UXtweak

What Is UXtweak?

A researcher watching heatmaps in one tool, running card sorts in a spreadsheet, and moderating interviews over a video call in a third app loses time stitching insights together instead of acting on them. That fragmentation is the exact problem UXtweak set out to fix when a group of UX researchers from Slovak Technical University and marketers from an advertising agency in Bratislava built it in 2019. Rather than another single-purpose heatmap tool, they wanted one platform that covered the whole research process they were already running for their own clients.

UXtweak j. s. a. is registered in Bratislava, Slovakia, and remains largely self-funded — the company has taken on minimal outside investment and instead grew off its own revenue, reporting roughly €1.08 million in turnover and a return to profit in its 2025 Slovak commercial-register filing. Early clients included Generali and KBC Bank. The platform has since expanded from a session-recording tool into a broader UX research suite. Usability testing, tree testing, card sorting, prototype testing, and live moderated interviews now sit alongside recording and heatmaps in one account.

That positioning matters for how EuropeanStack categorises UXtweak. It competes with pure session-replay tools like Hotjar or Crazy Egg, but its actual scope sits closer to a research operations platform. It's the kind of tool a dedicated UX team reaches for, not just a marketing team checking scroll depth.

The company describes its own mission as democratising professional UX research: making a tool that would previously have required a specialised agency retainer available at a price a mid-size product team can justify. That framing shows up in the product decisions. The free tier is genuinely usable rather than a lead-generation gate. Features like card sorting and tree testing, once the domain of Optimal Workshop or a paid research consultancy, sit inside the same subscription as session recording.

Key Features

Session Recording With Deep Filtering

UXtweak's session recording indexes every user interaction and makes it searchable through more than 40 built-in filters, with the option to define custom ones. Combined with clickmaps, heatmaps, and path analysis, it covers the standard behavioural-analytics use case that tools like Hotjar and Mouseflow are built around, without requiring a separate product.

Usability and Prototype Testing

Beyond passive recording, UXtweak runs structured usability tests on live websites, mobile apps, and prototypes. The Figma integration imports prototypes directly, preserving screens and transitions, so researchers don't have to manually rebuild flows inside the testing tool. A Jira plugin lets teams embed fully interactive prototypes straight into tickets, which shortens the loop between a usability finding and an engineering task.

Information Architecture Tools

Card sorting (open, closed, and hybrid) and tree testing are where UXtweak clearly separates itself from session-recording competitors. Neither Hotjar nor Crazy Egg offers native information-architecture testing at all. For teams redesigning navigation or validating a content taxonomy before launch, this removes the need for a second specialised tool such as Optimal Workshop.

Live Interviews and a Global Panel

UXtweak supports both freeform and structured moderated interviews inside the platform, and its User Panel claims reach across 130 countries for recruiting external participants. This is an add-on rather than a base-plan feature, but it means a research team can go from recruiting to interviewing to synthesis without leaving the tool, which matters when studies run on tight deadlines.

Surveys and Quick-Read Feedback

Beyond the deeper research methods, UXtweak also covers the faster, cheaper feedback formats teams reach for between full studies: first click testing, five-second tests, preference testing, and standalone surveys. None of these are groundbreaking on their own; plenty of standalone tools do one of them well. But having them inside the same account as session recording and card sorting saves real time. A researcher can validate a quick hypothesis on Monday and run a full moderated study on the same participant pool by Friday, without re-recruiting or switching platforms.

Where the Ecosystem Falls Short

UXtweak doesn't publish a public API or webhook documentation, which limits how far teams can automate reporting or push results into a data warehouse. Its outbound integrations are effectively Figma and Jira; there's no confirmed native connector for Slack, Notion, or common analytics stacks. For a platform this feature-rich, that's a real gap versus more developer-friendly competitors, and it's worth checking before committing if your workflow depends on piping research data elsewhere automatically.

Pricing

The Free plan is a genuine trial path rather than a marketing gimmick: one user, 15 responses a month, one active study, and no credit card required. It's enough to run a small pilot study and see whether the interface fits your team's workflow before paying anything.

Business costs €92 per month billed annually, per license, and includes 50 responses per license monthly (upgradable), unlimited tasks per study, and video, PDF, and CSV exports with 12-month data retention. That's competitive against enterprise-oriented tools like UserTesting. But the per-license response cap means active research teams often outgrow the base allowance within a few months and need to buy add-ons. The Custom tier removes those caps entirely, adds SSO, custom branding, and full User Panel access, and includes a dedicated UX expert for onboarding — priced individually per organisation rather than published.

One genuine value point stands out. Live Interviews and User Panel recruitment, features that many competitors bundle only into top-tier enterprise plans, are available as line-item add-ons on the Business plan, not locked behind a Custom-only wall.

EU Compliance & Privacy

UXtweak stores customer data on AWS servers in the Ireland region (eu-west-1), and the company offers a free Data Processing Agreement to every customer rather than reserving it for enterprise accounts. As a Slovak-registered company, UXtweak falls squarely under GDPR and Slovak data-protection oversight, with payment processing routed through Stripe under PCI DSS SAQ A.

For UX research specifically, EU data residency carries extra weight: session recordings and interview transcripts often capture identifiable user behaviour, so where that data physically sits matters for compliance teams reviewing vendor risk. UXtweak's default EU hosting removes one common objection that comes up when evaluating US-headquartered research tools for use with European user bases.

That said, UXtweak doesn't publish a formal ISO 27001 or SOC 2 audit report on its own site. Its compliance posture rests on its EU hosting choice and contractual DPA rather than a third-party certification badge. Procurement teams running a formal vendor-risk questionnaire should ask UXtweak directly for underlying AWS compliance documentation, since AWS itself carries the relevant certifications for the infrastructure layer.

Who It's Best For

Small product teams validating a redesign get the Free plan plus card sorting and tree testing, covering ground that competitors would charge extra for. Dedicated UX research functions inside mid-size companies will likely find the Business plan's mix of recording, testing, and interviews in one login saves more time than the per-license response caps cost. EU-based teams that need data residency guarantees for research participants benefit from UXtweak's Ireland hosting and included DPA, which simplify vendor approval. Anyone whose workflow depends on API access to automate research reporting into a BI tool should flag UXtweak's lack of a public API as a blocker early.

The Verdict

UXtweak earns its place against Hotjar, Mouseflow, and Crazy Egg by refusing to stay a single-purpose replay tool. Card sorting, tree testing, and prototype testing under one roof genuinely change the calculus for research teams that would otherwise juggle three or four subscriptions. The trade-offs are real, though. New users face a learning curve navigating the full feature set, the Business plan's response caps push costs up quickly for active teams, and the absence of a public API limits automation. Teams that value breadth over a narrow analytics focus, and want EU-hosted data by default, will find it a strong, self-funded alternative to the US session-recording incumbents.
