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 $225–$1,250/month and Triple Whale charges $149/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 $145–$650/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.
Featured in. Stack Architect was featured in eCommerce Manager's Top Shopify Apps for Automating Your Store (July 2026), where the free automation stack is recommended alongside the paid tools it replaces. I was also interviewed by CTO Sync on deciding when engineering teams should pay down technical debt — the same prioritisation thinking that shapes how the tools and guides here are built and maintained.
Open-source & community. Stack Architect tools are listed in Awesome No-Code / Low-Code and Awesome Cloudflare, and the attribution-gap benchmark runs on an open-source Cloudflare Workers backend.
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:
I ship products, not just guides
The clearest test of whether someone understands Shopify inventory is whether they can build for it. StockLog is my Shopify app — a persistent stock ledger that decrements on orders, restocks on cancellations and refunds, imports Stocky CSV exports ahead of the 31 August 2026 shutdown, and keeps a timestamped audit trail of every movement. It launches on the Shopify App Store in August 2026 at $7.99/month.
The live product at stocklog.onrender.com — every inventory guide on this site is informed by building it.
