We compared the leading free popup apps so you can pick the right one for your store.
Popups remain one of the highest-ROI tools in ecommerce — a well-targeted popup can convert a meaningful share of visitors who would otherwise leave. The good news: you don't have to pay to get started. Here are the best free Shopify popup apps in 2026.
A focused, affordable app with a real free plan. Supports email, discount, and SMS popups plus banners and Shopify Flow, with more formats like exit-intent and spin-to-win on the roadmap. Paid plans start at just $3.99/month. Best for stores that want simple, effective popups without a big bill.
A broader marketing suite with a limited free tier. Good if you want email sending built in, but costs rise with your contact list.
A general-purpose popup builder with a free plan. Works across platforms, so it's handy if you run sites beyond Shopify.
Advanced targeting and AI features aimed at higher-traffic stores; the free tier is limited.
Powerful personalization, but no lasting free plan and higher pricing — better for larger budgets.
