Blockify Fraud Filter, Blocker
Best for: Stores whose fraud and abuse arrive from identifiable countries, IP ranges, or VPNs.
Why choose it
- 4.9 stars across 1,569 reviews and live since March 2018. No other app in this category has that record.
- The free plan covers four block rules and four redirect rules, which is enough to stop one problem country at no cost.
- Blocking happens at the storefront visit, so a blocked visitor never reaches your checkout, your inventory, or your order table.
- Redirect mode lets you send a visitor somewhere else instead of blocking, which is a gentler first step than a hard block.
When not to choose it
- It decides using the visitor, not the order. Fraud from a clean residential IP with a real address will pass straight through.
- Auto-cancel of high-risk orders and conditional checkout blocking sit on the $39.99 Shopify Plus tier. Check the tier before you compare it against a cheaper plan elsewhere.
Setup notes
- Start in redirect mode rather than block, so you can see what you would have stopped before you stop it.
- Watch sessions and revenue for any country you block, for at least a week after the rule goes live.
- Pricing
- Free plan, then Premium $9.99, Enterprise $19.99, and Shopify Plus $39.99 a month. Three-day trial on paid plans. Read on the App Store 2026-08-23.
- Example
- A store losing money to one country blocks it on the free plan and pays nothing. At that scope no rules engine beats free, ours included.
