Turn Subtle Edits Into High-Ticket Agency Deals

Standard page checkers look for text noise. NotifyOnChange tracks architectural intent — structural signals that map directly to brand growth and validation budgets.

01

Shopify Theme Mutations

When a target store drops standard default themes (like Dawn) for premium architectures (Prestige, Impulse), it signals newly released optimization budgets or agency contract turnovers. Catch the transition instantly.

02

App Stack Audits

Track when a client's core competitor launches subscription apps, upsell bundles, or loyalty tools (Recharge, Klaviyo, Judge.me). Deliver proactive optimization plans to your clients the morning it happens.

03

Similarity Discovery Graph

Move beyond simple tech scanning. Input any storefront to map its entire competitive ecosystem. Instantly unlock identical brands filtered by theme choices, catalog velocity, and technology footprints.

CLIENT-SIDE ACCURACY VIA EXTENSION

The Cloudflare Problem. Solved via Symbiotic Architecture.

Most enterprise Shopify setups leverage intense script screening and anti-bot filters. Automated cloud scanners get blocked or cost a fortune in proxy rotations. We blend local browser observation with persistent server tracking.

✕ Standard Server Crawling

Reads baseline HTML strings, misses live script injections, risks permanent hosting IP bans, and fails to capture deep client-side application events safely.

✓ Distributed Browser Nodes

Our free browser extension captures live theme variables, active JS assets, and specific app scripts cleanly directly inside the active viewport session. Secure, ad-free, completely native.
