Website visitor identification tools · who visited your site

Pick Instantly if you want to email the people who visit your site. It names US visitors and runs the email campaign on the same plan, from $85 a month billed monthly.

Pick RB2B if you want a Slack alert that names the person who visited. Starter sends their LinkedIn profile for $79 a month, and RB2B lists monthly prices only.

Pick Leadfeeder if you want company names for free. Lite shows the last 100 companies a month at $0.

Pick Snitcher if you want a paid plan priced by the number of companies you identify. It starts at €49 a month billed yearly, or €79 billed monthly, for up to 50 companies a month.

Pick Vector if you can sign a yearly contract. Its plans start at $36,000 a year.

Company-level identification is close to free. RB2B Free, Leadfeeder Lite and Instantly’s company-only matches all cost nothing.

Person-level identification costs money. Instantly charges 3 credits per resolved profile. RB2B starts at $79 a month for LinkedIn profiles and $149 a month for email addresses.

• Instantly: 3 credits per resolved profile. Starter is $85 a month billed monthly with 1,500 credits.
• RB2B: Free $0 a month for 150 resolutions. Starter $79 a month for 300. Pro from $149 a month for 600. Pro+ from $199 a month.
• Snitcher: from €49 a month billed yearly, or €79 billed monthly, for up to 50 companies a month.
• Leadfeeder: Lite free. Discover from $79 a month billed yearly, or $113 billed monthly. Activate from $369 a month billed yearly, or $527 billed monthly.
• Vector: from $36,000 a year, on a yearly contract.
• Warmly: from $10,000 a year billed yearly, or $4,875 a quarter billed quarterly. Warmly says HubSpot is buying it, so its plans may change.
• Koala says it is shutting down, so pick another tool.

The math: on October 21, 2026 prices, to name 500 people a month and get their emails:

• Instantly Starter: 500 × 3 = 1,500 credits, all of Starter’s credits, for $85 a month billed monthly. The email campaign is part of the same plan.
• RB2B Pro: $149 a month covers 600 resolutions with email addresses. You need a second tool to send the emails.
• RB2B Starter: overage, the price per resolution past the plan’s number, is $0.45. So $79 + (500 minus 300) × $0.45 = $169 a month, with no email addresses.

Credits you spend on other Instantly jobs, like finding leads, lower the count of people it can name.

Instantly’s help center says Website Visitors works for US traffic only. RB2B says the same for person-level matches.

For visitors from other countries, expect the company name at best.
