| Tool | Price | What you get (versus cost) |
|---|---|---|
| PopupKit | * Personal – $31.6/yr * Professional – $79.6/yr * Agency – $119.6/yr | One-time or annual license gives unlimited pageviews, full feature set, including gamified popups, WooCommerce, etc. |
| OptinMonster | * Basic – $84/yr * Plus – $228/yr * Pro – $348/yr * Growth – $588/yr | SaaS with strong features (A/B testing, targeting, analytics, e-commerce integrations), but the cost scales with site count/impressions. |
| OptiMonk | * Available in free version with 10,000 Pageviews/mo. * Essential – $228/yr * Growth – $828/yr * Premium – $2,148/yr | Offers free tier; pricing based on pageviews; inclusive features (all features included in base plan), so you don’t have to keep upgrading for “features”, only for volume. |

OptinMonster shines for its strong feature set and advanced targeting/integrations, but you need to pay more.
PopupKit offers the best cost if you are using WordPress or require many site setups with unlimited pageviews.
Performance and Impact
| Aspect | PopupKit | OptinMonster | OptiMonk |
|---|---|---|---|
| Script loading/architecture | WP plugin that injects scripts via the site. Generally lightweight, but it depends on the theme/plugins and caching. | Cloud service with async/defer embed options and recommended non-blocking install. | CDN-served embeds with platform integrations (Shopify etc.) and are designed for lightweight delivery. |
| Mobile behavior/controls | Supports device targeting, but performance depends on theme responsiveness. | Responsive by default, mobile preview, and mobile-specific targeting/settings. | Strong mobile controls (hide/show elements, mobile previews & optimizations). |
| Heavy assets & CLS risk | Manageable, avoid large images/fonts in popups; WP site may add extra assets. | Vendor advises limiting heavy assets. Use placeholders to avoid CLS. | Built for e-commerce that often includes mobile-friendly patterns to reduce CLS. |
| A/B testing & experimentation | Basic A/B capability, but more manual measurement is often required. | Robust built-in A/B testing and variant analytics. | Built-in A/B testing and campaign experimentation geared toward e-commerce use. |
| Analytics & attribution | Basic analytics that integrates with WP tools and external analytics. | Good analytics and integrations with CRMs and analytics platforms for tracking conversions. | Strong ecommerce attribution (revenue, AOV) and direct integrations (Shopify/GA) for campaign ROI. |
| Reported conversion impact | Effective for lead capture on WP sites. Impact varies widely with targeting and site setup. | Proven across many use-cases for list growth and lead gen. Large template + trigger set yields strong results. | Optimized for e-commerce. Often shows measurable revenue/AOV lift when product/cart data is used. |
| Best use case for performance vs impact | WP sites that want a lightweight, integrated plugin. | Brands need flexible campaigns with strong A/B testing, and low site-impact when configured correctly. | E-commerce stores that prioritize revenue attribution, personalized onsite offers, and mobile optimization. |
| Implementation risk (scale / complexity) | Lower complexity for WP users, but higher risk on complex WP stacks. | Moderate. But it could be steeper for many features. Still scalable for large sites. | Moderate to high if integrating advanced e-commerce features. |
➡️ If your primary KPI = revenue / AOV / ecommerce lift, start with OptiMonk and enable its ecommerce analytics. Monitor GA4 revenue events to attribute properly.
➡️ If your primary KPI = email list growth & flexible campaign types and you want low technical friction + templates, use OptinMonster and follow its async install + performance guidance.
➡️ If you run WordPress and want something lightweight you control inside WP, try PopupKit (but test on a staging site to check theme/plugin interactions).
