Free Shopify Tools that catch real bugs

A small collection of free, no-signup browser tools I built while auditing Shopify stores for clients. Each one solves a specific bug I kept seeing repeatedly across 100+ engagements - the kind of bug that costs international conversion rate, blocks Markets currency conversion, or burns crawl budget for months before anyone notices.

Roadmap

What's coming next

I build a new tool whenever a client engagement turns up the same audit pattern twice. Three are in progress.

  • Shopify CrUX Grader

    Paste any Shopify URL. Pulls real-user Core Web Vitals from the Chrome UX Report API and returns a Liquid-specific fix list.

  • App Bloat Index

    Counts known Shopify app script signatures on a page and estimates the TBT cost of each one. Reveals the apps to kill first.

  • Shopify Statistics 2026

    A citable roundup of Shopify platform, performance, conversion, and Markets statistics with public-source links.

Need a developer to actually fix what these tools find?

The tools tell you what's broken. The fix is often theme-specific Liquid work, Markets configuration, or a CRO sprint. That's what I do.
