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.

Shopify Robots.txt + AI Crawler Checker

Paste your robots.txt contents and instantly see which crawlers are allowed or blocked: Googlebot, GPTBot, ClaudeBot, PerplexityBot, Google-Extended, and 6 more. Checks Shopify-specific patterns including /policies/ disallow and missing Sitemap directives. 100% browser-side, no signup, no network calls.

  • AI crawlers silently blocked from training and citation, costing you organic brand mentions in ChatGPT, Perplexity, and Gemini answers
  • Googlebot or Bingbot blocked from key paths like /products/ or /collections/, hiding your catalog from search index
  • Missing Sitemap directive in robots.txt, leaving crawlers without a map to your most important pages
  • /policies/ disallow that ships with some Shopify setups flagged so you know whether it is intentional

Shopify Product Schema Validator

Paste your Shopify product page HTML or raw JSON-LD and validate it against the 4 Product schema errors that block AI citation: missing GTIN/brand/MPN, broken AggregateRating, malformed Offer priceCurrency/availability, and BreadcrumbList missing position integers. 100% browser-side, no signup, no network calls.

  • Missing GTIN, brand, or MPN that prevent AI agents from matching your SKU across competing storefronts
  • AggregateRating emitted without a valid itemReviewed reference, disqualifying the product from review-weighted recommendations
  • Offer with malformed priceCurrency (not ISO 4217) or non-standard availability enum, dropping the product from price-comparison flows
  • BreadcrumbList missing integer position values or malformed itemListElement, isolating the product from category-level agent queries

What's coming next

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

  • Shopify Plan ROI Calculator

    Input monthly revenue, order count, and feature needs (B2B, Markets, custom checkout). Output the right plan (Basic, Shopify, Advanced, Plus) and the 12-month cost vs benefit of upgrading.

  • App Stack Cost Calculator

    Paste a store URL, get the installed app stack with typical monthly cost per app, annual total, and a ranked list of which ones replace cleanly with native Liquid. Pairs with the App Bloat Index.

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.
