I build and document free, open-source automation tools for Shopify store owners. Every guide on this site comes from hands-on implementation work — building Make.com scenarios, configuring server-side tracking APIs, and testing every build hands-on before it's published. The same architecture that Elevar charges $300/month and Triple Whale charges $129/month for — released here free, with the full source on GitHub, step-by-step setup, and no upsell.
Where this knowledge comes from
Stack Architect exists because of a pattern I kept seeing in the Shopify ecosystem: store owners paying $149–$299/month for server-side tracking tools that do little more than route a Shopify Order webhook through an automation platform. I built the first version of CAPI Shield myself — configuring the Meta Conversions API directly via Make.com — and it sends the same server-side events to Meta that the paid tools do, at $0.
That pattern repeated across every category. Inventory management. P&L reporting. TikTok Events API. Email automation. In every case, the paid app was charging monthly for configuration work that takes under 10 minutes to replicate directly. So I documented all of it — step by step, with the exact API endpoints, field mappings, and Make.com scenario structures — and published it free.
The full source for every tool is public on GitHub, so nothing here is a black box. Anything I describe can be inspected, forked, and rebuilt independently — which is more than any of the paid alternatives offer.
Every number on this site is sourced or clearly framed. The Event Match Quality target (7+) is what well-matched server-side events typically achieve. Savings figures are calculated against current Shopify App Store pricing, checked regularly. Conversion-recovery percentages (20–40%) match published ranges from Meta's own CAPI documentation. No fabricated metrics. No purchased reviews. No manufactured social proof. If a number isn't backed by a source, it isn't here.
What I work with directly
The guides on this site cover areas I implement hands-on. Here is an honest breakdown of what I build and test directly:
