Free Shopify Automation.
Stack Architect's free tools cover the four most expensive Shopify app categories: inventory management (Stocky Swap), server-side ad tracking (CAPI Shield), workflow automation (Make.com), and email and CRM (Systeme.io). Together they replace a typical $500–$1,500/month app stack at $0. Before deploying, the free diagnostic calculators help you identify your biggest leaks first.
The key insight: most of these apps are just moving Shopify data you already own from one place to another, and charging you monthly for the privilege. Use the Klaviyo Migration Savings Calculator to see your exact saving before switching.
All Stack Architect tools are specifically built to operate within Make.com's free plan limits. Stores processing higher order volumes can upgrade to Make.com's Core plan at $12/month — still 95% cheaper than the paid apps it replaces. Create your free Make.com account here →
Stocky Swap is the free replacement — it tracks inventory movements and stock levels in Google Sheets via a Make.com automation. Use the Stocky Migration Risk Scorer to assess your complexity before migrating. Setup takes under 5 minutes. Most paid alternatives charge $49–$199/month. Stocky Swap is permanently free.
CAPI Shield does the same thing free — it uses Make.com to capture Shopify purchase events server-side and send them directly to Google Ads and Meta Ads via their Conversions APIs. Use the Meta EMQ Score Estimator to see exactly how much you're losing before you build, and the Attribution Gap Calculator to understand your current data discrepancy.
