Customer Research Tools for CRO: Surveys, User Testing and Replay

The customer research tools that matter for CRO fall into four groups: message testing (Wynter), user testing (UserTesting, Maze, Lyssna), on-site and post-purchase surveys (Hotjar Surveys, KnoCommerce, Fairing, Zigpoll) and session replay (Microsoft Clarity, FullStory, Mouseflow).

Most stores should start with free Clarity plus one cheap post-purchase survey, and pay for a panel tool only when they need answers from people who are not already customers.

Each tool answers a different "why" question. Below we match questions to tools, cover price and downsides, and show real tests from our database that started with research.

We have not used these tools ourselves. This roundup is based on each vendor's pricing pages and docs, checked in November 2026. If you sign up for Heatmap.com or Lucky Orange through our links we may earn a commission.

We earn nothing from the other tools listed.

Which research question needs which tool

Start with the question, not the tool. Every tool here is good at one kind of "why" and weak at the rest.

  • "Do visitors understand what we sell?" Message testing or a five-second test (Wynter, Lyssna).
  • "Where do people get stuck?" Session replay and heatmaps (Clarity, FullStory, Mouseflow), then user tests to hear why.
  • "What almost stopped buyers from buying?" A post-purchase survey (KnoCommerce, Fairing, Zigpoll).
  • "Why are visitors leaving this page?" An on-page exit or intent survey (Hotjar Surveys, Zigpoll).
  • "What words do customers use?" Review mining and support tickets, which cost nothing.

Our guide to customer research for CRO covers the methods in more depth. This page covers the software.

Message testing: Wynter

Wynter shows your homepage, landing page or pricing page to people who match your target buyer, and they comment line by line on what is clear, what is confusing and what they don't believe.

Its site lists message tests, preference tests, surveys, pricing page tests and 1:1 interviews, drawn from a panel of 86,000+ B2B professionals verified by work email.

As of November 2026, the Wynter pricing page lists Pro at $20,000/year, Elite at $40,000/year and Wynter Black at $100,000/year.

There is also pay-as-you-go, which Wynter says costs about 50% more per test than a subscription. Results arrive in under 48 hours.

Not for: ecommerce stores and consumer apps. The panel is B2B only, so a skincare brand can't reach its buyers here.

The price also puts it out of reach for small teams.

See our Wynter review and the wider list of message testing tools for cheaper options.

User testing: UserTesting, Maze, Lyssna

User testing means watching real people try to complete a task on your site while they talk through it.

It is the fastest way to hear the reason behind a drop-off you saw in analytics.

UserTesting

UserTesting is the enterprise option. Its plans page lists Advanced, Ultimate and Ultimate+ tiers but publishes no prices: you contact sales, and the company says price depends on users, test types and features.

That makes it hard to justify for a store that only needs a few sessions a quarter.

Maze

Maze is built for product and design teams who test prototypes, run surveys and do unmoderated usability tests.

It has a free plan, but the Maze pricing page did not show paid prices when we checked, and Maze's own help center says it sometimes trials revised pricing, so the plans you see may differ.

It is a better fit for testing a design before launch than for diagnosing a live checkout.

Lyssna

Lyssna has the most open pricing of the three.

As of November 2026, the Lyssna pricing page lists a free plan (3 seats, 15 self-recruited responses), Growth at $166/month billed yearly and a custom Enterprise plan.

Participants from its 690,000+ person panel are paid for separately on every plan.

Lyssna's quick tests (five-second, first-click, preference) suit CRO well: you can check whether a new hero communicates the offer before you spend traffic on an A/B test.

Our user testing tools roundup compares more options.

On-site and post-purchase surveys: Hotjar Surveys, KnoCommerce, Fairing, Zigpoll

Surveys are the highest-value research for most ecommerce stores, because buyers tell you directly what nearly stopped them.

Our database has several winning tests that started this way.

Kasper Dolk added benefit bullets to a product page hero that answered survey objections, worth +$763,679.14 profit/year.

Oliver Kenyon placed three survey-based reassurance lines above a collection page grid, worth $44,890/month.

In both cases the copy came from customers, not from a brainstorm.

Hotjar Surveys

Hotjar is now part of Contentsquare. Contentsquare says new Hotjar accounts can no longer be created, and new users sign up for Contentsquare's free plan instead, which includes surveys (100 responses a month), heatmaps and session replay.

Existing Hotjar users can keep using it, but plan for the product to keep changing.

KnoCommerce

KnoCommerce is a Shopify post-purchase survey app. As of November 2026, the KnoCommerce pricing page lists Starter at $19/month (1 live survey, 3 questions, no integrations), Analyst at $119/month and Pro at $299/month, with a 7-day trial.

The Starter cap of 3 questions is tight if you want both attribution and objection questions.

Fairing

Fairing is known for "how did you hear about us" attribution surveys.

Its pricing page lists a free plan for up to 200 transactions a month, Core at $49/month for 201-500 transactions and custom Enterprise pricing at 30,000+, as of November 2026. It leans toward marketing attribution more than CRO, though you can add your own questions.

Zigpoll

Zigpoll prices by responses. As of November 2026, the Zigpoll pricing page lists a free Lite plan with 50 responses a month, Standard at $39/month for 200 responses, and tiers up to Premier at $399/month for unlimited responses ($29 to $299 billed annually, 25% off). All plans include unlimited surveys.

For a side-by-side of these apps see post-purchase survey apps, and for what to ask, see our page on post-purchase surveys.

Session replay and heatmaps: Microsoft Clarity, FullStory, Mouseflow

Replay and heatmaps show what people do, not why.

They are best for finding where to look, then pairing that with a survey or user test to explain it.

Dave Diederen changed above-the-fold USPs to the points heatmaps showed buyers engaging with and got +7.28% revenue per visitor.

In a separate test, Dave Diederen added a countdown timer where heatmaps showed shoppers were focused, for +20.65% revenue per visitor.

Microsoft Clarity

Clarity is free. Microsoft's FAQ says it is "a free service forever" with no traffic limits.

The main downside is retention: recordings are kept for 30 days, apart from favorites and a random sample kept up to 9 months.

Heatmaps are capped at 100,000 page views each. See our Microsoft Clarity review.

FullStory

FullStory is product analytics plus replay, aimed at SaaS and larger sites.

Its pricing page hides paid prices behind a demo request, but the free plan covers 30,000 sessions a month, 12 months of analytics retention and up to 10 users.

It is more than most small stores need.

Mouseflow

As of November 2026, the Mouseflow pricing page lists a free plan with 500 sessions a month, Essential at $25/month for 5,000 sessions, Advanced at $109/month for 25,000 and Premium at $319/month for 100,000. Retention grows with the plan, from 1 month on Free to 12 months on Premium.

If you want revenue tied to clicks, Heatmap.com starts at $199/month for stores up to $10M revenue, per its pricing page.

Lucky Orange starts at $32/month billed yearly for 3,500 sessions and includes surveys on every plan, per its pricing page.

Both are covered in our session replay tools and heatmap tools roundups.

Voice of customer and review mining

The cheapest voice of customer tool is the data you already have.

Product reviews, support tickets, live chat logs, return reasons and sales call notes all contain the exact words customers use for their problems and doubts.

A simple process works: export a few hundred reviews (yours and a competitor's), tag each one by theme (price, fit, trust, shipping, results), and count.

The top two or three themes become your test ideas, and the customers' own phrases become your copy.

Dedicated voice of customer software adds dashboards and AI tagging, but for most stores a spreadsheet does the job.

Pay for software when the volume of feedback outgrows manual tagging.

Free stack vs paid stack

Free stack: Microsoft Clarity for replay and heatmaps, a free post-purchase survey tier (Fairing up to 200 transactions a month or Zigpoll at 50 responses), Contentsquare's free plan for on-page surveys, and review mining in a spreadsheet.

This covers most of what a store under a few hundred orders a day needs.

Paid stack: add a paid survey tier once free limits run out, Lyssna or a similar tool for quick tests on new designs, and FullStory or Mouseflow if you need longer retention and funnels.

B2B SaaS teams with budget can add Wynter for message testing with real buyers.

The common mistake is buying several overlapping tools and reading none of the output.

One survey you read every week beats four dashboards nobody opens.

More options are in our website survey tools roundup.

From research to a test hypothesis

Research only pays off when it becomes a test.

Turn each finding into a hypothesis: what you saw, what you will change, and what you expect to happen.

For example: "Post-purchase surveys show buyers worried the product would not work for them.

Adding three proof-based benefit bullets to the hero will raise conversion rate."

That is close to the Kasper Dolk test above.

Our guide to writing an A/B test hypothesis walks through the format.

Then run the A/B test. Research tells you what to try, but only the test tells you whether it worked.

Some research-led ideas lose, and that is still useful.

Questions

What are customer research tools?

Customer research tools help you learn why visitors do or don't buy.

For CRO they fall into message testing (Wynter), user testing (UserTesting, Maze, Lyssna), surveys (Hotjar Surveys, KnoCommerce, Fairing, Zigpoll) and session replay (Microsoft Clarity, FullStory, Mouseflow).

What is the best free customer research software?

Microsoft Clarity is free with no traffic limits for session replay and heatmaps.

For surveys, Fairing is free up to 200 transactions a month, Zigpoll's free plan includes 50 responses a month, and Contentsquare's free plan (which replaced new Hotjar signups) includes 100 survey responses a month, as of November 2026.

What are voice of customer tools?

Voice of customer tools collect customers' own words about their needs and doubts: on-site and post-purchase surveys, interviews, user tests and review analysis.

Reviews, support tickets and chat logs you already have are a free starting point.

What is conversion research?

Conversion research is the work of finding out why visitors don't convert, using analytics, session replay, surveys and user tests.

Its output is a list of evidence-backed hypotheses to A/B test.

Is Wynter good for ecommerce?

Usually not. Wynter's panel is made up of B2B professionals verified by work email, so it suits B2B SaaS messaging.

Ecommerce stores get more from post-purchase surveys and user testing tools like Lyssna.
