Stack Architect
Free tools that replace paid Shopify apps — server-side tracking, inventory, email, TikTok CAPI, P&L reporting, and automation stability. Built for store owners tired of paying $700+/month for things that should be free.
What Stack Architect Is
Stack Architect is a collection of six free tools and guides that collectively replace the paid Shopify apps most stores spend $500–$900 per month on. Each tool uses Make.com's free automation tier, Google Sheets, and Systeme.io's free plan to achieve the same technical outcome as paid alternatives — without any monthly subscription, developer cost, or code.
The tools are free forever. Affiliate links on the site keep the resource funded — we only recommend tools we use ourselves, and they cost you nothing extra.
Why It Exists
The Shopify app ecosystem is built around recurring revenue. Tracking apps charge $149–$299/month for server-side conversion data that costs nothing to implement directly. Inventory apps charge $29–$199/month for Google Sheets sync that takes four minutes to build. Email platforms charge $150–$400/month for automation sequences that free tools replicate entirely.
Stack Architect exists to show store owners that the technical outcomes they are paying for are achievable at $0 — and to give them the exact tools and guides to do it in under six minutes per workflow.
