§ 00Gatsby + Waitlistplatform-specific integration guide

Why Gatsby developers choose splitforms for waitlist

Gatsby's static output is excellent for SEO and performance, but static HTML forms have no way to deliver submissions without a backend. Gatsby Cloud offers serverless functions, but wiring SMTP and a dashboard is a substantial project for what should be a simple contact form. The waitlist on this page posts from the browser to splitforms — no Gatsby Function, no API route, no build-time configuration. The form works identically whether you deploy to Gatsby Cloud, Netlify, Cloudflare Pages, or any static host.

§ 00Quick answerReact / Next.js · marketing

Yes — this is the shortest safe path for Gatsby.

Use the React / Next.js snippet on this page, keep the waitlist fields visible in your Gatsby 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 gatsby reality

Gatsby builds a static React app, so 'native' means choosing between (a) Netlify Forms (Gatsby-on-Netlify only, 100 free submissions/month, gatsby-plugin-netlify required), (b) Gatsby Functions (deprecated in Gatsby 5 — they were removed when Gatsby Cloud shut down), or (c) a third-party form backend.

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
01

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.

02

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.

03

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.

§ 03cGatsby production notesnative path · deploy · gotchas

What changes when this waitlist lives in Gatsby.

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

without splitforms

Gatsby builds a static React app, so 'native' means choosing between (a) Netlify Forms (Gatsby-on-Netlify only, 100 free submissions/month, gatsby-plugin-netlify required), (b) Gatsby Functions (deprecated in Gatsby 5 — they were removed when Gatsby Cloud shut down), or (c) a third-party form backend. Gatsby v4 had Functions running as Lambda-equivalent serverless routes; v5 removed them entirely. Result: every Gatsby contact form today uses an external service. Splitforms is a drop-in replacement — same shape as Netlify Forms (POST to a URL), same shape as Formspree, but with 5× the free monthly submissions and built-in spam filtering.

deploy notes

Gatsby builds static HTML + JS that deploys to any host: Netlify, Vercel, Cloudflare Pages, AWS Amplify, S3 + CloudFront, Gatsby Cloud (sunset 2024 — migrate). The form posts cross-origin to splitforms regardless of host. Env vars exposed to the browser bundle must be prefixed GATSBY_ — anything else is undefined client-side. The key gets bundled into the JS at build time; lock it to your domain in the splitforms dashboard. For headless Gatsby + WordPress / Contentful setups, the form lives in the React tree, not the CMS — no special CMS wiring required.

Gatsby gotcha

GATSBY_ prefix required for env vars exposed at build time

Gatsby's webpack config only exposes process.env.* variables prefixed with GATSBY_. If you write process.env.SPLITFORMS_KEY, you'll get undefined in the browser bundle. Rename to GATSBY_SPLITFORMS_KEY — and accept that it's bundled into the static JS (lock the key to your domain in the splitforms dashboard).

Gatsby gotcha

Gatsby's <Link> can't wrap a form's submit handler

Gatsby's <Link> component prevents default navigation. If you wrap your form in <Link to="/thanks"> thinking the redirect will fire, it won't — the form's submit event runs, but the navigation is suppressed. Use a hidden redirect input on the form and let splitforms handle the 302.

Gatsby gotcha

SSR + client hydration mismatch on form initial state

If you use useState('idle') in your form and render any state-dependent UI on first paint, Gatsby's static HTML and React's client render can diverge — you'll see a hydration warning. Render the form unconditionally; only render status messages inside the handler-triggered branches.

Gatsby gotcha

Gatsby v5 partial hydration changed how forms hydrate

Gatsby 5 introduced partial hydration via React Server Components. If your form is in a Server Component, the onSubmit handler won't bind. Add 'use client' at the top of the file (or use a separate ContactForm.client.jsx).

PATTERN A

Pattern A — React component (Gatsby v4/v5)

Standard React function component, useState for status. Drop into src/components/ContactForm.jsx and import on any page. Set GATSBY_SPLITFORMS_KEY in .env.production and .env.development. Use the same wiring for the waitlist fields on this page.

pattern-a.jsxjsx16 lines
01import React, { useState } from "react";
02export default function ContactForm() {
03 const [status, setStatus] = useState("idle");
04 return (
05 <form onSubmit={async (e) => {
06 e.preventDefault(); setStatus("loading");
07 const fd = new FormData(e.target);
08 fd.append("access_key", process.env.GATSBY_SPLITFORMS_KEY);
09 const r = await fetch("https://splitforms.com/api/submit", { method: "POST", body: fd });
10 setStatus((await r.json()).success ? "ok" : "err");
11 }}>
12 <input name="email" type="email" required />
13 <button disabled={status === "loading"}>Send</button>
14 </form>
15 );
16}
PATTERN B

Pattern B — partial hydration (Gatsby v5)

Gatsby 5's partial hydration mounts only the components marked client-bound. Add 'use client' at the top of the form file so the onSubmit handler binds at hydration time; the rest of the page stays static. Use the same wiring for the waitlist fields on this page.

pattern-b.jsxjsx7 lines
01// src/components/ContactForm.jsx
02"use client";
03import React, { useState } from "react";
04export default function ContactForm() {
05 const [status, setStatus] = useState("idle");

§ 06Questions9 answered

Waitlist on GatsbyFAQ.

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

01Does this waitlist work on Gatsby?
Yes. The form is plain HTML with a single POST endpoint, so it runs on any Gatsby site without server-side code, plugins, or SDKs. Drop the snippet into a Gatsby page or component and submissions land in your splitforms dashboard.
02How much does the waitlist cost on Gatsby?
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 Gatsby 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 Gatsby 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.
