Why visz.ai instead of a US behaviour tool?

Because your visitors' data does not leave the EU: EU-only hosting in Germany, no US jurisdiction, pure data processing with no secondary use for advertising, cookieless-capable, PII masking in the browser, IP anonymisation before storage, and every feature in every plan.

Can US behaviour tools be used in a GDPR-compliant way?

Usually yes, but with effort: opt-in consent before the script loads, a data processing agreement, an updated privacy policy and a safeguard for the US transfer (mostly via the Data Privacy Framework). The review effort is higher than with EU-only processing.

What is the Data Privacy Framework and why is it a risk?

The EU-US Data Privacy Framework makes data transfers to the US legally permissible. It is valid as of July 2026, but its predecessors Safe Harbor and Privacy Shield were struck down in court. If you process EU-only, you do not depend on its survival.

Do I need a cookie banner with visz.ai?

For session replay you need consent under Section 25 of Germany's TDDDG, like with other tools. The snippet itself is cookieless-capable. The difference is the data flow behind it, not the banner.

What does visz.ai do differently?

EU-only hosting instead of a selectable or US region, pure data processing with no advertising use, cookieless-capable, PII masking and IP anonymisation by default, one product instead of separate modules, no random sample of the recordings, and every feature in every plan.

How do I switch to visz.ai?

Create an account, add the tracking snippet, done. Historical data from other tools cannot be imported; the snippets can run in parallel during the transition.

Comparison

See behaviour while the visit is still running

Your visitors leave. They know why, but do you? See what they see.

visz.ai shows you what really happens on your website: recordings of real visits, heatmaps, funnels, frustration signals, surveys and form analytics in one product. On the write path there is no queue and no collection window: an event goes straight into the database, and a recording is playable while the visit is still running.

The second pillar is the place. Hosting is EU-only in Germany (Hetzner, Nuremberg), cookieless-capable, with PII masking in the browser and IP anonymisation before storage. That is EU law and GDPR without a US transfer chain, pure data processing, no secondary use of your data. Every feature is included in every plan.

Most well-known behaviour-analytics tools come from the US and run on US cloud infrastructure. This comparison names no vendor and paints no villain: many US tools are mature and professionally run. The difference is how fast you see something, where your visitors' data lives and which law governs it.

Privacy & EU law

EU hosting and EU law instead of US cloud

The most important difference is not a feature list but where your visitors' data lives and which law governs it. visz.ai processes exclusively in the EU; most well-known behaviour tools come from the US and run on US cloud infrastructure.

The comparison at a glance

Privacy comparison: visz.ai versus typical US behaviour tools. A general, vendor-agnostic assessment.
Criterion	visz.ai	Typical US alternative
Hosting location	EU-only in Germany (Hetzner, Nuremberg).	US cloud infrastructure; an EU region is sometimes selectable, but operations stay US-run.
Applicable law	EU and German law only.	US companies are subject to US law such as the CLOUD Act, regardless of storage location.
Third-country transfer	No transfer of visitor data to third countries.	US transfer is common, usually covered by the Data Privacy Framework, whose future is uncertain.
Use of the data	Pure data processing, no use for own purposes or advertising.	Usage data partly flows into the vendor's own product or advertising purposes.
PII masking	Client-side, before data leaves the browser.	Masking usually available, scope and default settings vary.
IP addresses	Anonymised before storage.	IP anonymisation is not consistently the default.
Cookies	Cookieless-capable, consent-first.	Often set cookies; EU traffic requires opt-in.

EU hosting instead of US cloud.

visz.ai hosts exclusively in Germany (Hetzner, Nuremberg). There is no selectable US region because there is not meant to be one: your visitors' data does not leave the EU.

Many well-known behaviour tools, by contrast, run on US cloud infrastructure. Some offer an EU data region, which is fair and a real advantage over pure US hosting. But the operations, the support and the corporation behind it stay US-run.

Why the company's home matters (CLOUD Act).

A US company is subject to US law even when data physically sits in the EU. The CLOUD Act can allow US authorities to access data a US provider controls, regardless of storage location. That is not a documented incident, it is the structural legal position that belongs in a transfer impact assessment.

US transfers are currently covered mostly by the EU-US Data Privacy Framework. That holds as things stand today but depends on the framework's survival, whose predecessors were struck down in court. visz.ai processes visitor data EU-only and does not have that transfer chain in the first place.

Data minimisation instead of an ad ecosystem.

At some tools, data usage is part of the business model: usage data flows into the vendor's ecosystem, sometimes as far as advertising. visz.ai is a pure data processor, does not use your visitors' data for its own purposes and is not financed by it.

With visz.ai you also need consent for session replay under Section 25 of Germany's TDDDG. The difference is not the banner but the data flow behind it: EU-only, no advertising use, PII masking in the browser, IP anonymisation before storage.

Where established US tools shine: maturity & compliance documentation.

A fair comparison names both sides. On these points, large established vendors are often well set up:

Professional compliance documentation: public data processing agreements with standard contractual clauses and public subprocessor lists.
Selectable EU data regions at several vendors, which is a real advantage over pure US hosting.
Established certifications and audits (such as SOC 2 or ISO 27001) with a long history.
Large legal and security teams that address transfer questions in a structured way.
A long track record that a young product still has to match.

If extensive certification documents and a selectable EU region are enough for you, established US tools are solid. If your visitors' data must not touch the EU or US jurisdiction at all, visz.ai is built for that.

Control & transparency

Data sovereignty, clear roles, no secondary use

Beyond data location, it matters who keeps control of the data and how transparent the terms are. visz.ai is a pure data processor, publishes its subprocessors openly, and includes every feature in every plan.

The comparison at a glance

Control and transparency comparison: visz.ai versus typical US behaviour tools. A general, vendor-agnostic assessment.
Criterion	visz.ai	Typical US alternative
Role in processing	Data processor on your behalf, bound by your instructions.	Partly position themselves as controllers for usage data.
Data processing agreement	The DPA is part of the terms and is concluded at sign-up.	Publicly documented; how it is concluded and what it covers varies by vendor.
Recording scope	No random sample: nothing is filtered out by sampling, recording runs up to your plan's quota.	Recordings are partly collected as a sample only.
Secondary use of data	No use for advertising or own purposes.	Use for product improvement or advertising is sometimes part of the model.
Subprocessors	Public subprocessor list (transparency requirement).	Subprocessor lists usually public, often with US services.
Privacy as architecture	Cookieless-capable, PII masking and IP anonymisation by default.	Privacy features exist, but often optional to configure.
Scope in one product	Replay, heatmaps, funnels, forms, surveys and frustration signals in one product, included in every plan.	Comparable scope often spread across several product lines or modules.

Data processor, not data reseller.

visz.ai is your data processor: your visitors' data belongs to you, is processed on your instructions and is not repurposed for its own ends. The data processing agreement is concluded at sign-up as part of the terms.

Some US tools, by contrast, position themselves as controllers for the usage data they collect and reserve the right to use it for their own product or advertising purposes. That is a structural difference in the business model, not just a setting.

All features instead of a module kit.

At visz.ai every plan contains every feature: session replay, heatmaps, funnels, form analytics, surveys and frustration signals. There are no add-on modules and no feature that has to be unlocked first.

At many alternatives the full feature set is spread across several product lines or add-on modules, and recordings are partly collected as a sample only instead of being stored in full.

Transparency as a principle.

At visz.ai, privacy is architecture, not an add-on: cookieless-capable, client-side PII masking and IP anonymisation are active by default, and the subprocessors are listed publicly.

At many tools, privacy features do exist but have to be configured correctly before they take effect. The default decides, and defaults are easy to forget.

Where established US tools shine: feature breadth & scale.

The other side belongs here too. Large vendors are often ahead on these points:

AI analysis: automatic session summaries and pattern detection. visz.ai deliberately has no AI layer.
Deep integrations into common marketing and product stacks.
Mobile SDKs and analytics for native apps.
Very high raw data volumes at some vendors.
Maturity, scale and a long track record over many years.

If you need maximum feature breadth, AI analysis and deep integrations, established tools are strong. If you want a focused behaviour-analytics tool without separate modules that treats privacy as architecture, visz.ai is built for that.
