Everything that catches storefront problems before they cost sales.

⚠ Real-user error tracking

StorePulse's Theme App Embed installs a tiny script (~6 KB gzipped) on your storefront that captures JavaScript errors, unhandled promise rejections, and resource load failures from real visitors. Errors are grouped by stack signature into issue groups, so you see "this error happened 1,200 times across 8 pages" instead of 1,200 separate noise rows.

• Captures error message, stack trace, page URL, page type, session ID, and metadata.
• Groups by stable fingerprint so re-occurrences increment a counter, not a new row.
• Filters out StorePulse's own internal events so you don't see us in your own data.
• Per-issue trend chart and "first/last seen" timestamps.

🤖 Claude-powered AI fixes

For every error group, you can request an AI fix proposal. We send the error message, stack trace, and recent occurrences to Claude (Anthropic) and get back a structured fix:

• Why it broke — root cause in plain English.
• Theme file — exact path to open.
• Code to find — the broken snippet.
• Code to replace it with — the safe replacement.
• How to verify — what to test after applying the fix.

AI fixes consume credits from your monthly plan allowance. The proposal is a recommendation — you review and apply manually.

⚡ Core Web Vitals

Real-user performance metrics — the same numbers Google uses for ranking. Measured on actual visitors, not synthetic lab tests.

• LCP (Largest Contentful Paint) — perceived load speed.
• CLS (Cumulative Layout Shift) — visual stability.
• INP (Interaction to Next Paint) — responsiveness.
• FCP (First Contentful Paint) — first render.
• TTFB (Time to First Byte) — server speed.

Per-page breakdowns flag the URLs that are dragging down your scores. Each metric is rated good / needs-improvement / poor based on Google's published thresholds.

🛒 Synthetic checkout monitor (Pro+)

Every n minutes (configurable), our Cloudflare Browser worker drives a real browser through your storefront: loads home, picks a test product, adds to cart, opens checkout. If any step fails, you get an immediate Checkout broken alert with the failed step, error message, and timing.

This is the difference between finding out checkout is broken from your monitoring and finding out from an angry customer email three hours later.

📡 Uptime monitoring

Every 5 minutes, StorePulse pings your storefront's home page, top collections, cart page, and policy pages. Each check measures status code and response time. Failures fire an immediate Storefront offline alert.

Slow-but-up degradation also surfaces — if your home page suddenly takes 8 seconds to respond, that shows up before a hard outage.

🔍 SEO Monitor

Every 6 hours, StorePulse scans high-traffic URLs (home, top collections, cart, policy pages) for on-page SEO issues:

• Broken outbound and internal links (HTTP 4xx / 5xx).
• Missing or duplicate <title> and <meta description>.
• Canonical conflicts.
• Missing structured data on product pages.
• Image alt-text gaps that hurt accessibility and image search.

🎨 AI Theme Review (Starter+)

One-shot deep audit of your theme code paired with a runtime accessibility scan. Three tiers — Quick (30 files / 25 credits), Standard (80 files / 75 credits), Deep (150 files / 150 credits) — let you scope cost to depth.

The reviewer flags:

• Hard-coded API keys, tokens, or secrets in theme files.
• Broken cart / checkout / Add-to-Cart flows.
• Performance bottlenecks (unminified JS, render-blocking assets, oversized hero images).
• SEO issues (heading hierarchy, missing schema, canonical bugs).
• Best-practice violations specific to Liquid and Shopify Section/Block patterns.

Each finding has severity, file path, line number, code snippet, plain-English explanation, and recommended replacement code. Reviews can be cancelled mid-run with no credit charge.

♿ Accessibility Scanner

WCAG 2.2 AA compliance auditing built on axe-core (the same engine Google's Lighthouse uses). Scans run in real Chromium browsers via Cloudflare Browser Rendering, so they catch issues that static analyzers miss.

• Storefront audit — up to 50 pages diversified across home, cart, search, top products, top collections, static pages, policies, and account flows.
• Group of pages — focus a scan on Product pages, Collection pages, static Pages, or other paths (search, policies, cart).
• Specific page — paste any URL on your storefront. Available on Free plan.
• Per-finding remediation guidance with WCAG criterion linked to W3C's official "Understanding" pages.
• Lawsuit-risk scoring (High / Medium / Low) based on accessibility score and severity counts — mirrors how ADA / EAA / AODA / BFSG plaintiffs screen targets.
• Schedule daily or weekly scans on paid plans.

🔔 Smart alerts

StorePulse emails alerts when something matters — not for every ping. Configurable rules per merchant:

• Error spike — too many new error groups within a window.
• Storefront offline — any uptime check fails.
• Checkout broken — synthetic checkout walk fails twice in a row.
• Refund spike — refund count exceeds threshold.
• Inventory zero — a tracked variant hits zero stock.

Send to up to 3 email addresses per store. New-issue alerts dedupe per fingerprint, so you get one email per unique error, not one per occurrence. Per-rule cooldowns prevent inbox flooding.
