RB2B alternatives: 7 website visitor ID tools compared

The closest RB2B alternatives for naming the people on your website are Knock2, Leadpipe, Warmly and Intent Leads. Vector suits ad-heavy ABM teams, and Leadfeeder and Snitcher fit if knowing the company is enough. The real differences are in how they charge and what comes with each person: a monthly credit plan, an annual contract or a price per person, and whether you get a phone number.

Below: what RB2B costs today, the alternatives side by side, what 600, 2,500 and 10,000 identified people a month cost on each, and when RB2B is still the better choice. Every price was checked on the vendor's own site in November 2026 and is linked.

What RB2B does and costs (as of November 2026)

RB2B identifies US visitors at the person level and visitors anywhere at the company level (how it works). Its pricing page lists four plans:

A few details matter when you compare:

• Match rate: RB2B's pricing page lists 15–20% contact-level coverage on Starter and Pro, and 35–45% on Pro+.
• Overage: 45¢ per extra identified visitor on Starter, 25¢ on Pro and Pro+.
• More sites: extra domains cost $99/mo (up to 5) on Pro and Pro+.
• No phone numbers. RB2B's help center lists phone numbers among the things it doesn't provide.
• The free plan no longer names people. Since January 22, 2026, person-level visitors on Free appear masked (RB2B Free plan).
• Credits cover more than people. Each identified visitor uses a credit, and RB2B suggests turning off tracking of global visitors you don't target to save them.

Why teams look for an RB2B alternative

• They need phone numbers, not just a LinkedIn URL and an email.
• The free plan stopped showing names, so after RB2B's 7-day trial, person-level ID means a paid plan.
• Their traffic is uneven. A monthly plan costs the same in a quiet month.
• They want more than visitors: people researching their category who haven't visited yet, or a contact database to search.
• They need people outside the US. Switching won't fix that: RB2B, Knock2 and Intent Leads identify people in the US only, and Leadpipe's plans name US visitors.

RB2B alternatives at a glance

What 600, 2,500 and 10,000 identified people a month cost

List prices, using the smallest published tier that covers each volume:

How to read it:

• Plans assume you use every credit. A plan costs the same whether or not your traffic shows up. Per-person billing charges only for the people delivered, which favors small or uneven traffic.
• At high volume, RB2B Pro+ is cheaper per person. From about 7,500 identified people a month, Pro+ costs the same as Intent Leads or less ($649 vs $650 at 7,500, $949 vs $1,487.50 at 20,000), if you use the credits.
• Match rates differ, so the same traffic yields different counts. Cost per person you'd actually contact, on your own traffic, is the number that matters.
• Credits aren't always one per person. Knock2 takes 6 credits for a contact and 1 for an account from one pool (Knock2 pricing).
• Intent Leads has a $250 minimum top-up. The balance is spent per person and only expires after 3 months with nothing added or spent.

The alternatives, one by one

Knock2

Person-level ID for US traffic and account-level ID everywhere else. Plans run from $165/mo (600 contacts) to $830/mo (7,500 contacts) billed annually, or month to month, with a 7-day free trial (pricing). Every plan includes Slack and Teams, HubSpot, Salesforce and Attio, webhooks, an API and MCP access. Its person-level data includes phone. Knock2 says it identifies the person on 62% of US engaged sessions, using Google Analytics' definition of an engaged session (10 seconds or more, or 2+ page views).

Choose it if you want a high published match rate, phones and native CRM sync on a fixed plan.

Leadpipe

Identifies US visitors by name, with the company behind a visit when there's no person match, plus phone enrichment. Pro runs from $147/mo for 500 unique IDs to $1,879/mo for 20,000, with 260+ integrations and CSV export. Webhooks and the full API start on Platforms, from $2,499/mo. A white-label Agency plan starts at $3,500/mo for 100,000 IDs (pricing).

Choose it if you're an agency that wants visitor ID under its own brand.

Warmly

Visitor identification as part of a larger inbound platform. Its pricing page lists AI Web-Deanonymization from $10,000/yr (or $4,875 a quarter), Inbound Chat from $20,000/yr and AI Inbound Autopilot from $30,000/yr.

Choose it if you want visitor ID, live chat and automated inbound follow-up from one vendor, and have the budget.

Vector

An ABM and advertising platform: signals, scoring, contact-level ad audiences, LinkedIn bid agents and attribution, with unlimited seats. One annual contract from $36,000/yr, sized by your monthly site visitors and ad spend (pricing).

Choose it if paid ads are a big part of your pipeline and you want visitor data feeding them.

Leadfeeder (Dealfront)

Company-level identification with unlimited users and domains. Lite is free (the last 100 companies, 7 days of history). Discover starts at €79/mo, Activate at €369/mo (adds verified emails and phones, paid with credits) and Scale at €599/mo, all billed annually (pricing).

Choose it if you sell to accounts, or much of your traffic is outside the US, where the person-level tools here can't name anyone.

Snitcher

Priced by unique companies identified: $49/mo for up to 50, up to $529/mo for 5,000, billed annually ($79 to $779 month to month), with every feature on every plan. HubSpot, Salesforce, Pipedrive, Slack, Zapier and webhooks are included. There's a 14-day free trial and no long-term contract (pricing). Its FAQ describes its focus as company-level, with individual contact details only when you choose to reveal them.

Choose it if company-level is enough and you want a low price with no long-term contract.

Intent Leads

Person-level identification for US visitors, priced per person instead of by plan. Identified people arrive on your webhook within about 15 minutes, and in the API and dashboard. Each comes with name, title, company, business email, LinkedIn and mobile when we have them, every mobile with its own do-not-call flag, plus the pages they viewed. See website visitor ID.

• Pricing: 10¢ a person for the first 2,500 a month, 8¢ to 7,500, 6.7¢ to 20,000, then 5¢ (pricing). Each person is charged once a month, however often they come back. Set a monthly cap on each site so a traffic spike can't run up the bill.
• More than visitors: the same balance buys intent leads, people researching your topics who haven't visited yet, and Search across more than 350 million US contacts. Visitors and intent leads count toward the same monthly price bands.
• Built for code and agents: API, CLI, MCP server and signed webhooks on every account. Agencies give each client its own workspace.
• Limits: US visitors only, and never people in the UK, the EU or Switzerland; no company-level ID. Expect roughly 15–20% of US visitors on a typical B2B site, since Safari and iPhone visitors are rarely identified. There are no native Slack or CRM apps: visitors arrive by webhook, API or CSV.

Choose it if you want mobiles, pay only for the people delivered, or want intent data and contact search in the same account.

When RB2B is still the better fit

• You want names in Slack in minutes and a free company-level plan to start.
• You need company-level ID for non-US traffic in the same tool as US person-level ID.
• You identify thousands of people a month and use every credit. From about 7,500 a month, Pro+ costs less than Intent Leads' list price and publishes a higher match rate (35–45%).
• You rely on its native Clay, HubSpot or Salesforce integrations and want them from $149/mo.

How to test an alternative on your own traffic

1. Run two tools side by side on the same pages for the same two weeks. Check your cookie banner setup first; our cookie consent guide shows how.
2. Count identified people against US visitors, not total sessions. Bots and non-US traffic make every tool look worse on raw numbers.
3. Spot-check 20 people. Is the company right? Does the job title fit the pages they read?
4. Count who you can reach: a business email that passes validation, and a mobile.
5. Divide the cost by the people you'd contact. That's the only per-person price that matters.

Try Intent Leads on your own traffic

Add your site with a monthly cap and paste one script. You pay 10¢ per identified person, falling to 5¢ as your month grows, from a prepaid balance: no subscription and no seats. Each person is charged once a month however often they come back, and you're never charged again that month for someone you already have. Counts and samples for intent leads and Search are free.

Frequently asked questions

Is RB2B free?

There's a free plan, but since January 22, 2026 it shows companies only: 150 a month, with person-level visitors masked. Names and LinkedIn URLs start on Starter ($79/mo), and business emails on Pro (from $149/mo), as of November 2026.

Does RB2B give phone numbers?

No. RB2B's help center lists phone numbers among the information it doesn't provide. Knock2, Leadpipe, Leadfeeder (on Activate, with credits) and Intent Leads all include phone numbers. Intent Leads flags each mobile with its own do-not-call status.

Does RB2B work outside the US?

Only at the company level. Person-level identification is limited to US visitors, as it is for Knock2 and Intent Leads. Intent Leads doesn't identify visitors outside the US at all.

What is the cheapest RB2B alternative?

For company-level ID only, Leadfeeder Lite and RB2B Free cost nothing, and Snitcher starts at $49/mo billed annually. For named people, per-person pricing is cheapest at low and uneven volume: 2,500 people cost $250 on Intent Leads against $349 on RB2B Pro. Above about 7,500 people a month, RB2B Pro+ costs less if you use the whole plan.

What counts as a credit on RB2B?

One identified visitor delivered to you, either a person or a company. A credit covers that visitor's activity for a rolling 30 days, so repeat visits in that window don't use more. If you downgrade mid-cycle, RB2B doesn't refund unused time or credits (Free plan FAQ).
