At a glance

Here is where 1Lookup wins against RB2B, and where RB2B still wins.

Both put a name on the people behind website visits, RB2B for US visitors only and 1Lookup worldwide outside Europe. RB2B is a sales tool: it sells a monthly plan with an allowance of resolutions, one for each identified visitor, and pushes the leads to Slack, Teams or a CRM. 1Lookup sells the same result as a data product: 5 credits for each identified person, nothing for a visitor it cannot identify, from a credit balance that also pays for phone, email and IP lookups.

1Lookup logo1lookupWhere 1Lookup wins
  • A lower entry price: $99 a month for 4,000 identified people, against $149 a month for 600 identified people on RB2B Pro, and a month of up to 4,000 people is the cheaper bill on 1Lookup
  • You pay only for identified people: a visitor 1Lookup cannot identify costs no credits
  • The same credits also pay for phone, email and IP lookups, so one balance covers the identified person and the checks you run on them
  • No seat fees, and unused subscription credits roll over for up to 3 months
  • Work email addresses and every delivery method come with every plan, where RB2B starts email addresses at Pro

What it costs

From $0.01

per identified person (5 credits); $0.02475 on Starter

RB2B logoWhere RB2B wins
  • A free plan that lasts: RB2B's Free plan gives 150 company-level resolutions a month with no end date, and every account starts with a 7-day full-featured trial without a card.
  • The price per person falls with volume: $149 for 600 resolutions on Pro is $0.2483 each, $349 for 2,500 is $0.1396 each, and $849 for 12,500 on Pro+ is $0.0679 each.
  • A coverage claim of its own: RB2B's comparison table prints 15-20% contact-level coverage on Pro and 35-45% on Pro+, which uses what it calls Premium Resolution and an identity graph waterfall.
  • Built for the sales workflow: Slack and Teams on every plan, and Clay, HubSpot, Salesforce, Zapier, webhook, CSV export and over a dozen other products on Pro and Pro+, plus Hot Pages and Hot Leads filters that flag high-intent visits.
  • A wide range of volumes: Pro+ allowances run from 600 up to 2,500,000 resolutions a month, with a price printed for each step up to 12,500.

What it costs

$79 a month for Starter (300 resolutions, LinkedIn URLs pushed to Slack or Teams, no email addresses); $149 a month for Pro, which adds business email addresses and all integrations (600 resolutions)

Short answer

RB2B sells monthly plans by resolutions, one per identified US visitor: Pro runs from $149 for 600 to $349 for 2,500, and Pro+ from $499 for 5,000 to $849 for 12,500. 1Lookup charges 5 credits per identified person and nothing for an unidentified visitor, from $99 a month for 4,000 identified people.

What replaces what

Here is which 1Lookup product matches each RB2B job.

RB2B counts one resolution for each identified website visitor and sells a monthly allowance of them. This is the same unit on 1Lookup, one identified person, billed in credits from a balance that also pays for other lookups, with unused subscription credits rolling over for up to 3 months.

Side by side

Both products are measured on the same criteria, using RB2B's own published numbers.

A real result

This is what one 1Lookup result looks like.

  1. Add one script to your site

    Put the script on the pages where you want visitors identified, such as your pricing and product pages. There is nothing for your visitors to fill in.

  2. We identify the visitors we can, worldwide outside Europe

    Each visit from a country outside Europe is matched to a person. A visit we cannot put a name to is dropped, and you are not billed for it.

  3. The person reaches you by API, webhook or CSV

    Each identified person is delivered once as flat, structured JSON, or collected into a CSV. Every identified person bills 5 credits.

This is RB2B’s pricing page, as we read it.

Every RB2B figure above is taken from this page. It is reproduced here so you can check the numbers against the source instead of trusting our transcription of them, and the caption links straight to it. Prices change; the capture date says how fresh this is.

Who it is for

Pick 1Lookup or stay with RB2B depending on the job in front of you.

1Lookup logo1lookup

Choose 1Lookup if

you want the lower monthly bill at 1 to 12,500 identified people a month: a Starter month covers 4,000 identified people for $99 on one credit balance that also pays for phone, email and IP lookups, with no charge for visitors that stay anonymous.

RB2B logoRB2B

Consider RB2B instead if

you want a free plan or leads pushed into Slack: RB2B prints a Free plan with a 7-day trial, and its Pro and Pro+ plans cost less than 1Lookup at people a month, with a price listed up to 12,500 resolutions a month.

Questions

People ask these questions before they switch from RB2B.

What is the best RB2B alternative?

If you want the sales workflow around the data, with Slack and Teams alerts, high-intent page filters and a free plan to start on, RB2B is built for that. If you want identified people as data you can call by API, webhook or CSV, at 5 credits per person on a balance that also pays for phone, email and IP lookups, 1Lookup's Website Visitor ID is the alternative. Website Visitor ID requires approval. Start the 7-day free trial, then send the short application inside your account: we review each website before we switch on visitor identification.

How much does RB2B cost?

RB2B prints monthly prices by resolutions. Free is 150 company-level resolutions with no person-level identification. Starter is $79 for 300, with LinkedIn URLs and no email addresses. Pro, with business email addresses and all integrations, is $149 for 600, $249 for 1,250, $349 for 2,500. Pro+ is $499 for 5,000, $649 for 7,500, $799 for 10,000, $849 for 12,500. Above 12,500 you contact sales. Extra resolutions cost 45 cents on Starter and 25 cents on Pro and Pro+, and additional domains are $99 a month. Checked October 2026.

How much does 1Lookup charge for an identified visitor?

5 credits for each identified person, and nothing for a visitor who is not identified. Starter ($99 a month) covers up to 4,000 identified people at $0.02475 each, Growth ($299 a month) covers up to 17,000 identified people at $0.0176 each, Professional ($799 a month) covers up to 50,000 identified people at $0.016 each and Enterprise ($1,999 a month) covers up to 200,000 identified people at $0.01 each. Credits come from a plan that also pays for every other 1Lookup product, and unused subscription credits roll over for up to 3 months.

Is 1Lookup cheaper than RB2B?

On month-to-month billing 1Lookup costs less at 1 to 12,500 people a month. RB2B never costs less than a 1Lookup plan in its published range. At 250 identified people a month, 1Lookup Starter costs $99 and RB2B Pro costs $149. At 1,000 identified people a month, 1Lookup Starter costs $99 and RB2B Pro costs $249. At 1,500 identified people a month, 1Lookup Starter costs $99 and RB2B Pro costs $349. Prices are month to month on both sides, and RB2B prints no annual discount.

What does RB2B count as a resolution, and what does 1Lookup count?

RB2B counts one resolution for each website visitor it identifies, and a plan holds a monthly allowance of them. 1Lookup counts one identified person, 5 credits each, and a visitor it cannot identify is not billed.

What does RB2B include that 1Lookup does not?

RB2B pushes identified leads into Slack and Teams, connects to Clay, HubSpot, Salesforce, Zapier and more on Pro and Pro+, and adds Hot Pages and Hot Leads filters for high-intent visits, a free plan with no end date and a 7-day trial. 1Lookup delivers identified people by API, webhook or CSV and leaves the workflow to your own tools.

Which visitors does 1Lookup identify?

Website Visitor ID identifies visitors worldwide outside Europe: every country except the European Union, Iceland, Liechtenstein, Norway, the United Kingdom and Switzerland. A visitor it cannot identify, wherever they are, costs no credits, because only identified people are billed. RB2B's own pricing page says "Contact-level (person) ID is US only", and the same page lists no phone number on any plan, where 1Lookup returns a phone number for about 1 in 4 identified people.

What comes back for each identified person?

Identified people come back by API, by webhook or in a CSV file, each with a name, a work email, a LinkedIn profile URL, a job title and a company, and a phone number with its do-not-call flag for about 1 in 4 people.

Do unused credits carry over?

1Lookup subscription credits roll over for up to 3 months, so a quiet month does not waste a plan. RB2B's pricing page prints a monthly resolution allowance and a price for each extra resolution.

Is RB2B worth it in 2026?

For a team that wants identified leads pushed into Slack and a CRM, yes, and its free plan and trial let you test the match on your own traffic first. Its Pro and Pro+ prices per person fall steeply with volume, from $149 for 600 to $849 for 12,500. If your volume is under 4,000 a month, or you want the data through an API on a shared credit balance, compare 1Lookup's per-person price.
