts a list — anyone copying the key from your bundle can't replay it from another origin.
- Add the hidden honeypot input. Bots fill every field; humans don't see it. Splitforms rejects any submission that has it set.
- Show submit state visually. Disable the button and label it 'Sending…' while the request is in flight — users hammer submit on slow networks otherwise.

Testimonials
Loved by developers shipping at every scale.
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
Vercel contact form questions.
View all FAQsIs splitforms really free?
Yes — 500 dashboard submissions per month forever, no credit card. Pro is $5/mo for delivery features and retained uploads when Storage is connected; Pro is $5/mo for 5,000 submissions.
Do I need to install anything?
No. Splitforms is API-only. There's no SDK, no plugin, no PHP. Your form posts standard FormData to one URL.
How do you handle spam?
A hidden honeypot field catches the obvious bots. A tuned classifier scores everything else and quarantines the noise. You see clean submissions only.
Can I keep my access key out of the bundle?
Yes — use a server-side environment variable and post from a server route or server action. Or expose it client-side and rely on per-domain locking. Either path is supported.
How does Vercel handle forms without splitforms?
Hand-rolling a contact form on Vercel means building the whole pipeline yourself: an app/api/contact/route.ts handler, an email provider like Resend, Postmark, or AWS SES, environment variables for the SMTP or API keys, your own spam protection, somewhere to store submissions (Vercel KV, Supabase, a database), and a dashboard to actually read them. That's a weekend of glue code for a single form. A direct POST to splitforms replaces every piece — and because it happens client-side, your deploy can stay a static export with zero Function invocations.
