Bloodhound monitors your Shopify store in real time. It catches every JavaScript error, times every third-party script, and puts a price on every issue — so you fix what matters first.
Broken add-to-cart. Payment widget crashing. Third-party app throwing exceptions on every page load. None of it visible. All of it expensive.
Deloitte found that a 100ms speed improvement increases retail conversions by 8.4% and AOV by 9.2%. Google found that as load time goes from 1s to 3s, bounce rate increases by 32%. These aren't edge cases. They're your store, right now.
And that's just performance. Then there are the silent errors — the broken add-to-cart on mobile Safari, the payment widget crashing on slow connections, the third-party app throwing exceptions on every single page load. None of it visible in Shopify Analytics. You see conversion rate dip. You don't know why.
A 100ms speed improvement increases retail conversion rates by 8.4%
53% of mobile visitors abandon a page that takes longer than 3 seconds to load
Sites that load within 5 seconds see 70% longer average sessions and 35% lower bounce rates
Every 100ms of added latency costs 1% in sales, per Amazon's internal testing
Third-party requests account for 45% of all requests on median web pages, with significant CPU impact
The average Shopify store runs 15–25 third-party scripts. Each one is a risk you can't see coming. Bloodhound names them, times them, and tells you which ones to kill.
Under 5KB gzipped. Deferred. Non-blocking. Install once and see everything — every page, every visitor, every script.
Bloodhound catches every JavaScript error, promise rejection, and failed network request — including console.error calls. Groups them into issues with stack traces, affected session counts, and revenue at risk. Console.warn capture on Pro.
All five metrics from real visitor traffic. p75 scoring against Google's thresholds with 30-day trend charts — so you see regressions before they compound.
Every JavaScript file on your storefront, ranked by damage. Blocking time, transfer size, origin. Find the app that's costing you 800ms of LCP and kill it.
Every issue gets a price tag. Affected sessions × your conversion rate × your AOV. Fix the most expensive bug first. Stop guessing what matters.
Bloodhound groups errors into issues and tracks them from new to resolved. Auto-regression detection fires the moment a fixed bug returns — before a customer tells you.
Shopify locks checkout off to every app. We use the Web Pixel to get inside anyway. Cart add, checkout start, payment submit, purchase — full funnel where every other tool stops.
Bloodhound pushes new issues and regressions to Slack, Teams, Discord, or any webhook. Configurable cooldown so you're informed, not spammed. Minutes, not days.
Error trackers are everywhere. None of them audit your supply chain. Every Bloodhound install runs a weekly security scan of your storefront — automatically.
Scans your scripts weekly for exposed API keys — Shopify, Klaviyo, AWS, GitHub, Stripe. If one leaks, you'll know before anyone exploits it.
Flags outdated jQuery, Handlebars, Lodash, AngularJS, Bootstrap on your storefront with published CVEs. Exactly which file, exactly which version.
Weekly scan of your security response headers (CSP, HSTS, X-Frame-Options, Permissions-Policy) scored 0-100 with specific remediations. Live-captures CSP violations and mixed-content loads from real traffic.
Define which script origins you trust. Any new one loading on your storefront is flagged immediately — early warning for Magecart-style injection attacks.
Ranks the third-party apps on your storefront by main-thread blocking time. Named recognition for Klaviyo, Hotjar, Yotpo, Tidio, Intercom and 40+ more — plus uninstall guidance for the worst offenders.
Rotate-able bearer tokens scoped to your store. Full programmatic access to issues, CWV, scripts, and security findings for your own pipelines.
Live data from your Shopify storefront. Errors, performance, scripts, alerts — all inside the admin you already use.
