“Game changer for peace of mind.”
Now available for Shopify!
Imagine if your Shopify store could tell you when something’s wrong.
Cassian™ tells you the moment something breaks. A free scan shows what’s already wrong.
Cassian is now available on the Shopify App Store. Be one of the first Shopify merchants to try it and help shape what comes next. Get in touch.
Only the alerts that matter.
Cassian™ messages you when something needs your attention — and stays quiet until then.
Example alerts from one week: orders stopping, the store going down, a price changing on its own, and a Sunday all-clear review.
Cassian™ does two things.
Watch
The moment something breaks.
So you can stop watching your phone.
- Orders stop or slump
- Store goes down
- Prices change on their own
- Stock about to run out
- SSL or domain about to expire
A check every 5 minutes.
Every minute on Prime. Around the clock, from the day you connect.
You pick the channels and set the thresholds.
Find
What’s quietly wrong.
The slow leaks that never set off an alarm.
- Broken links and dead redirects
- Missing or invalid structured data
- Translation errors
- SEO and GEO (AI search) gaps
- Security headers
Your store is in great shape.
45+ capability checks, every scan.
Every finding rolls up into one number, so you can see the whole store at a glance — and watch it move as you fix things.
No card. First findings in seconds.
Works with your store, wherever it runs
Including Shopify Plus stores. Magento and Medusa are next.
From store owners
Less checking. More knowing.
“It flagged a problem on a product page and I fixed it from my phone. Happy Days.”
“Setup = easy. A couple of the suggestions weren’t fully relevant to our store, but the broken links it found were real and I’d missed them.”
“I mostly wanted to know if orders suddenly went quiet. Now I get a message instead of opening site ten times a day.”

Stores are complicated. Things slip.
You're on a great platform — but stuff still happens. Wrong prices, broken links, bad translations, pages that went live too early. You should hear about it from Cassian™, not from your customers.
Where’d the orders go?
A shipping rule changes. Your biggest market quietly can’t check out.
Cassian™ watches your order patterns and lets you know when something’s off — from every few hours to hourly, depending on your plan.
$99.90 just became $9.99.
A bulk update, a decimal slip, a typo. You just sold 200 units of your best seller for 90% off.
Cassian™ monitors every product price via your platform API and alerts you when something changes.
That wasn’t supposed to go live yet.
A sale page goes live early. A draft product becomes visible. Something changes that shouldn’t have.
Cassian™ tracks every page on your site and tells you when things change.
Your domain just expired.
Your domain registration quietly lapses. Your store vanishes. Customers shop elsewhere. Someone else registers it.
Cassian™ tracks both and lets you know weeks before it matters.
Click. 404. Gone.
A product link breaks. An image stops loading. Nobody mentions it.
Cassian™ checks every link and image on your site — automatically, on schedule.
Down since 2am. Nobody noticed.
Your store goes offline overnight. You find out from a customer DM seven hours later.
Cassian™ pings your store every few minutes. You’ll know before your customers do.
Lost in translation.
Your moisturiser is called “Morning Mist.” Your German customers read “Morning Manure.”
Cassian™ reads every translated page the way a native speaker would — not spell-check, real context.
“Found s**t I didn't even know needed fixing!”
Every Friday I’d leave the office wondering if I needed to watch the site over the weekend in case something broke. Anxiety inducing and always in the back of my mind. I don’t worry about that anymore. Game changer for weekends.
