The Web Is Moving Beyond the Old CMS Era

WordPress is not dead. It is not even small. But the direction of travel matters, and the direction is no longer automatic growth.

Search Engine Journal recently reported that WordPress has declined for six consecutive months in W3Techs market-share data. The numbers are still enormous, but the movement is worth taking seriously: WordPress fell from 43.20% in December 2025 to 41.90% on May 27, 2026.

A 1.3 percentage-point drop may sound small until you remember what it measures. WordPress powers a huge portion of the public web. When a platform at that scale starts moving down for half a year, it is not just a platform story. It is a signal about how website building itself is changing.

The PHP Problem

My take is simple: WordPress is based on PHP, and PHP as a programming language has been in a long decline of developer attention.

PHP still runs a massive amount of production software. It has mature frameworks, hosting support, documentation, and a large installed base. But momentum is different from installed base. New developers, new startups, and new AI-era workflows are often centered around JavaScript, TypeScript, Python, Rust, Go, and modern full-stack frameworks.

TIOBE's May 2026 index gives a useful snapshot. PHP ranked #14 with a 1.15% rating, down slightly year over year. TIOBE is not a perfect measure of language value, and it should not be treated as a law of nature. But as an indicator of mindshare, it supports what many developers already feel: PHP is no longer one of the obvious default languages for new web work.

CMS Convenience Is Being Unbundled

WordPress won because it made website publishing practical. A business owner could edit pages, install plugins, change themes, add forms, publish blog posts, and manage SEO without hiring a developer for every small change.

That was a very strong value proposition for a long time. But agentic coding tools are starting to unbundle it.

A capable AI coding agent can now build pages, update layouts, refactor components, add forms, connect APIs, generate content structures, and push changes through a modern development workflow. The business owner does not necessarily need a traditional CMS dashboard if the website itself can be changed quickly through natural-language requests and reviewed like software.

This does not mean every website should abandon WordPress. For many organizations, WordPress remains practical. It is familiar, inexpensive to host, and supported by a large ecosystem. But the old reason for choosing it, "we need a CMS because changing a website requires too much developer time," is becoming weaker.

The New Website Stack

Modern websites increasingly look less like a pile of plugins and more like software products. They use frameworks such as Next.js, Astro, and other component-based systems. Content can live in Markdown, a headless CMS, a database, Notion-like tools, or structured files. Deployment can be automated. Performance and security can be improved by reducing the number of moving parts.

The important change is not just technical. It is operational. In the old model, a small business often chose WordPress because it could not afford custom software. In the new model, AI lowers the cost of custom software. That makes a tailored website or web app more realistic for businesses that previously had to settle for a generic theme and a stack of plugins.

Agentic coding also changes maintenance. Instead of waiting for plugin updates, worrying about compatibility, or paying someone to click through admin screens, a business can ask for specific improvements: make this landing page faster, add a customer intake form, rewrite this section for AI search, connect this to our CRM, or generate a new service page from our notes.

What This Means For Small Businesses

The practical lesson is not "never use WordPress." The practical lesson is: do not choose WordPress by reflex.

If you need a simple blog and already have a trusted WordPress workflow, it may still be fine. If you rely on a specific plugin ecosystem, it may still be the right tool. But if you are building a growth-focused website in 2026, you should ask a better question: what website architecture will help us move faster over the next three years?

For many businesses, the answer may be a lighter, faster, AI-assisted site built with modern web technology. That kind of site can be easier to optimize for search, easier to connect with AI tools, easier to secure, and easier to evolve into a real application when the business grows.

My View

WordPress is still important, and it deserves respect. It helped millions of people publish on the web. But platforms decline first in mindshare, then in recommendations, then in market share.

The PHP trend is one warning sign. The rise of modern JavaScript frameworks is another. The biggest change, however, is agentic coding. Once AI can help build and maintain custom websites at a practical cost, the traditional CMS is no longer the obvious center of the web.

The future is not simply WordPress versus another CMS. The future is CMS versus AI-assisted software creation. That is a much bigger shift.
