The Invisible Infrastructure Cost
WebPulse detected 7,427,780 WordPress sites in a scan of 10 million domains. The average WordPress site runs 20-30 plugins. That's approximately 150-220 million plugin installations across the detected WordPress web. Each plugin is an independent codebase with its own update cycle, security vulnerabilities, and compatibility requirements. The cost of maintaining this plugin ecosystem — across every organization that runs WordPress — exceeds what most people imagine.
The Per-Site Math
A single WordPress site with 25 plugins requires approximately: 2-4 hours/month for plugin updates and compatibility testing. 1-2 hours/month for security patch evaluation. 4-8 hours/year for major WordPress core updates that break plugin compatibility. At a conservative $75/hour for technical maintenance, that's $3,600-$6,000/year per site in plugin maintenance alone — before hosting, content, or design.
The Aggregate Number
Multiply per-site maintenance costs across 7.4 million detected sites. Even at the conservative end — $3,600/year × 7.4 million sites — the global cost of WordPress plugin maintenance is approximately $26.6 billion per year. Not all of this is paid labor — much of it is volunteer time, IT staff handling updates as a side task, or sites simply not being maintained (which creates its own security costs). But the economic activity consumed by plugin maintenance is enormous.
Modern frameworks eliminate this category entirely. Astro, Hugo, and Eleventy have zero plugins to maintain. Next.js and SvelteKit use npm packages that are version-locked and don't auto-update. The $3,600-6,000/year per site in plugin maintenance drops to approximately $0.
