While legacy portals burn in Google's Core Web Vitals inferno, a new generation of real estate platforms is emerging from the ashes. These aren't incremental improvements — they're architectural revolutions that make 18-month migrations look like medieval siege warfare against jets.
The "Armor Stack" isn't theoretical. It's battle-tested technology serving billions of requests daily across industries that demand millisecond response times: fintech, gaming, and e-commerce. Real estate is simply the latest — and most lucrative — conquest.

The Final Play
The massacre isn't coming — it's scheduled for August 1st, 2025. Legacy portals will lose 40% of their traffic overnight. Their agents will hemorrhage leads. Their valuations will crater.
But disruption creates opportunity. The Armor Stack isn't just a technical solution; it's a business model that turns extinction events into gold rushes.
