How we grade them
| 2.6GPAOptiMonkGood | 2.2GPASleeknoteFair | |
|---|---|---|
| Value for money | 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. | CSleeknote counts visitors, not pageviews, so a site with 20,000 visitors fits Core: $55 a month billed yearly ($69 monthly) for up to 25,000. That's toward the dear end of popup tools here, with no cap on campaigns or domains. Spin-to-win and quizzes take it to $76. |
| Free plan and trial | 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. | CNo free plan, but a 14-day free trial with every product and feature, and no credit card needed. After that, campaigns stop showing until you pick a plan. |
| Features | 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. | CPopups to collect emails, sell products and guide shoppers, 100+ templates, unlimited campaigns and domains, and spin-to-win, scratch cards, quizzes and calendars as an add-on. Nothing on record about A/B tests or targeting rules, and the games cost extra. |
| Ease of use | 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. | CNo rating on record. Templates and building without code help, and phone, chat and email support come with every plan, but you still build campaigns and decide when they show. |
| Platforms and integrations | 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. | BWeb, with direct links to Klaviyo, Mailchimp, HubSpot, ActiveCampaign, Omnisend, Drip, Campaign Monitor and Shopify. No desktop or phone app, so B is the top. |

Worth knowing
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.
- Each subdomain counts as a separate domain, and Essential allows only 2.
- The agent draws on a monthly allowance of AI credits; more credits mean moving up a plan.
- Prices exclude VAT; EU customers without a valid VAT number pay 27% Hungarian VAT.
Sleeknote
- There is no free plan; after the 14-day trial, campaigns stop showing until you pick a plan.
- Gamification is an add-on: Core and Gamification costs $76 a month yearly against $55 for Core alone.
- Going over the visitor limit never switches campaigns off, but past 100% the account is moved up to the next plan.
- A money-back guarantee covers 30 days on monthly plans and 100 days on annual plans.
