§ 00Gatsby + Feedback Formplatform-specific integration guide

Why Gatsby developers choose splitforms for feedback form

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 feedback form 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 · feedback

Yes — this is the shortest safe path for Gatsby.

Use the React / Next.js snippet on this page, keep the feedback form 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 how would you rate your experience?, what can we do better?, email (optional, for follow-up). Required fields are how would you rate your experience? and what can we do better?.

native gatsby reality

use case fit

Customer feedback is the cheapest product research you have. The form captures NPS / CSAT plus an open comment — and routes negative responses to a Slack channel for same-day triage.

§ 03bCustomer Feedback Form (NPS / CSAT / Open-Ended)template-specific playbook

The reason this feedback form exists.

Webhooks into Slack / Linear / Productboard · NPS detractor triage in minutes.

why it matters

Feedback forms cost almost nothing to ship and pay back disproportionately — every NPS detractor (score 0-6) is a conversation that prevents churn, every promoter (9-10) is a referral or testimonial source. The form is simple: 0-10 rating, an optional comment, and an email. The leverage is in the routing: detractors auto-DM your support lead in Slack within minutes, promoters get a 'mind leaving us a G2 / Trustpilot review?' follow-up, passives go into a digest. Survey tools (SurveyMonkey, Typeform, Hotjar) charge $30-100/mo for the same pattern. The form pattern is 30 lines of HTML.

route the submission

Capture rating + comment

Required: 0-10 NPS rating (or 1-5 CSAT for transactional surveys). Optional: comment textarea, email for follow-up. Keep it minimal — long surveys tank completion.

Route by score

Webhook branches on score: 0-6 (detractors) DM Slack support channel; 7-8 (passives) go to weekly digest; 9-10 (promoters) trigger a G2 / Trustpilot review-request email.

Push to your tools

Detractor comments to Linear / Productboard for product triage. Promoter quotes to a 'testimonials' Notion database for marketing. Raw data to a CSV / BigQuery / dbt warehouse for trend analysis.

§ 03cGatsby production notesnative path · deploy · gotchas

What changes when this feedback form 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 feedback form 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 feedback form fields on this page.

pattern-b.jsxjsx7 lines

01// src/components/ContactForm.jsx
02"use client";
03import React, { useState } from "react";

§ 06Questions9 answered

Feedback Form on Gatsby — FAQ.

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

01Does this feedback form 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 feedback form 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 (how would you rate your experience?, what can we do better?, email (optional, for follow-up)…) — add, remove, or rename any of them. Splitforms accepts whatever fields you POST.

04How does spam protection work on the feedback form?

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 feedback form 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 use NPS or CSAT?

NPS (0-10) for relationship surveys ('how likely are you to recommend us?') sent quarterly or after major moments. CSAT (1-5) for transactional surveys ('how was this support ticket?') sent right after the interaction. Different questions, different cadences, both common patterns.

08Will I get response bias from a public form?

Yes — open-link feedback skews toward people with strong feelings (positive or negative). For statistically representative measurement, send the survey via email to a random sample of users. The public form catches the heat-of-moment feedback you'd otherwise miss.

09Can I push to Slack / Linear / Productboard?

Yes — webhook the JSON. Slack has incoming webhooks (free); Linear and Productboard accept inbound issue creation via Zapier or native APIs. Detractor comments showing up as a Linear issue with the rating prefilled in the title is a powerful workflow.
