The short answer
Both sides assessedSalesViewer compared with Whois Visiting
Whois Visiting starts lower at $69 a month, adds a 4.5 million company prospecting database and a genuine white-label product for agencies, and calculates your actual rate from your traffic during the trial. SalesViewer costs more, publishes no prospecting database, and instead brings certifications, EU hosting, session video, and mobile apps. Take Whois Visiting for agency resale and list building; take SalesViewer when the compliance file is the deliverable.
Whois Visiting compared with SalesViewer
SalesViewer is the German equivalent at 99 euros a month for 50 company detections, with certified GDPR and CCPA documentation, a published opt-out mechanism, and mobile apps. Whois Visiting starts lower and offers white label and a prospecting database, but publishes far less about its legal posture. This is a straightforward compliance-versus-flexibility trade: SalesViewer if a data protection officer signs the purchase order, Whois Visiting if the sales team does.
Choose SalesViewer if

Choose Whois Visiting if
UK and international B2B companies that want straightforward company-level identification with contact discovery attached, marketing agencies that need a genuinely white-labelled visitor identification product to resell under their own brand, and teams that want unlimited users without a seat tax.

| Setup time | Minutes for the tracking code, with the vendor stating results appear within minutes of installation. Budget additional time to wire consent through your consent management platform properly, which the vendor's own guidance treats as part of the setup rather than an afterthought. | Under five minutes in practice. Sign up, take the tracking code, drop it in the site header, and companies begin appearing. The vendor claims under two minutes for the code itself and tracking begins immediately. |
| Learning curve | Low. Smart categories provide working groupings without configuration, scoring is automatic, and the interface is a filtered company feed with a detail view.

Strengths and limitations
SalesViewer
Strengths
- The strongest documented compliance position in this category: externally audited GDPR certification from 2018 and re-certified in 2020, a separate CCPA certification from 2019, and regular independent audits.
- Cookieless tracking that operates, per the vendor, without IP address references, which is an architectural answer to the category's central legal problem rather than a policy workaround.
- All data in European ISO-certified data centres, a migration completed in 2014 rather than retrofitted under regulatory pressure.
- A published voluntary visitor opt-out that the vendor describes as exceeding legal requirements, in a category where most vendors publish no opt-out mechanism at all.
Limitations
- By far the highest cost per identified company in this category, at roughly two euros at entry and still 84 cents at the top published tier.
- Fifty detections a month on a single website is a very small entry allowance, and the ladder gets expensive fast at 339 and 629 euros.
- Website count is gated by tier, so a company with several brands pays for volume it may not need.
- Company-level only. It never identifies the individual, and unlike US competitors it has no person-level layer to switch on anywhere.
Whois Visiting
Strengths
- Fourteen years of continuous operation with a real customer base of 2,000-plus businesses, which is a stability profile most of this category cannot claim.
- A genuine white-label product rather than a multi-client dashboard, which makes it the strongest agency option among small company-level tools.
- Unlimited users on every plan, so team size never becomes a cost decision.
- The built-in 4.5 million company prospecting database with employee email export means one subscription covers both inbound signal and outbound list building.
Limitations
- The price is calculated from your traffic during the trial, so the published $69 floor is not a quote and you cannot budget in advance.
- No published match rate, methodology, or independent verification, so resolution quality is entirely something you have to establish yourself.
- No person-level identification. The email finder gives you contacts who work at the company, not the human who was on your site.
- Compliance documentation is thin: a GDPR page and a privacy policy, but no published legal basis analysis, data residency statement, or visitor opt-out workflow.

SalesViewer is the most expensive company-level identification per unit in this category, and it is not close. What justifies the price is not the reveal, which is comparable to a dozen cheaper tools, but everything wrapped around it: externally audited GDPR and CCPA certifications rather than assertions, European ISO-certified hosting since 2014, cookieless architecture that does not depend on a mechanism browsers are removing, a stated design that avoids IP address references entirely, a published voluntary opt-out, and consent guidance tied to actual German statute. Add video session recording and native mobile apps, neither of which competitors at any price reliably offer. If your purchase has to pass a data protection officer, that file is the product and two euros per identified company is cheap next to a stalled project. If nobody is asking those questions, you are overpaying by an order of magnitude and Leadberry, Salespanel, Snitcher, or Leadinfo will serve you better.
Whois Visiting
Monthly or annual subscription with the rate calculated from your website traffic volume during the free trial, unlimited users included on every plan, and a 20 percent discount for paying annually.
- MonthlyFrom $69
- AnnualFrom $745.20
- White labelQuoted
Judged on the floor price with unlimited users, Whois Visiting is reasonable value for company-level identification, sitting below Leadinfo and SalesViewer at entry and above Leadberry. The email finder and the 4.5 million company prospecting database add genuine capability that competitors either charge separately for or do not offer, and for an agency the white-label product is worth more than any feature comparison, because it changes what the agency can sell rather than what it can see. The honest problem is that you cannot know your price until the trial ends, and a vendor that scales the rate with traffic is structurally incentivised in the opposite direction from a customer who wants more traffic. Do the trial, get the number in writing, and compare it against Leadinfo, SalesViewer, and Snitcher at your actual volume rather than at the advertised floor.
Editorial verdict on each
SalesViewer
InnovationSalesViewer is the tool you buy when the data protection officer, not the sales director, has the final say. Cookieless tracking that the vendor says never references IP addresses, European ISO-certified hosting since 2014, externally audited GDPR and CCPA certifications, consent guidance tied to actual German statute, and a published voluntary opt-out add up to the only genuinely substantiated compliance story in this category, and video session recording plus native mobile apps are real product advantages on top. The price is the problem: roughly two euros per identified company at entry and still 84 cents at the top tier, which is ten to thirty times what Salespanel, Leadberry, or Snitcher charge for company-level data. Buy it in Germany, the DACH region, or anywhere else a compliance review can kill the project, and treat the premium as the cost of a purchase that gets approved. Anywhere else, it is a lot of money for a company name.
Read the full SalesViewer profileWhois Visiting
Whois Visiting is a solid, unglamorous company-level identification tool with two features that genuinely set it apart from its price peers: a 4.5 million company prospecting database that makes one subscription cover inbound signal and outbound list building, and a real white-label product that lets an agency sell this as its own service. For an agency, that combination makes it the first thing to look at in this price bracket. For a direct buyer, the picture is more mixed. The floor price is competitive and unlimited users are a real saving, but the vendor calculates your actual rate from your own traffic, publishes no match rate, and publishes little compliance detail, which means you are running a fourteen-day trial to discover both what it resolves and what it costs. Do exactly that, get the number in writing, and compare it at your real volume against Leadberry below it and Leadinfo, SalesViewer, and Snitcher above it before you sign anything.
