What these tools do

Website visitor identification tools match anonymous traffic to real companies, and sometimes the people inside them, using reverse-IP and B2B data. But they vary hugely: from simple company lists to full pipeline engines, and from free plans to six-figure enterprise contracts. Typical identification rates run 20 to 40% of B2B traffic, depending on your market.

How we ranked

What Actually Turns a Visit Into Pipeline.

We weighed each tool on what actually turns a visit into pipeline: identification rate and coverage (especially UK and EU traffic), whether verified decision-maker contacts are included or metered, whether it acts on the data with outreach and chat or just shows you a list, pricing transparency and contract flexibility, GDPR posture, and how much setup and management falls on you.

Identification Rate and Coverage, Especially for UK and EU traffic, not just the US.

Verified Decision-Maker Contacts, Included in the price, or metered and charged extra.

Acts on the Data, Outreach and chat built in, or just a list of companies.

Pricing Transparency, Public pricing and contract flexibility, or quote-only and locked in.

GDPR Posture, Built for EU and UK privacy, or US-centric and person-level.

Setup and Management, How much falls on you versus done for you.

The 10 best

The Ten Best Visitor ID Tools in 2026.

Best for, pricing and the catch, for each one.

  1. 01

    ContaktlyOur Pick

    Best all-in-one for turning visitors into booked meetings.

    Contaktly identifies the companies visiting your site, finds the decision-makers with verified emails, and books the meeting for you through automated outreach and a 24/7 inbound chat agent. Unlike most tools here, identification, verified contacts, email and WhatsApp outreach, and the chatbot are all included in one flat monthly price, with no per-contact credits and no annual contract. It is built and managed by an outbound agency, so deliverability and copy are handled for you.

    Best for
    B2B teams who want the whole journey, from anonymous visit to booked meeting, in one place.
    Pricing
    From $110/mo, monthly, cancel anytime. Everything included. Backed by a 30-day guarantee: if it does not identify your visitors, you do not pay.

    Why it tops the list: Most tools stop at a list of companies. Contaktly acts on it, and does not charge extra for the parts that generate pipeline.

  2. 02

    Leadinfo

    The best-known European identifier.

    A polished, well-established European tool with strong Benelux coverage and many integrations. Identification and contact data are solid, but the parts that create pipeline, its chatbot (Leadbot) and outreach (Autopilot), are paid add-ons on top of the base plan.

    Best for
    European teams that already have their own outreach stack.
    Pricing
    Entry plan from ~$76/mo, with little in it. A plan comparable to Contaktly's runs to several hundred dollars a month, and chat and outreach cost extra.

    Watch-out: The entry price looks low until you add the modules you actually need.

  3. 03

    Leadfeeder

    Familiar name, back from Dealfront.

    Leadfeeder (which rebranded back from Dealfront in 2026) is widely used, with a free-forever tier and public pricing. It identifies companies well, but verified decision-maker contacts are locked to its higher tiers, and it has no built-in chat or outreach, you export to your own tools.

    Best for
    Teams wanting a free way to see which companies visit before investing.
    Pricing
    Free plan; paid from ~$87/mo. Verified contacts from around $406/mo.

    Watch-out: You get the companies cheaply, but the people and the outreach cost far more.

  4. 04

    Lead Forensics

    The enterprise incumbent.

    One of the oldest and largest identifiers, with a big IP database and contact data. Powerful, but pricing is quote-only, contracts are annual, and deals commonly run into five figures a year. Expect a sales demo before you see a price.

    Best for
    Larger companies with the budget and a preference for a big-brand vendor.
    Pricing
    Quote only, annual contract. Reported median about $17,500 a year.

    Watch-out: No monthly option, no self-serve, and a long sales process.

    Lead Forensics pricing explained

  5. 05

    Albacross

    Identification plus outreach, credit-metered.

    A capable Scandinavian tool that, unlike most, includes automated email and LinkedIn sequences. The catch is contact data: each plan includes only a small monthly allotment of verified contacts, about 10 on the entry plan, then charges per contact.

    Best for
    EU teams comfortable managing their own sending who want ID plus light outreach.
    Pricing
    From ~$65/mo, public. Verified contacts are credit-metered.

    Watch-out: The credit meter makes real usage more expensive than the sticker price.

  6. 06

    ZoomInfo (WebSights)

    Enterprise sales intelligence.

    A huge sales-intelligence platform whose WebSights feature handles visitor ID. The database is enormous, but pricing is quote-only and annual with a three-seat minimum, and its person-level visitor ID is US-only, not designed for GDPR-covered UK and EU visitors. Chat and outreach are paid add-ons.

    Best for
    US enterprises already invested in the ZoomInfo ecosystem.
    Pricing
    Quote only, annual, auto-renewing. Median contract around $32,000 a year.

    Watch-out: Overkill and over-budget if you just want to identify and contact website visitors, and weak for EU visitor ID.

  7. 07

    HubSpot Breeze Intelligence (formerly Clearbit)

    Best if you live in HubSpot.

    Clearbit became HubSpot's Breeze Intelligence. It does enrichment, visitor identification (formerly Clearbit Reveal), and form shortening, and it shines when you are already a HubSpot customer. Pricing is credit-based and the data skews US.

    Best for
    HubSpot-native teams wanting reveal and enrichment inside the CRM.
    Pricing
    Credit-based, from around $75/mo; credits expire monthly.

    Watch-out: Best value only inside HubSpot, and users report cost rises since the acquisition.

  8. 08

    Warmly

    Signals and orchestration for US teams.

    Warmly combines visitor de-anonymisation with AI chat, AI outbound, and intent signals. Feature-rich, with a free tier, but the paid platform is priced for well-funded US teams and can get very expensive at scale.

    Best for
    US revenue teams wanting an all-in-one signals-and-orchestration platform.
    Pricing
    Free tier; paid plans from around $10,000 a year and up.

    Watch-out: Powerful but pricey, and US-centric.

  9. 09

    6sense

    Enterprise ABM, not really a visitor-ID tool.

    A full enterprise ABM and intent platform where visitor identification is a small part of a large, complex system. Genuinely powerful for big go-to-market teams, and priced accordingly.

    Best for
    Large enterprises running sophisticated account-based programmes.
    Pricing
    Quote only, multi-year contracts. Commonly $60,000 to $300,000+ a year.

    Watch-out: Vast overkill, and cost, for teams that simply want to identify website visitors.

  10. 10

    RB2B

    Person-level, US-only, simple.

    A newer, popular tool that identifies individual visitors, not just companies, and pushes them to Slack. It is US-only and person-level, powerful there but not designed for GDPR-covered EU and UK traffic. There is a free plan.

    Best for
    US teams wanting fast, person-level alerts.
    Pricing
    Free company-level plan; person-level from $79/mo, credit-based.

    Watch-out: US-only and person-level, so a poor fit for UK and EU businesses on privacy grounds.

Questions, Answered.

How does website visitor identification work?

Tools match a visitor's IP address to a B2B company database. Some, like RB2B, go further and identify individual people, which raises privacy questions in the EU and UK.

What identification rate should I expect?

Typically 20 to 40% of your B2B traffic, depending on your market and traffic quality.

Is it GDPR-compliant?

Company-level identification is generally fine in the EU and UK with the right lawful basis. Person-level, US-built tools are riskier for European traffic. Contaktly is built GDPR-first.

Is there a free option?

Leadfeeder, Warmly, and RB2B have free tiers. Contaktly offers a free account with no credit card and a 30-day identification guarantee, so you can prove it works before you pay.
