How we grade them
| 2.0GPAConvertBoxFair | 2.6GPAOptiMonkGood | |
|---|---|---|
| Value for money | C$495 once for 250,000 views a month on 10 sites, far more than a 20,000-visitor site needs. Spread over two years that's about $20.63 a month, just above the cheapest quarter here, with nothing more to pay after. But the deal may close or rise without notice. | DEvery page load counts, so a site with 20,000 visitors viewing a few pages each goes past Essential's 50,000-pageview top. That means Growth: $69 a month billed yearly ($828), or $99 monthly, at the dear end of popup tools here. Every feature is on every plan, at least. |
| Free plan and trial | FNo free plan and no free trial. The page offers 14 days risk-free, but that's a refund promise, not a trial: you pay the $495 before you see it on your site. | BFree forever: 10,000 pageviews a month on 1 domain, every feature, the AI agent with 1,000 credits a month, and no OptiMonk branding. A small blog could live on it, though a busier site will pass it. |
| Features | BSlide-ins, modals, sticky bars, takeovers and embedded boxes, targeted on your email tool's lists and tags as well as pages, scroll and exit intent. Multi-step quizzes, countdowns, personal text and A/B tests too. It covers the whole job. | AAn AI agent that designs, writes, publishes and A/B tests popups, and an MCP server so you can build them from Claude, ChatGPT or Cursor, which no other tool here has. Spin-to-win, quizzes, upsells and 1,000+ examples too, with nothing held back by plan. |
| Ease of use | CNo rating on record. Templates and a drag-and-drop editor help, but the best part, targeting by your email tool's tags, means connecting that tool and building rules, and mobile gets its own design. | CNo rating on record. Describing a popup in a sentence is about as easy as it gets, but you still add it to your store, keep an eye on AI credits and pageviews, and check what the agent makes. |
| Platforms and integrations | BWorks on any site, with direct links to ActiveCampaign, ConvertKit, Drip, HubSpot, Keap, Klaviyo and Mailchimp, a WordPress route and webhooks for Zapier. No desktop or phone app. | BWeb, with 60+ integrations such as Shopify and Klaviyo, plus Zapier, webhooks and an API, and it can be run from Claude, ChatGPT or Cursor. No desktop or phone app, so B is the top. |
| Best for | paying once for targeted popups and quizzes | popups built by an AI agent for online stores |

- There is no free plan or free trial; the page offers to let you try it for 14 days risk-free.
OptiMonk
- Every page load counts as a pageview whether or not a popup shows; at the limit, campaigns pause until you upgrade or the month resets.
