Your Shopify Apps Are Killing Your Speed Score
The average Shopify store runs 15-20 apps. Each one injects JavaScript that slows your pages, tanks your Google ranking, and bleeds revenue. Thunder finds the worst offenders and neutralizes them — automatically.

Every App You Install Has a Hidden Cost
"You wouldn't leave 20 browser tabs open on your laptop. So why let 20 apps run scripts on every page of your store?"
Three Steps to a Faster Store
1. Diagnose
Thunder scans every script running on your store and shows you exactly which apps are dragging your speed down. Not PageSpeed guesswork — real, app-level data.
2. Optimize
One click. Thunder defers non-critical scripts, optimizes loading order, compresses images, and lazy loads below-the-fold content. Most stores see a 20-40 point improvement in under 60 seconds.
3. Monitor & Protect
Here's what makes Thunder different: it doesn't optimize once and walk away. Thunder continuously monitors your Core Web Vitals and automatically re-optimizes when something changes — a new app, a theme update, a traffic spike.
Speed Optimization Isn't a One-Time Fix
Your store changes constantly. New apps, theme updates, seasonal campaigns. Without active monitoring, your speed degrades silently — and you lose sales without knowing why.
Without Monitoring
With Thunder
Thunder watches your store 24/7 so you don't have to.
Speed Is Not a Vanity Metric. It's Revenue.
Faster Pages
Stores using Thunder load 2-4x faster on average
Higher Google Rankings
Core Web Vitals are a Google ranking factor. Pass them, rank higher.
More Revenue
Every 100ms faster = 8.4% more conversions (Google/Deloitte 2020)
Everything You Need to Stay Fast
Third-Party Script Control
Identifies app scripts hogging resources and defers them intelligently. The #1 cause of slow Shopify stores, handled automatically.
Smart Image Optimization
Automatic compression, lazy loading, and proper sizing. No manual work, no quality loss.
Core Web Vitals Dashboard
LCP, CLS, and INP tracked in real time inside your Shopify admin. Know exactly where you stand.
Automatic Re-optimization
When your speed drops — a new app, a theme update — Thunder detects it and re-optimizes without you lifting a finger.
One-Click Setup
No code changes, no theme editing, no developer needed. Install, click optimize, done. 60 seconds.
Safe & Reversible
Thunder never modifies your theme files. All optimizations apply at the network level. Turn off anytime, zero risk.
Trusted by 20,000+ Shopify Stores
"Our PageSpeed score went from 34 to 78 after installing Thunder. The third-party app scanner was a game-changer — we had no idea Klaviyo was adding 1.8s to our load time."
"Tried Booster and Hyperspeed before Thunder. Neither fixed our actual problem — too many app scripts. Thunder identified the issue in seconds and fixed it automatically."
"Finally an app that tells you WHY your store is slow, not just tries to slap a bandaid on it. Core Web Vitals monitoring in the dashboard is incredibly useful."
