Sign up
Optional but recommended. Takes 30 seconds.
Click “Connect Shopify” in your settings and authorise read-only access. Cassian connects via the GraphQL Admin API — the same API Shopify recommends for all new apps. Without the connector, Cassian still works by crawling your storefront. With it, you unlock backend vs frontend checks, metafield access, and translation completeness analysis.

40+ checks. Zero effort. You just watch.
The moment you add your store, Cassian™ begins crawling. It renders every page in a real headless browser, analyses content with AI, validates translations, checks schema markup, and tests platform consistency. Results stream in live as each page completes — most stores finish within a few minutes.
One number. Five layers. Complete clarity.
Your Cassian Score is a single number from 0 to 100 that tells you exactly how healthy your store is. It’s weighted across five categories: Technical Health (30%), Content Quality (25%), Translation Accuracy (20%), Platform Consistency (15%), and LLM Readiness (10%). Green means you’re in great shape. Amber means a few things to watch. Red means attention is needed — and we’ll tell you exactly where to start.
Cassian Score™
Your store is in great shape.
Every week, a digest. Every day, peace of mind.
Once your store is connected, Cassian runs scans on a schedule — daily for Protector and above, twice weekly for Analyst. Every Monday morning at 8am (UTC), you receive a plain-English digest: what changed, what improved, what needs attention. No dashboards to check. No reports to generate. Just clarity, delivered.

Under the hood
Every scan runs the same pipeline, whether it's your first or your five-hundredth. Here's what Cassian does with each page.
Cassian uses a managed headless browser to render every page with full JavaScript execution. We see your store exactly as your customers do — not a simplified HTML snapshot.
Each page’s content is analysed by Cassian AI™ for spelling, grammar, readability, and completeness. Translations are compared against source text with per-sentence accuracy scoring.
Schema markup is extracted and validated against Google’s requirements. Missing required fields, incorrect types, and incomplete Product schemas are flagged with specific remediation steps.
If you’ve connected Shopify, Cassian compares what’s in your admin (prices, descriptions, images, translations) against what’s rendered on the storefront. Mismatches are surfaced immediately.
Every scan captures a full-page screenshot, stored securely in Cloudflare R2. This builds a visual history of your store so you can see exactly when something changed — and what it looked like before.
All findings are weighted, categorised, and rolled into a single Cassian Score from 0 to 100. The score is designed to be stable, meaningful, and actionable — not a vanity metric.
Enter your store URL. We handle the rest. If everything is fine, we'll tell you. If it's not, you'll be glad you checked.
