How we grade them
| 1.8GPAOptinMonsterWeak | 2.2GPAProveSourceFair | |
|---|---|---|
| Value for money | DGraded on a site with 20,000 visitors, more than Plus's 10,000 impressions a month, so it's Pro: $870 a year at renewal, $72.50 a month, after a $444 first year. That's dearer than most popup tools here. Pro does bring exit intent, which the cheaper plans lack. | CStarter is $24 a month billed annually for 20,000 visitors, inside the $9 to $29 range but at the dearer end; monthly billing is $29. |
| Free plan and trial | FNothing free and no trial. There's a 14-day refund, but a money-back promise isn't a trial: you pay before you see it on your site. | CFree plan with all features for 1,000 monthly unique visitors, with ProveSource branding on notifications. |
| Features | BLightboxes, floating bars, slide-ins, full-screen overlays and coupon wheels, 700+ templates, targeting by page, time, scroll and device, A/B tests and revenue tracking. Exit intent and geolocation sit on the dearer plans. | CRecent activity, live visitors, reviews, display rules and analytics. It is notifications only: the popup widgets are a separate product. |
| Ease of use | CNo rating on record. Templates and a drag-and-drop builder help, but you have to add its code to your site, or use the WordPress or Shopify route, and set up targeting rules before anything shows. | CNo rating on record; you install a snippet and connect your tools. |
| Platforms and integrations | BWorks on any site you can add JavaScript to, with plugins and guides for WordPress and Shopify, and sends sign-ups to Mailchimp, Constant Contact, ActiveCampaign and ConvertKit. Zapier needs Pro. No desktop or phone app. | BWeb only, with eight integrations listed. |
| Best for | pop-ups that grow an email list | social proof notifications for a small website |

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.
