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 paid 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 savings calculator to see your saving before switching.
All Stack Architect tools are specifically built to operate within Make.com's free plan limits, including its two-active-scenario cap, which is why the stack is assembled as one scenario with router branches rather than four separate ones. Stores processing higher order volumes can upgrade to Make.com's Core plan at $9/month: still far below the paid apps it replaces, where Elevar's Core plan alone is $225/month.

Stocky Swap is the free replacement for its order log. It logs every paid order to Google Sheets via a Make.com automation. It does not calculate stock on hand; Shopify Admin does. Use the Stocky Migration Risk Scorer to assess your complexity before migrating. Setup takes under 5 minutes. Paid alternatives such as Prediko cost $49+/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 Meta's Conversions API. 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.
