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 shortest path: direct POST from any Vercel deploy (Next.js, SvelteKit, Astro, Nuxt, static) with no /api route required.

- One endpoint
- 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 owner email notification attempts; 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 total, free to start
- Honeypot + automatic spam scoring 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 its spam checks, 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.
How SplitForms works
What happens after someone submits your form?
splitforms receives the submission, filters spam, saves it to your dashboard and emails you — then, on paid plans, sends it on to your webhooks and integrations. No backend infrastructure to build.
Add your endpoint
Point your form to your unique SplitForms endpoint. That's it.
Receive submissions
We instantly capture and organize every submission in your inbox.
Route anywhere
Send data to email, spreadsheets, CRMs, webhooks, and 7,000+ apps.
No credit card required. Set up in under 60 seconds.
Connect & automate
Where can submissions go besides email?
On paid plans, submissions can also go to Slack, Discord, Google Sheets, Notion, Airtable, Zapier or any signed webhook — and splitforms works on the platforms you build on, from WordPress and Shopify to Next.js. With Stripe connected, your forms can take payments too.
NewTake payments on your formsDeposits, bookings, order forms — submitters check out through Stripe and the money goes straight to your Stripe account. Included on every paid plan.See plans →Questions
Vercel contact form questions.
View all FAQsIs splitforms really free?
Yes. You get 500 free submissions with no credit card and no time limit, plus unlimited forms, spam filtering, the dashboard, and owner email delivery. The 500 is a one-time allowance rather than a monthly one. Pro is $5/mo for 5,000 submissions a month and adds signed webhooks, exports, integrations, and retained uploads when Storage is connected.
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 rule-based filter scores everything else (links, spam phrases, disposable emails, gibberish) and quarantines what looks like spam to a separate Spam tab, so your inbox stays clean and nothing is lost.
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.
