Build the 0-10 rating scale
Eleven radio buttons (values 0 through 10) styled inline. Add CSS-only labeling so each number is clickable and keyboard-navigable.
Form template · Feedback
An NPS survey form with the standard 0-10 likelihood-to-recommend question plus an open-ended follow-up. Pure HTML radio scale, no survey-software dependency.
Every template is free and fully editable in the drag-drop builder — swap fields, colors, and the button label before you publish.
No server, API route, or SDK — your NPS Survey Form posts straight to one endpoint.
Every submission is emailed to you and saved to a searchable dashboard — spam filtered before it reaches you.
It's plain HTML you own — paste the NPS Survey Form snippet, swap in your access key, and ship.
Copy and ship
HTML by default — the same field set also renders as React, Next.js, PHP, and cURL in your dashboard. Every variant posts to the same /api/submit endpoint. Replace YOUR_ACCESS_KEY with the key from your dashboard; that's the only edit.

</p>How to add it
To add a NPS Survey Form to your site you need three things: a free splitforms access key, the HTML snippet above, and your key pasted into it. No backend, database, or CAPTCHA library — the form posts to one URL and every submission lands in your inbox and dashboard.
Eleven radio buttons (values 0 through 10) styled inline. Add CSS-only labeling so each number is clickable and keyboard-navigable.
A textarea labeled 'What's the main reason for your score?' — the open-ended part is where the real insight lives.
Submissions land in your dashboard with the score as a number — export to CSV, calculate NPS in a spreadsheet, or webhook into your analytics stack.
What's included
NPS is one of the few customer-feedback metrics that survived its own hype cycle. The standard form is simple — a 0-10 rating and one open-ended follow-up. You don't need Typeform or SurveyMonkey to ship it; an HTML radio scale and a textarea do the job. Calculate NPS in a spreadsheet from the exported submissions: % Promoters (9-10) − % Detractors (0-6). 0-10 scale, open follow-up, NPS calculation in two spreadsheet formulas.

Where submissions go
Reply-to is wired to the visitor's email, so one tap on Reply answers them directly — while the built-in honeypot and spam classifier filter out bots before they reach you. Every submission is emailed to your inbox and can forward to a webhook or Slack the moment a visitor hits send.

Testimonials
40 quotes on record — from indie hacks to agency migrations.
“I replaced a Lambda + DynamoDB + SES contact form with six lines of HTML. It took eleven minutes, and the dashboard is better than what I was going to build.”
“We migrated 14 client sites off Formspree in a single weekend. The price is a third of what we paid, the API is more honest, and the spam filter actually works.”
“The webhook payload is signed, idempotent, and well-shaped. It reads like code from a competent team, not a CRUD app held together with duct tape.”
“I stopped reaching for Typeform on small marketing sites. splitforms covers 90% of the use case at none of the bloat.”
“I onboarded our whole agency in an afternoon. The MCP integration meant Cursor literally dropped the form straight into our client repos for us.”
“The free plan gave me 500 submissions before I paid a cent, and Pro is five dollars a month. I've spent more on coffee deciding which backend to use.”
“Spam went from forty junk entries a day to zero, with no reCAPTCHA puzzle ruining the form. The honeypot and time-trap just quietly do their job.”
“Point the form action at one endpoint and you're done. No SDK, no client library, no build step. This is how a form backend should feel.”
“Leads land in Slack the second someone submits, and a copy goes to Google Sheets for the sales team. I wired both up in under ten minutes.”
“I run a static Hugo site on a five-dollar VPS. splitforms gave it a real contact form without me standing up a single server.”
Questions
It's debated. NPS is a directional sentiment indicator, not a precise measurement. Used in isolation it's misleading; tracked over time alongside churn and product metrics, it's useful. The form mechanics are simple either way — what you do with the data is the harder question.
Export CSV from the splitforms dashboard. Bucket scores: 9-10 = Promoter, 7-8 = Passive, 0-6 = Detractor. NPS = (% Promoters) − (% Detractors). Excel or Google Sheets handles this in two formulas.
Both work. Email link (one-click into the form) gets higher response rates for transactional NPS (post-purchase). Embedded surveys (logged-in dashboard, app onboarding) get higher response rates for relationship NPS (general satisfaction). The form HTML is the same; the distribution channel changes.
Yes — splitforms ships signed webhooks on paid plans. POST every NPS submission to your data warehouse, BigQuery, Snowflake, or Mixpanel, and join with user metadata downstream.
