Grapevine vs KnoCommerce: Shopify Post-Purchase Survey App Comparison

Grapevine and KnoCommerce (KNO) are both Shopify apps for post-purchase and attribution surveys. Both work on the Shopify thank-you and order status pages, both give you unlimited responses, and both send answers to Klaviyo and Shopify Flow.

The difference is what you get for the money. Grapevine is $25 a month for unlimited surveys, every integration and NPS included. KNO starts at $19 a month for one survey with three questions, then $119 or $299 a month for more surveys and integrations, with NPS as a paid add-on on every plan.

KNO goes deeper on attribution analysis. Grapevine gives you more for less. This page lays out both so you can pick what matters to you.

Pricing: Grapevine vs KnoCommerce

This is the biggest difference between the two apps.

Grapevine Surveys

  • $25/month
  • Unlimited surveys
  • Unlimited responses
  • NPS included
  • Every feature and integration included, no cap on how many integrations you use
  • MCP and AI access included
  • No annual contract required
  • Price stays the same as your store grows

KnoCommerce (KNO)

  • Starter, $19/month: 1 survey, 3 questions per survey
  • Analyst, $119/month: 2 surveys, 2 active integrations, benchmarks
  • Pro, $299/month: 4 surveys, 4 active integrations, survey links
  • Unlimited responses on every plan
  • NPS is a paid add-on on every plan
  • 7-day free trial

What this means in practice. KNO's Starter plan is $6 cheaper than Grapevine, but you get one survey with three questions. Want a second survey, or your answers flowing into Klaviyo? That's the $119 Analyst plan. Want NPS too? That's extra on top. With Grapevine, all of it is in the $25 plan.

To be fair to KNO, it doesn't charge by responses or orders, so a busy month won't push you up a plan. What pushes you up is wanting more surveys, more integrations or more targeting.

Key differences between Grapevine and KnoCommerce

What the price gets you. The big one. Grapevine is $25 a month with no limits on surveys, questions or integrations, and NPS included. KNO's $19 plan covers one survey with three questions. Most stores running attribution plus NPS, with answers going to Klaviyo, end up on KNO's $119 plan plus the NPS add-on.

Depth of analysis. KNO is built for attribution analysis with real depth: filtering across 60+ Shopify attributes, modelled attribution for customers who don't answer, and benchmarks against other brands. If you have someone in-house whose job is to work that data, KNO earns its price.

Your data and your AI. Grapevine's MCP connector is part of the $25 plan, so you can ask Claude or ChatGPT questions about your survey results in plain language, like which channel drove the most revenue last month. See it in action: Attribution Anomaly Detection with Claude.

Built for Shopify. Grapevine carries Shopify's Built for Shopify badge, its accreditation for apps that meet the highest standards for performance, design and integration. KNO doesn't currently have it.

Simplicity. Grapevine is one plan with everything in it. No deciding which tier you need, no counting surveys, no choosing which two integrations to switch on.

Who should choose which

KnoCommerce may be the better choice if:

  • You need conditional logic, so each customer gets a different follow-up based on their last answer.
  • You want to filter and segment answers across 60+ Shopify attributes.
  • You want modelled attribution and benchmarks against other brands built in.
  • You have someone on the team whose job is to work the attribution data.

Grapevine is the better choice if:

  • You want more than one survey without paying $119 a month.
  • You want NPS included, not as an add-on.
  • You want every integration switched on, not two or four.
  • You want Shopify POS surveys. KNO doesn't offer them.
  • You want an app with the Built for Shopify badge.
  • You want one plan with everything in it.

Grapevine is built by a small independent team of four with over a decade of experience building Shopify apps. The flat price is a deliberate choice. Read more about why we price this way.

Grapevine vs KnoCommerce: FAQs

For most stores, yes. KNO's Starter plan is $19 a month, but it covers one survey with three questions, and NPS costs extra. More surveys and integrations mean the $119 Analyst or $299 Pro plan. Grapevine is $25 a month with unlimited surveys, every integration and NPS included.

No, and we'd rather say so. KNO has conditional logic, filtering across 60+ Shopify attributes, modelled attribution, benchmarks and a REST API, which Grapevine doesn't.

Grapevine covers the core: post-purchase, attribution, NPS, CSAT, email, on-site, exit-intent and POS surveys, plus Klaviyo, Shopify Flow, GA4, Google Sheets and MCP, all for $25 a month.
