“Janice, are we selling poison on the website?”
“Gift” means poison in German. Your store has been selling it for 3 months. Cassian™ would have caught it on day one.

Is your store OK?
Other tools scan your website. Cassian™ knows your store. Broken links, translation errors, mismatched product data — we find what you didn't know was broken.

The problems you don't know you have
You're losing customers right now. You just don't know it yet.
Every day, store owners discover issues that have been costing them sales for weeks — sometimes months. Here's what Cassian™ finds within minutes.
Your moisturiser is called "Morning Mist." Your German customers read "Morning Manure."
Machine translation doesn't understand context. Your best-selling skincare product might be telling international customers something revolting.
That product page gets 2,000 visits a month from Germany. Every visitor who reads "Mist" sees "Manure."
Your top product page has been 404ing for 3 weeks. Nobody told you.
You deleted an old collection but the link is still in your navigation, your email footer, and 14 product descriptions.
That page was getting 800 visits a month. At a 3% conversion rate, that's 24 lost orders you'll never see.
Your admin says "In Stock." Your storefront says "Sold Out."
Your Shopify admin and your live storefront are telling different stories. No scraper can find this — because scrapers can't see your backend.
Cassian™ connects to your store and compares what you think you're selling with what customers actually see. This is what no other tool can do.
12 of your product pages have the exact same meta description.
Copy-paste happens. But Google doesn't index duplicate content well, and your customers can't tell your products apart in search results.
Those 12 pages are competing against each other instead of ranking individually. That's 12x the organic traffic you're leaving on the table.
Is your store OK?
Cassian Sentinel™ · Order Pulse
“Site is up” doesn't mean “store is selling.”
A broken payment gateway. A misconfigured shipping zone. A checkout bug after a theme update. Your site stays up. Your store stops selling. You find out hours later.
Order Pulse monitors your checkout health every hour. It compares actual orders against your store's historical patterns and alerts you the moment something breaks — not when a customer complains.

“Cassian Sentinel™ detected 0 orders for 3 consecutive hours. Your store typically averages 4.2 orders per hour on Mondays at this time.”
This alert fires for all tiers — including free. Because if your checkout is broken, you need to know. Now.
Cassian Shield™
Your store deserves enterprise security.
Cross-site scripting. Clickjacking. Missing security headers. Exposed admin endpoints. The vulnerabilities that keep security teams up at night — and most store owners have never heard of.
Cassian Shield runs the same OWASP ZAP scanning used by Fortune 500 security teams. Automated. Continuous. Translated into plain English so you know exactly what matters and what to fix first.

Cassian Sentinel™ · Uptime
Your SSL expires in 22 days. Your domain expires in 9.Do you know that?
Uptime monitoring is table stakes. Cassian Sentinel goes further — it watches your SSL certificate expiry, your domain registration expiry, and your response times. The things you forget about until they take your store offline at 2am on a Saturday.
Checks every 1–5 minutes. Confirms before alerting. No false alarms. When Cassian Sentinel says your store is down, it's down — and you know within minutes, not hours.

“The domain registration for mystore.com expires in 9 days (6 March 2026). If it lapses, your entire store goes offline — and someone else could register it. Renew now.”
Cassian Sentinel checks your domain registration and SSL certificate on every health check. You get 30 days' warning — not a 2am surprise.
Most stores are doing better than they think.
Here's the thing — every audit tool leads with problems found. Cassian™ leads with confidence given. Your first scan will probably tell you your store is in good shape. And if it finds something worth fixing, you'll be glad you checked.
Status before issues. Confidence before action. Always.

Cassian™ Weekly Digest
Monday 8:00 AM (UTC) · cassian@getcassian.com
Your Cassian Score™: 84 (+3)
Up from 81 last week. Nice work.
3 things worth your attention
/products/summer-dress-2024 links to a deleted collection. This page gets 340 visits/week.
3 product descriptions on /fr/ have machine translation artifacts that read unnaturally.
5 product images uploaded this week have no alt text. Quick fix — 2 minutes.
Your store is in good shape. We're watching. You get back to it.
Weekly digest
Monday 8am (UTC). Plain English. Three things.
No dashboards to check. No jargon to decode. Every Monday, Cassian™ sends you a short email with your score, what changed, and exactly what to do about it.
If everything is fine, we'll tell you that too. Permission to stop worrying.

Built for busy founders
You don't know what you don't know.
Running a Shopify store is a full-time job. Cassian™ is the colleague who watches everything you can't.

You're too busy to check
You're managing inventory, running ads, answering support tickets, and shipping orders. Checking every page on your site for broken links and bad translations? It's not happening. Cassian™ does it for you, every single day.
You can't see what customers see
Your Shopify admin shows you one thing. Your storefront might show something completely different. Different prices, different descriptions, different stock levels. You'd never know unless a customer complains — or leaves.
You sell internationally but can't read every language
You've translated your store into French, German, Spanish. But did the translator catch every nuance? Is that product description accidentally offensive? You can't check — but Cassian™ can.
SEO tools overwhelm you with jargon
"Canonicalization error on paginated collection template." What does that even mean? Cassian™ tells you in plain English: "Your summer collection page isn't showing up in Google. Here's the fix."
Every lost customer costs more than you think
A broken link isn't just annoying — it's revenue you'll never recover. A mistranslation isn't just embarrassing — it destroys trust. The cost of not knowing is invisible until Cassian™ makes it visible.
You want permission to stop worrying
That's really what this is about. You want to know your store is OK — and if it's not, you want someone to tell you exactly what to fix. That's Cassian™. Peace of mind, delivered every Monday at 8am (UTC).
AI search readiness
Is your store visible to AI?
ChatGPT, Perplexity, Google AI Shopping — they're already recommending products to buyers. But they can only recommend stores with the right structured data.
Fewer than 1 in 4 Shopify stores have sufficient structured data for AI shopping assistant citations. Most store owners don't even know this matters yet. Cassian™ checks your AI readiness in every scan.
Your AI Search Readiness
AI Readiness: Medium
Your store is partially visible to AI shopping assistants. Adding llms.txt and completing your structured data would significantly improve discoverability.
