Fairing alternatives: what four Shopify survey apps cost at your order volume

We ran a post-purchase survey on our own store for years before building one, so this comparison is written from the merchant's side of the invoice. Every price below comes from the app's own Shopify App Store page, read on September 29, 2026. Where an app is better than ours, we say so.

What each app costs at your volume

The five apps charge in different ways, which is why "which is cheapest" has no single answer. Fairing charges by orders. Customer Luv and Zigpoll charge by responses (one completed survey, however many questions). KNO charges by plan, with unlimited responses. Grapevine has one flat plan. Here's what that works out to each month:

Monthly list prices from each app's Shopify App Store page, September 29, 2026, before annual discounts. Fairing prices by orders; Customer Luv and Zigpoll by responses, so we assumed about half of buyers answer. KNO's $19 plan is one survey with three questions (more questions start at $119); Grapevine is one flat plan. Fairing publishes prices up to 5,000 orders and "custom" from 30,000.

Two things stand out. Fairing's jump from free to $49 happens at 201 orders, so a store that's growing past 200 a month feels it right away. And Zigpoll's response caps (200, then 600) mean a busy thank-you page moves you up tiers quickly — at 3,000 orders you'd be on its $399 plan.

When to stay on Fairing

Fairing is a very good product with 195 reviews averaging 5.0, and for some stores switching is the wrong call:

If none of those describes you, you're mostly paying for the thank-you-page survey itself, and that's the part every app on this list does.

The four alternatives and their trade-offs

1. Customer Luv Surveys — ours

One question at a time on the thank-you and order status pages, with a different question set per product, and separate sets for first-time and returning buyers. Finishers can get a free gift or a unique one-use discount code created in your Shopify. Every answer goes to Klaviyo as an event and a profile property, to GA4, to the customer's Shopify tags and metafields, and can trigger Shopify Flow. You can also build surveys by talking to Claude or ChatGPT.

Price: free for 100 responses a month (one set, three questions); $9 for 2,000 responses and four sets; $29 for 10,000; $49 unlimited with branching logic. 30-day trial on paid plans.

The trade-offs: it's new (launched on the App Store in July 2026), it has far fewer integrations than Fairing, it has no on-site surveys (only checkout pages, plus one-tap answer links you paste into Klaviyo emails or texts), and conditional follow-ups are on the $49 plan.

2. KNO Post Purchase Surveys

A strong research tool: 12 question types, deep conditional logic, audiences, and benchmarks against other brands on its Analyst plan. Every plan has unlimited responses, which makes it predictable at high volume.

Price: $19 (one survey, three questions), $119 (two surveys, 999 questions, benchmarks, two integrations), $299 (four surveys, unlimited audiences). 7-day trial. 4.9 stars from 117 reviews.

The trade-off: the $19 plan is tight. It has no integrations and no audience targeting, so answers stay in KNO rather than reaching Klaviyo. Most stores that want either end up on $119. (KNO and Customer Luv, plan by plan.)

3. Grapevine Post Purchase Survey

The simplest pricing on the list: one plan, $25 a month, unlimited responses and no overage fees. It covers post-purchase, NPS and CSAT surveys, targets by order value, product, country and customer type, and can also ask on-site, by email and on Shopify POS.

Price: $25 a month, 14-day trial. 5.0 stars from 228 reviews.

The trade-off: there's no free plan, so a small store pays $25 from the first month.

4. Zigpoll Customer Surveys

The broadest survey tool on Shopify: post-purchase plus on-site polls, exit-intent and email surveys, with weekly AI summaries and a long integration list (Klaviyo, GA4, Mailchimp, Gorgias and more). 552 reviews at 5.0.

Price: free for 50 responses a month, $39 for 200, $129 for 600, $399 unlimited. About 25% off billed annually.

The trade-off: the response caps are low for a thank-you-page survey, so post-purchase alone can push a growing store up the tiers.

How to switch without losing your data

1. Export first. Download your Fairing responses as a CSV. Your history also stays on the Klaviyo profiles Fairing already synced.
2. Copy your questions word for word. Same question, same answer labels, same order of importance. If "Podcast" was an option before, keep calling it "Podcast" so month-over-month numbers still line up.
3. Match the Klaviyo property names if your flows or segments read them, or update the segments on the day you switch.
4. Run both on a test order. Add the new app's block to the thank-you page, place a test order, and check the answer lands in Klaviyo and Shopify.
5. Then turn Fairing's block off and cancel after your next billing date. Don't leave both surveys live for real customers.

Most stores are done in an afternoon. The first week of answers tells you whether the new app is capturing what the old one did.
