Several free alternatives to Blockify include BM: Country blocker IP blocker (4.9 stars, 115 reviews) which blocks countries, IPs, bots, and customers; Blocky Fraud Filter IP Blocker (4.7 stars, 144 reviews) with country blocking and fraud prevention; and EB: Fraud Filter, Bot Blocker (4.8 stars, 19 reviews) offering customer blocking, bot detection, and IP blocking. All provide similar core functionality with varying feature sets.

To set up IP blocking in Blockify, navigate to your Shopify admin > Apps > Blockify. Go to the IP Blocker section and add specific IP addresses you want to block. You can create up to 4 free rules or upgrade for unlimited blocking. The app automatically detects and blocks suspicious IP ranges, and you can set up custom rules based on visitor behavior patterns to prevent fraudulent checkout attempts.

Yes, Blockify can automatically cancel high-risk orders, but this feature is available only on Shopify Plus plans ($39.99/month). The app uses AI-powered fraud detection to identify suspicious orders based on IP location, VPN/proxy usage, and behavioral patterns. Once detected, high-risk orders are automatically cancelled before payment processing, helping you prevent chargebacks and financial losses from fraudulent transactions.

Blockify's content protection feature prevents content scraping by disabling right-click functionality, blocking copy-paste actions, and hiding page source code. This protects your unique product descriptions, images, and pricing from competitors and scrapers. The feature is included in premium plans and works seamlessly with your Shopify theme, ensuring your valuable content remains secure while maintaining a professional shopping experience for legitimate customers.
