§ 00Astro + Feedback Formplatform-specific integration guide

Why Astro developers choose splitforms for feedback form

Astro's static-first architecture means your form HTML ships pre-rendered with zero client JavaScript — perfect for fast page loads, but it also means you can't call a server-side endpoint on static hosts. splitforms is designed for exactly this: the browser POSTs directly to our edge endpoint, so the form works on Netlify, Cloudflare Pages, Vercel, or any static host without an Astro API route. The feedback form is pure HTML — no <code>&lt;script&gt;</code> tag, no client component, no island. Astro's view transitions and partial hydration don't interfere with the form submission because it uses a standard browser POST.

§ 00Quick answerHTML · feedback

Yes — this is the shortest safe path for Astro.

Use the HTML snippet on this page, keep the feedback form fields visible in your Astro UI, and let splitforms handle delivery, spam filtering, storage, and webhooks.

best implementation

Paste the HTML 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?.

Astro's whole pitch is shipping zero JavaScript by default.

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
01

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.

02

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.

03

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.

§ 03cAstro production notesnative path · deploy · gotchas

What changes when this feedback form lives in Astro.

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

without splitforms

Astro's whole pitch is shipping zero JavaScript by default. A native contact form on Astro means either (a) building a form with no submission target — useless — or (b) standing up an API endpoint via output: 'server' or 'hybrid', which means writing a Node/Bun/Deno handler, picking an email provider, writing your own honeypot logic. Astro 5 added typed Actions, but they're a wrapper around the same underlying fetch — you still deliver the email yourself. The result: every Astro contact-form tutorial ends with 'now configure SendGrid'. Splitforms is the SendGrid-replacement that doesn't require an account, an API key for the email provider, or DNS records for SPF/DKIM.

deploy notes

Astro deploys cleanly to Vercel, Netlify, Cloudflare Pages, GitHub Pages, and any static host with output: 'static'. For Astro Actions (Pattern B), you need output: 'server' or 'hybrid' and a matching adapter (@astrojs/vercel, @astrojs/netlify, @astrojs/cloudflare). On Cloudflare Pages with the Cloudflare adapter, the Action runs in a Worker — keep the splitforms fetch tight (no extra proxying) to stay under the 10ms CPU budget on the free plan. The PUBLIC_ prefix is mandatory for env vars exposed to client-rendered .astro files; vars without it are silently undefined. Lock the key to your *.pages.dev and custom domain.

Astro gotcha

PUBLIC_ prefix is required for client-exposed env vars

Astro mirrors Vite's env-var convention: only variables prefixed with PUBLIC_ are exposed to client-side code (and to .astro files when output: 'static'). If you write import.meta.env.SPLITFORMS_KEY, you'll get undefined at build time. Rename to PUBLIC_SPLITFORMS_KEY.

Astro gotcha

client:load on the form island defeats the point of Astro

If you wrap the form in <MyForm client:load />, you ship a full React/Preact runtime just for one form. Use client:visible (load when scrolled into view) or client:idle (load after main thread is free) instead. For zero-JS forms, skip the island entirely and use a plain HTML form action.

Astro gotcha

Astro Actions need a try/catch or they crash the page

If your action throws, Astro 5's behavior is to render an error page rather than return the error to your form. Wrap the splitforms fetch in try/catch and return { success: false, message } from the action — your form component can then render the message.

Astro gotcha

View Transitions can break form re-submit state

If you've enabled <ViewTransitions /> in your layout, navigating to /contact and back may re-mount the form mid-submission. Add data-astro-reload to the form's submit anchor or guard with if (status === 'loading') return at the top of your handler.

PATTERN A

Pattern A — pure HTML form (zero JS shipped)

The Astro-native approach: a .astro file with frontmatter pulling the key from import.meta.env, then a static <form action> that posts directly. Zero hydration, zero island, zero KB JavaScript. Use the same wiring for the feedback form fields on this page.

08 <textarea name="message" required />
09 <button type="submit">Send</button>
10</form>
PATTERN B

Pattern B — Astro Action for typed server-side proxying

Astro 5 Actions give you Zod-validated, type-safe form handlers. Use one to keep the access key off the client entirely — the form posts to the action, the action proxies to splitforms. Use the same wiring for the feedback form fields on this page.

§ 06Questions9 answered

Feedback Form on AstroFAQ.

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

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