§ 00Quick answerHTML · feedback

Yes — this is the shortest safe path for Vercel.

Use the HTML snippet on this page, keep the feedback form fields visible in your Vercel 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?.

native vercel reality

Vercel can render the form markup, but it still needs a backend endpoint, email delivery, spam checks, and webhook routing before submissions are useful.

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.

Loved the demo — quick question about pricing on the 4-year plan. Are usage limits per project or account-wide?

§ 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.

§ 06Questions9 answered

Feedback Form on Vercel — FAQ.

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

01Does this feedback form work on Vercel?

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

02How much does the feedback form cost on Vercel?

Free for 1,000 submissions per month — no credit card, no trial. Pro is $5/mo for 5,000 submissions, and there's a one-time $59 4-year plan (15,000 submissions/mo for 48 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 Vercel as on any other framework.

05Can I send the feedback form submissions to Slack or Discord?

Yes. Webhooks are free on every plan, 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 Vercel 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.
