1. 1LookupTop pick, our product

Best for a named person with a work email on every identified visit

Pick 1Lookup when you want the person behind a visit, not just the company: a name, work email, LinkedIn profile URL, job title and company for each identified visitor, and a phone number for about 1 in 4, anywhere outside Europe, billed per identified person and delivered by API, webhook or CSV. It starts with a 7-day free trial and a short access application.

Starting price: $99 a month for 4,000 identified people.
Free option: Visitors who are not identified are never billed; it starts with a 7-day free trial and a short access application.
Where it wins: 5 credits for each identified person, and nothing for a visitor who is not identified, so the bill follows the people you actually get.

The price of one identified person on each 1Lookup plan, falling from Starter to Enterprise because a larger plan buys credits at a lower price, while the person always costs the same number of credits

2. RB2B

Best for a free plan and a price printed at every volume

Pick RB2B when you want to start on a free plan that has no end date, or you need a price printed at every step up to 12,500 identified people a month, with Slack and Teams alerts on every plan.

Starting price: $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).
Free option: A Free plan with no end date: company-level identification and 150 resolutions a month, pushed to Slack, with no person-level identification and no email addresses.
The catch: Person-level identification is US only: the page says Company-Level ID is global on every plan, but contact-level (person) ID covers US visitors only.

This is how much work a switch takes.

On the 1Lookup side the move is one script on the pages where you want visitors identified and a place for the records to go: an API, a webhook or a CSV. Knock2 also auto-prospects from the accounts it sees, so decide whether you still need that before you cancel, and send 1Lookup's records to the place your prospects go today. Run Knock2 and Website Visitor ID side by side on the same pages for a month and compare the number of named people you get before you cancel anything.

How Website Visitor ID bills: every visit to your pages is seen, the visitors who can be named become identified people with a work email and are billed once each, and the visitors who cannot be named are dropped at no charge

The same identified-person record for a fictional visitor arriving three ways from Website Visitor ID: read by API, posted to your URL by webhook, or downloaded as a CSV file, with the same fields each time

These are the questions people ask about Knock2 alternatives.

What is the best Knock2 alternative?

1Lookup, if you want a named person with a work email for each identified visitor, from $99 a month for 4,000 identified people. Knock2 stays the better fit if you want auto-prospecting in the same tool as identification: Knock2 includes contact and account identification and auto-prospecting on every plan, and annual billing takes two months off.

Is there a cheaper Knock2 alternative?

On month-to-month billing 1Lookup costs less at 1 to 7,500 people a month. Knock2 never costs less than a 1Lookup plan in its published range.

Does Knock2 identify people or companies?

Both: Knock2 identifies US contacts and the accounts they work for. A contact uses 6 credits from the monthly pool and an account 1, and its plans are named by the contacts they cover.

What does 1Lookup return for each visitor?

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. 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. Knock2's own page says "Person-level identification runs on US traffic only, by design." (https://www.knock2.ai/pricing), so it names US visitors only, where 1Lookup names visitors worldwide outside Europe.
