The narrative says the web is going modern. The data says it hasn't happened yet. Across 10 million sites scanned by WebPulse, modern frameworks — Next.js, Nuxt, Astro, SvelteKit, Remix, Hugo, Eleventy — account for 17.5% of detections. Legacy frameworks hold 82.5%.
The 82.5% Reality
Where Modern Is Winning
The 17.5% average masks wide variation. In fintech, modern adoption reaches nearly 100% among detected sites. In government, it's below 5%. The migration isn't slow everywhere — it's fast in competitive industries and nearly absent in regulated ones.
The Opportunity
An 82.5% legacy base isn't a crisis — it's a market. Every percentage point of migration represents hundreds of thousands of sites. For agencies, consultancies, and platform providers, the addressable migration market at this scale is measured in billions.
