Which one is for you
Pick RB2B if
- Fits if your visitors are mostly in the US and you want names in Slack
- Works for a small team that will start on the free plan
Look elsewhere if
- Skip it if your traffic is outside the US, since only company-level ID applies there
- Tight if you want coverage: 15 to 20% on Starter and Pro, 35 to 45% on Pro+
- Pricey if you go over: extra resolutions are 45 cents on Starter and 25 cents on Pro and Pro+
- Watch out: business emails and most integrations need Pro or above
Pick Warmly if
- Fits if you are a funded B2B team with a sales rep ready to act on live visitor alerts
- Makes sense if you want identification and AI chat from one vendor and can sign a yearly contract
Look elsewhere if
- Skip it if you want self-serve: no plan can be bought without talking to sales
- Pricey if your budget is under $10,000 a year, which is where the cheapest plan starts
- Tight if you want the chatbot or agents, which sit on the $20,000 and $30,000 plans
- Watch out: the page does not say what a credit buys, and every tier starts at 10,000 a month
- Watch out: four quarterly payments of $4,875 come to $19,500, against $10,000 on the annual tab

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
