§ 00Next.js + Waitlistplatform-specific integration guide

Why Next.js developers choose splitforms for waitlist

Next.js Server Actions handle the submit side but still leave you wiring SMTP, spam filtering, file uploads, and a dashboard. splitforms replaces all of that with one <code>fetch('/api/submit')</code> call. The waitlist works identically in App Router and Pages Router — it's just a <code>FormData</code> POST, no router-specific magic. Because Next.js pre-renders pages, the form HTML is in the DOM before any JavaScript executes, meaning instant Time-to-Interactive. The honeypot field is invisible to users but catches bots that scrape rendered HTML — especially important for Next.js sites where the form HTML is statically generated and predictable.

§ 00Quick answerReact / Next.js · marketing

Yes — this is the shortest safe path for Next.js.

Use the React / Next.js snippet on this page, keep the waitlist fields visible in your Next.js UI, and let splitforms handle delivery, spam filtering, storage, and webhooks.

best implementation

Paste the React / Next.js version, then replace YOUR_ACCESS_KEY.

The posted payload contains email, name, how did you hear about us?. Required fields are email.

native next.js reality

use case fit

Pre-launch waitlists let you capture demand before the product ships. The multi-step form qualifies the use case so launch-day conversions skew toward the highest-intent signups.

§ 03bWaitlist Signup Form (Pre-Launch Lead Capture)template-specific playbook

The reason this waitlist exists.

Multi-step (Typeform-style) · webhooks into Loops / ConvertKit / Beehiiv.

why it matters

Waitlists are the cheapest growth tool a pre-launch product has — Superhuman, Notion, and Linear all built sizable waitlists before paid launch. The form captures email plus a question or two on use case ('what would you use this for?', 'what tools do you use today?') so the launch sequence segments by intent. Multi-step flow boosts completion vs a single form — the prospect commits in step 1 and answers the qualifying questions in step 2-3 with momentum. Push waitlist signups to a dedicated ESP audience (Loops, ConvertKit, Beehiiv) so launch-day emails segment by use case and target the highest-intent signups first.

route the submission

Step 1: capture email

Single email field — keep step 1 frictionless. Loss-rate from email-only is near-zero; once the email is in, momentum carries through later qualifying questions.

Step 2-3: qualify use case

One or two questions on use case ('what problem brings you here?', 'what tools do you use today?'). Optional but most users complete because they're invested by step 2.

Push to ESP segment

Webhook to Loops / ConvertKit / Beehiiv / Mailchimp into a 'waitlist' audience. Launch-day emails segment by use case so the highest-intent signups get the first invite waves.

§ 03cNext.js production notesnative path · deploy · gotchas

What changes when this waitlist lives in Next.js.

These notes come from the Next.js platform registry and are rendered on this template page so crawlers see the framework-specific answer without opening a separate guide.

without splitforms

Without splitforms, you'd write a route handler at app/api/contact/route.ts, parse the FormData, configure SMTP via nodemailer or Resend (~10 minutes of secrets wrangling), add a Postgres or SQLite store for submissions, and then bolt on rate limiting, a honeypot check, an email-classifier or reCAPTCHA, and webhook fan-out. Server actions made the wiring slightly tidier in Next 14+, but the operational cost stays the same: a function with a runtime, a database, an outbound email provider, an inbox to monitor, and your name on the spam-filter incident report. Splitforms collapses all of that into a POST to a single URL.

deploy notes

On Vercel, the form works on every plan tier — server actions and client components both run inside the same edge/serverless function. Don't put the splitforms fetch inside a Vercel cron or background function (it's user-facing, latency matters). On Netlify with the Next runtime, server actions need the latest @netlify/plugin-nextjs (≥5.6). For self-hosted / Docker: configure output: 'standalone' in next.config.ts and pass SPLITFORMS_KEY as a runtime env var — never bake it into the image. For static export (output: 'export'), use the client-component path only — server actions aren't supported in static mode.

Next.js gotcha

Don't expose your access key client-side without domain locking

Inlining access_key in a "use client" component makes the key visible to anyone who views source. That's fine if you've enabled allowed-domains in your Splitforms dashboard (Settings → Security) — anyone copying the key from your bundle can't use it from a different origin. If you haven't, use a server action so the key stays on the server.

Next.js gotcha

Server actions need `'use server'` and a real form, not fetch

If you submit to a server action via <form action={myAction}>, Next handles the FormData serialization for you. If you call the action manually with fetch, you have to set the right Content-Type and stringify yourself. Pick one path and stick with it — mixing causes 'Server Action invalid' errors.

Next.js gotcha

App Router + Suspense + useSearchParams = static-prerender bailout

If your form reads ?next=/something to support post-submit redirects, useSearchParams forces the page out of static generation. Either wrap the inner component in a <Suspense fallback={<Skeleton/>}> so the wrapper still prerenders, or accept dynamic rendering for the form route only.

Next.js gotcha

Vercel Edge runtime can't read FormData from `multipart/form-data`

If your route handler uses export const runtime = 'edge' and the form posts as multipart (file inputs), it'll silently miss fields. Use application/x-www-form-urlencoded or remove the edge runtime declaration.

PATTERN A

Pattern A — server action (no client JS, key stays server-side)

Form posts to a server action; the action appends the access key from process.env.SPLITFORMS_KEY and proxies to splitforms. Works without JavaScript, key never reaches the bundle. Use the same wiring for the waitlist fields on this page.

pattern-a.tsxtsx10 lines

01// app/actions/contact.ts
02"use server";
03import { redirect } from "next/navigation";
04 
05export async function submitContact(formData: FormData) {
06  formData.append("access_key", process.env.SPLITFORMS_KEY!);
07  const res = await fetch("https://splitforms.com/api/submit", { method: "POST", body: formData });
08  if (!(await res.json()).success) throw new Error("Submission failed");
09  redirect("/thanks");
10}

PATTERN B

Pattern B — client component with fetch and inline status

'use client' component using useState for a 4-state status machine. Lets you show a spinner, inline errors, optimistic resets — at the cost of a hydration boundary. Use NEXT_PUBLIC_SPLITFORMS_KEY and rely on splitforms' domain-locking for safety. Use the same wiring for the waitlist fields on this page.

pattern-b.tsxtsx17 lines

01"use client";
02import { useState } from "react";
03export default function ContactForm() {
04  const [s, setS] = useState<"idle" | "loading" | "ok" | "err">("idle");
05  return (
06    <form onSubmit={async (e) => {
07      e.preventDefault(); setS("loading");
08      const fd = new FormData(e.currentTarget);
09      fd.append("access_key", process.env.NEXT_PUBLIC_SPLITFORMS_KEY!);
10      const r = await fetch("https://splitforms.com/api/submit", { method: "POST", body: fd });
11      setS((await r.json()).success ? "ok" : "err");
12    }}>
13      <input name="email" type="email" required />
14      <button disabled={s === "loading"}>{s === "loading" ? "…" : "Send"}</button>
15    </form>

The same waitlist template works on every framework splitforms supports. Pick yours.

§ 06Questions9 answered

Waitlist on Next.js — FAQ.

Direct answers, no marketing fluff. Missing one? Email hello@splitforms.com.

01Does this waitlist work on Next.js?

Yes. The form is plain HTML with a single POST endpoint, so it runs on any Next.js site without server-side code, plugins, or SDKs. Drop the snippet into a Next.js page or component and submissions land in your splitforms dashboard.

02How much does the waitlist cost on Next.js?

Free for 500 submissions per month — no credit card, no trial. Pro is $5/mo for 5,000 submissions, and there's a one-time $59 3-year plan (15,000 submissions/mo for 36 months). The same pricing applies regardless of which framework hosts the form.

03Can I customize the fields?

Yes. The template ships with sensible defaults (email, name, how did you hear about us?…) — add, remove, or rename any of them. Splitforms accepts whatever fields you POST.

04How does spam protection work on the waitlist?

A hidden honeypot field catches dumb bots, and a tuned classifier scores the rest. You only see real submissions in your dashboard. No CAPTCHA, no friction for human users — and it works the same on Next.js as on any other framework.

05Can I send the waitlist submissions to Slack or Discord?

Yes. Webhooks are available on Starter and above, with auto-formatted payloads for Slack, Discord, and WhatsApp (via CallMeBot). Or send raw signed JSON to any URL — Zapier, n8n, your own server. Configure in the splitforms dashboard.

06Will it work on a static Next.js site?

Yes — the form posts directly to splitforms from the browser, so no server is involved. Works on Vercel, Netlify, GitHub Pages, Cloudflare Pages, S3, or any plain Apache host.

07Should I show waitlist position / numbers?

Showing 'you're #347 in line' on the confirmation creates social proof but invites comparison. Showing total waitlist size ('join 2,500 people on the waitlist') without per-person position is the safer middle. Refer-a-friend mechanics that move people up the list (Robinhood-style) drive viral growth but require more eng work.

08How do I trigger launch invites in waves?

Tag waitlist signups by use case in the ESP audience (Loops, ConvertKit). Launch-day, segment by tag and send invite waves over 48-72 hours. Highest-intent / closest-fit goes first; broadest casts go last. Spreads server load and lets you triage onboarding support.

09Can I integrate with Loops / ConvertKit / Beehiiv?

Yes — webhook the JSON. Loops has direct webhook support and is purpose-built for product transactional + waitlist email. ConvertKit and Beehiiv accept via API or Zapier. All three handle the launch-sequence segmentation cleanly.
