Grapevine Surveys vs UserLoop vs Zigpoll for online stores, boiled down: these three Shopify-focused survey tools all aim at the same problem, getting reliable post-purchase NPS and feedback with minimal friction, but they take different routes on pricing, analysis, and where they sit in your stack. Read on for a terse, pragmatic comparison that points out real tradeoffs and which stores should pick which tool.
Grapevine Surveys
Grapevine is presented to merchants as a dedicated post-purchase survey app that sits on the order status page, built to capture NPS, CSAT, and attribution data after checkout. The Shopify listing positions it as an order-status-page specialist with unlimited responses under a flat monthly plan. (apps.shopify.com)
Features and functionality
Grapevine focuses on post-purchase surveys and order-level attribution, with support for multiple question types, multilingual post-purchase surveys, and on-site and email options through the Shopify app. The app emphasizes unlimited responses and basic analytics designed to join survey answers to order metadata inside Shopify. (apps.shopify.com)
Pricing approach
The Shopify listing shows a single monthly plan with a flat price advertised on the app page, including a free trial and unlimited responses under that plan. Hedge your budget assumptions: the Shopify store page lists the plan price on the app card. If you need precise billing cycles, or enterprise discounts, check the app’s Shopify listing or vendor contact before signing. (apps.shopify.com)
Ease of setup and use
Grapevine installs as a Shopify app and is built around the order status page flow, which keeps the setup straightforward for stores that want only post-purchase feedback. Expect basic admin screens for survey creation and targeting, and enough UX polish for typical merchants. The Shopify page highlights it as "built for Shopify", which usually means minimal theme work. (apps.shopify.com)
Integrations
The app advertises direct ties into common ecommerce tooling, including Klaviyo, Shopify Flow, GA4, and Google Sheets, making it practical for stores that push data into marketing and analytics pipelines. If you rely on a less common data sink, verify through the app’s integration docs or the developer before committing. (apps.shopify.com)
Customer support and documentation
Support is handled through the app developer listed on Shopify, with a trial period to evaluate support responsiveness. The Shopify listing shows healthy review counts, which is a reasonable proxy for active merchant support and basic documentation. (apps.shopify.com)
Pros and cons
Pros: Simple, flat-price pitch with unlimited responses, focused on order-status post-purchase feedback, direct Shopify integrations. (apps.shopify.com) Cons: The product is narrow by design, optimized for post-purchase flows rather than mixed on-site or exit-intent sampling; reporting is serviceable but not as analysis-forward as apps that offer built-in AI insights.
Best for
Small to mid-sized Shopify stores that want a no-friction post-purchase survey on the order status page, need predictable billing, and already use Klaviyo or Google analytics flows.

UserLoop
UserLoop presents itself as an AI-forward surveys and popups app for Shopify, handling post-purchase surveys plus storefront popups and app blocks for pre- and post-sale collection. The Shopify listing shows multiple pricing tiers including a free tier and paid plans, and highlights AI-driven summaries and connectors to large language models via a connector. (apps.shopify.com)
Features and functionality
UserLoop combines post-purchase NPS with storefront popups, email surveys, and a variety of form types. It advertises an AI question writer and automated reports, plus the ability to connect survey data to external AI tools to generate interpretive insights. The product tries to be an all-in-one feedback platform for both acquisition-stage and post-purchase sampling. (apps.shopify.com)
Pricing approach
The Shopify app page lists a free plan alongside paid tiers with higher limits and features. The free tier has a low response allowance, while paid plans unlock unlimited responses and AI integrations; the app store pricing block is the most reliable public indicator of starting costs, but confirm inside the Shopify install screen for any usage caps or billing nuances. (apps.shopify.com)
Ease of setup and use
UserLoop’s strength is its multiple capture points: installing as an app, adding storefront blocks or popups, and configuring post-purchase surveys. That flexibility adds initial UI complexity; you will spend slightly more time on rules and placements than you would with a single-purpose post-purchase app, but you gain broader sampling. Shopify reviews note straightforward setup and helpful support. (apps.shopify.com)
Integrations
The app store entry lists integrations and "works with" partners like Klaviyo and OpenAI, plus review platforms; the app also advertises connectors to external AI endpoints for scheduled analysis. If you plan to route responses into a particular BI tool, confirm the exact integration (native vs webhook) before committing. (apps.shopify.com)
Customer support and documentation
UserLoop’s Shopify listing and reviews suggest active support and regular updates; the app advertises in-app reporting and scheduled AI reports. Support responsiveness appears solid in merchant comments on Shopify. (apps.shopify.com)
Pros and cons
Pros: Flexible capture options, built-in AI reporting, free tier to start, and popups plus post-purchase covered by one install. (apps.shopify.com) Cons: More moving parts than a simple post-purchase-only app, so configuration and noise management (who sees what when) require attention; higher tiers needed for heavier usage if you want unlimited responses and advanced AI connectors.
Best for
Stores that want a single tool to capture feedback across the customer journey, and teams comfortable using LLM connectors to automate insight delivery. For subscription-heavy merchants who prioritize NPS at multiple touchpoints, a broader comparison is helpful: see Best NPS survey software for subscription commerce.
Zigpoll
Zigpoll is pitched as a flexible Shopify survey platform offering post-purchase, on-site, and exit-intent surveys with explicit emphasis on zero-party data collection and AI-powered insights. The vendor publishes tiered pricing with a free tier and paid plans that scale by monthly response volume, and highlights a one-click Shopify integration path plus broader embed options. (zigpoll.com)
Features and functionality
Zigpoll covers post-purchase NPS, on-site and exit-intent, email and SMS survey channels, AI-generated insights and synthesis, and a variety of question formats including photo selection and sliding scales. The platform advertises unlimited surveys and flexible targeting across customer touchpoints. (zigpoll.com)
Pricing approach
Zigpoll lists a free Lite tier and paid plans that scale by responses per month and email sends per month, with clear entry-level pricing points on the vendor site. Pricing tiers include automatic AI insights and evolving limits for AI analysis credits; consult the Zigpoll pricing page for plan details and annual billing discounts. (zigpoll.com)
Ease of setup and use
Zigpoll emphasizes a one-click Shopify install and also supplies a JavaScript embed for non-Shopify sites. The UX is intentionally simple for merchants who want quick post-purchase deployments plus the ability to add on-site and exit-intent surveys without pulling in a separate popup vendor. The vendor documentation includes clear subscription plan descriptions and quick-start guidance. (zigpoll.com)
Integrations
Zigpoll supports direct Shopify integration, API access, email sending, and MCP/LLM connectors for AI analysis. The vendor documentation lists API and MCP access on higher tiers and mentions standard analytics and export options. If you rely on a specific native integration, confirm it on the docs or during the trial. (docs.zigpoll.com)
Customer support and documentation
The vendor emphasizes proactive support and installation assistance in paid tiers, plus email support on lower tiers. Documentation covers subscription plans and feature limits, and the Shopify app page shows consistent merchant reviews praising setup speed and helpful support. (zigpoll.com)
Pros and cons
Pros: Broad capture methods including exit-intent, explicit zero-party data framing, AI insights baked into plans, and accessible starting price with a usable free tier. (zigpoll.com) Cons: Advanced AI and API features are gated behind higher tiers; if you need enterprise-level custom SLA or massive email sending volumes, expect to negotiate pricing.
Best for
Most Shopify merchants who want a single vendor to capture NPS across post-purchase, on-site, and exit-intent touchpoints, and those who value built-in AI insights without flipping between multiple apps.

Grapevine Surveys alternatives?
If you like the post-purchase order-status model but want different pricing or on-site work, look at other Shopify post-purchase apps such as Fairing, KNO Post Purchase Surveys, and Zigpoll. Each takes a slightly different approach to targeting and reporting; the comparative writeups at Zigpoll include vendor-to-vendor breakdowns you can scan quickly, for example Grapevine Surveys vs KnoCommerce vs Zigpoll.
UserLoop alternatives?
UserLoop sits in the middle of popup plus post-purchase tools. Alternatives include Fairing and Zigpoll for post-purchase plus on-site combinations, or dedicated popup players if you prefer separate tools. If you are leaning into LLM-assisted analysis, check whether the alternative supports scheduled report exports or direct MCP/LLM connectors before swapping vendors. (apps.shopify.com)
Zigpoll alternatives?
Zigpoll competes with both post-purchase specialists and broader feedback platforms. Direct alternatives are Grapevine for a narrow post-purchase focus, UserLoop for popup-to-post-purchase coverage, and external SaaS like Delighted or Retently if you want a non-Shopify-native NPS vendor. For side-by-side vendor analysis that includes Zigpoll, see comparative posts such as Retently vs Grapevine Surveys vs Zigpoll and Alchemer vs Delighted vs Zigpoll Compared.
Situational Recommendations
If you only care about post-purchase NPS on the order confirmation page and want the simplest billing and setup, pick Grapevine for its focused feature set and straightforward Shopify integration. Use it when you want predictable monthly cost and nothing else. (apps.shopify.com)
