Engineering Architecture
Why Kutor Labs Extensions Are Built Differently
Legacy scrapers frequently suffer from heavy background CPU consumption, injected tracking pixels, or broken parsing across non-US Amazon regions. We built our extension factory around strict engineering rules:
100% Local-First & Zero Telemetry
Your search terms, product ASIN lists, and research queries never leave your browser. We maintain no remote databases or tracking pixels.
Manifest V3 Zero-Latency Execution
Engineered with asynchronous DOM MutationObservers and ephemeral service workers that terminate cleanly without draining battery.
Universal Multi-Locale Support
Built-in parsers seamlessly handle European comma decimals (€29,99), Asian currencies (¥3,500), and localized rating/delivery strings across 15+ marketplaces.
Instant Transparent Licensing
Powered by Dodo Payments for instant key fulfillment, generous free starter quotas, and one-time lifetime Pro ownership without recurring traps.
