Tack vs Useberry: a Useberry alternative without the yearly plan
Useberry is a broad research tool with yearly plans. Tack does fewer things, for people who build in code and test in bursts. Here is where each one fits, and what a year costs.
The Tack team··7 min read
Short answer
Useberry is a remote UX research platform. It tests Figma, ProtoPie and Sketch prototypes and live websites, and adds first click, five-second, preference and A/B tests, card sorting, tree testing, live interviews, recordings and a participant pool. As of November 2026, its pricing page lists a Free plan (10 responses a month), Growth at €83 a month and Business at €659 a month, both billed yearly.
Tack is narrower on purpose. It’s for people who make prototypes in code, with Lovable, v0, Bolt, Cursor or Claude Code, and want to know by tomorrow if the thing works. One <script> tag runs tests on the prototype and short surveys for real visitors on production. Respondents use the real page in their own browser, so one test covers phones and desktops alike. You pay per test, with no yearly plan.
If your team tests Figma designs every week and needs recordings, interviews and a panel, Useberry gives you more for the money. If you test a few times a month, around releases, read on.
What Useberry does well in 2026
Useberry covers a lot of the research toolkit in one place, and a fair comparison should start there:
- Prototype tests for Figma, ProtoPie and Sketch, with more integrations listed as “and more”. (Useberry)
- Live website tests, either through a proxy link for quick checks or with a snippet in your code for deeper interactions. (Useberry)
- Many study types: first click, five-second and preference tests, single tasks, surveys, A/B tests, card sorting and tree testing.
- Recordings and interviews: face, voice and screen, highlight reels, and live interviews inside Useberry.
- A participant pool, or your own people through a share link.
For a design team that runs studies every week, often before a line of code exists, that range is the reason to pick it.
Where Tack is different
1. Built for prototypes made in code
AI tools hand you a running app, not a design file. Tack starts from that URL. Paste one <script> tag into the page and open it once; the install verifies itself. There is no proxy in between, so logins, client-side routing and your own scripts behave exactly as they do for real users.
<script src="https://trytack.io/r/v1.js" data-site="pk_…" async></script>Task success is checked automatically by URL (exact, prefix or regex), by a click on a CSS selector, or by a custom event: window.tack.track('signup_done'). The panel sits inside your page in Shadow DOM and turns into a bottom sheet on phones.
2. The real page at the respondent’s own screen size
In Useberry, the prototype or site opens inside Useberry’s own frame, with a viewport you choose for the study. The page doesn’t adapt to the respondent’s screen, so a study is set up for desktop or for mobile, and covering both means two studies. Useberry users describe mobile prototypes cut off on phones and shrunk to a tiny size on desktop (Useberry feedback board), and Infinum’s design handbook warns that a prototype in Useberry “is not that responsive” and asks you to preview the study on different screen sizes (Infinum handbook).
Tack doesn’t put your page in a frame. The respondent opens the real prototype in their own browser tab, at full size, and your responsive layout does what it always does. One test link works on a phone, a tablet and a desktop, and the results can be filtered by device, so you see straight away whether people on phones struggle where people on laptops don’t.
3. Feedback from real visitors, not only invited testers
Useberry’s pages describe participants who come through a share link or its participant pool. Tack’s snippet also runs Pins on production: 1–3 question surveys for the people already using your site, shown at the right moment.
- Triggers: URL pattern, time on page, scroll depth, exit intent, custom event, Nth visit, device.
- Sampling by % of visitors, a cooldown of X days per visitor, and never more than one Pin per visit.
- A Pin can end with an invite into a Test of the next version.
4. Pay per test, not per year
Small teams rarely test evenly. You test three times in the week before a launch, then not for a month. Useberry’s paid plans are billed yearly: Growth comes to €996 a year for 300 responses a month and one seat. Tack has no plan to commit to. One Test or one Pin costs one credit, and a credit is €8, less in bigger packs. No seats, no subscription, no minimum. Credits don’t expire. A new account comes with 1 credit to try it. See the price list.
€110a yearTack prices come from our live price list, VAT included, with pack discounts. Useberry figures come from its pricing page and public trackers, in its own currency and without tax. Useberry counts responses, so we assume about 10 respondents per test.
The honest flip side: if you test every week with larger groups, a flat Growth plan can come out cheaper than credits. Tack is built for the team that tests when there is something new to test.
5. Standard metrics, read honestly
Templates use validated questions with locked wording and scales: SEQ after each task, UX-Lite, CES, CSAT, NPS and the product-market fit question. Results show reference bands where they exist and warn you when a sample under 30 is too small to trust.
6. Czech and English out of the box
The respondent interface comes in English and Czech, and templates carry both versions of the standard questions. In Useberry you set up custom languages for the texts participants see yourself.
7. Private by default, hosted in the EU
- Data and hosting in the EU.
- Nothing is collected before the respondent consents. If they decline, nothing loads.
- Pins use no cookies and no fingerprinting, only an anonymous ID for frequency caps.
- No IP addresses in results, and input field contents are never recorded.

Which one should you pick?
Choose Useberry if:
- Your prototypes live in Figma, ProtoPie or Sketch.
- You need first click, five-second, preference, card sorting or tree tests.
- You want recordings with face and voice, or live interviews.
- You recruit testers from a participant pool.
- You test every week, so a yearly plan pays for itself.
Choose Tack if:
- You build prototypes in code or with AI tools and test them as they are.
- You want to ask real visitors on production, not only invited testers.
- You test in bursts around releases and want to pay per test.
- You want one test to cover respondents on phones and desktops.
- Your respondents speak Czech, or you care where their data lives.
Plenty of teams will use both: Useberry while the design is still in Figma, Tack once it runs in a browser.
FAQ
What is the best Useberry alternative for testing AI-built prototypes?
If your prototype is a live URL from Lovable, v0, Bolt, Cursor or Claude Code, Tack is built for that: one script tag, automatic task success checks and results by the next day, paid per test. Useberry can test live sites too, and is stronger when designs are still in Figma, ProtoPie or Sketch.
Is Useberry free?
Useberry has a Free plan with 10 responses a month, 1 project and 1 seat. Paid plans start with Growth at €83 a month billed yearly (as of November 2026).
How much does Useberry cost a year?
Growth is €83 a month billed yearly, so about €996 a year for 300 responses a month. Business is €659 a month billed yearly. Enterprise is priced by quote (as of November 2026).
Can I test mobile and desktop in one test?
In Tack, yes. The prototype runs in the respondent’s own browser at their screen size, the Tack panel becomes a bottom sheet on phones, and results can be filtered by desktop, tablet and mobile. Useberry shows the page in its own frame with a viewport set per study.
Can Tack test Figma prototypes?
No. Tack tests anything that runs in a browser. If your design only exists in Figma, ProtoPie or Sketch, Useberry is a better fit.
Can Tack ask visitors on my live site?
Yes. Pins are 1–3 question surveys on production with triggers such as time on page, scroll depth or exit intent, sampling and cooldowns. A Pin can invite the visitor into a Test.
Does Tack record video?
No. Tack records clicks, scroll depth, paths and answers, not video or audio, and never the contents of input fields.
How much does Tack cost?
Signing up is free. One Test or one Pin costs one credit, and a credit is €8, less in bigger packs. No seats, no subscription, no minimum. Credits don’t expire. A new account comes with 1 credit to try it.
