ENGINEERING ARCHITECTURE BRIEFING

Why We Don't Build on
Legacy WordPress or Page Builders.

An executive technical breakdown of why modern high-ticket businesses are migrating away from bloated PHP plugins to sub-second Next.js edge funnels.

Over 90% of all web application security breaches originate in outdated third-party CMS plugins.

Feature-By-Feature Breakdown

See how modern headless web architecture compares to 2010s CMS platforms.

Feature / Metric	Traditional WordPress	LeadScrub Next.js
Server Architecture	Legacy PHP 7.4/8.x on shared Apache/Nginx running heavy MySQL queries per visitor	Serverless Next.js edge runtime with global CDN edge caching (Vercel/Cloudflare)
Vulnerability Attack Surface	Average 25–40 third-party plugins with frequent zero-day PHP/SQL injection exploits	Zero WordPress plugin stack. Static edge rendering leaves no direct database exploit vector
Mobile Time-To-First-Byte (TTFB)	1,200ms – 4,800ms (database query latency + dynamic theme parsing)	38ms – 95ms globally distributed edge response
Inbound Spam Prevention	Default open contact form plugins (Contact Form 7/WPForms) flooded with bot spam	Built-in multi-stage scrub pipeline (MX check, honeypot traps, AI qualification)
Annual Maintenance Cost	£1,200 – £3,600/year in agency retainers just to patch breaking plugin updates	Optional £200/mo or 100% self-hosted freedom (zero mandatory retainers)
Code & Data Ownership	Often locked to agency hosting servers with proprietary theme licenses	100% GitHub repository & database ownership transferred to you
Page Builders (Wix / Squarespace)	Locked proprietary walled garden: cannot export production code, cannot self-host, locked to £25–£50/mo platform fees	Complete Next.js React code ownership: exportable, hostable anywhere (Vercel, AWS, VPS, Pi) with 0 vendor lock-in
