Sub-0.3s Page Speed
By serving pre-rendered static HTML via Next.js SSG or SSR on Vercel/Netlify edge networks, your site renders instantly anywhere in the world.
Immune To Database Attacks
Because the public website is decoupled from the WordPress database, hackers cannot target traditional SQL injection or wp-admin entry points.
