For years, the standard answer to "what do we build the website with?" was almost automatically: WordPress. No surprise – the content management system is established, flexible and to this day powers a very large share of the web. So it would be dishonest to claim WordPress is dead. What is changing, though, is the reflex that every website has to run on WordPress.
Because AI now builds websites in a fundamentally different way: not as a CMS with theme, database and a stack of plugins, but as lean, precisely generated code. The result is often faster, lower-maintenance and secure "by default". That is exactly why the era is shifting – slowly, but clearly.
What changes in 2026 – with numbers
This shift is not a future scenario – it is happening right now. The way websites are created is measurably moving towards AI:
- Around half of front-end UI code is likely to be AI-generated by the end of 2026. The rough build of layouts and components is increasingly moving to the machine.
- Roughly 73% of designers and developers already use AI tools for layout and code – AI is no longer a niche tool but an everyday part of web craft.
- Clean, modern code out of the box: AI now produces structured code based on modern frameworks (e.g. React, Tailwind CSS) with optimised assets – instead of generic template bloat.
This has direct consequences for performance. Because AI-generated code is lean and does without the ballast of a full CMS, such a site achieves good Core Web Vitals from the start. In practice this means noticeably better load times and sometimes roughly twice as good LCP values (Largest Contentful Paint) – a factor that matters both for users and for rankings.
The WordPress problem: the ballast
WordPress is popular for good reasons – but its flexibility comes at a price. What began as a lean blogging system is now an extensive CMS that simply brings too much to many simple websites. The typical ballast:
- Bloated structure: theme, page builder, database queries and many layers create overhead that slows the site down.
- Plugin chaos: a plugin for every feature – quickly it's dozens that influence each other and become hard to maintain as a whole.
- Constant updates: core, theme and plugins need regular updating. If that lapses, the site ages technically and becomes vulnerable.
- Security gaps – especially via plugins: a large share of WordPress security issues comes not from the core but from third-party extensions.
- Maintenance effort: backups, compatibility tests and troubleshooting after updates cost time continuously – or money if you outsource them.
For large editorial teams and complex portals this effort is justified. For a lean company website that mainly needs to load fast and work reliably, it is often hard to justify.
The AI way: lean code instead of CMS overhead
The AI approach flips the logic. Instead of assembling a website from a large system, exactly the code the site needs is generated – and no more. That brings a set of benefits that follow directly from dropping the ballast:
- Faster: less code, optimised assets, no heavyweight database queries – good Core Web Vitals are the default state, not the goal after months of optimisation.
- Low-maintenance: there is no plugin zoo that constantly needs patching. Static or leanly generated code simply has fewer moving parts.
- Secure "by default": where dozens of third-party plugins don't run, there is far less attack surface.
- On-brand: the design isn't bound to a theme corset but tailored exactly to the brand.
A good example is this website itself: built lean, fast and without CMS overhead – conceived and implemented with AI support. So what you see here is not just theory, but the approach in practice.
Honest: when WordPress still makes sense
An honest article has to show the other side too. WordPress has good reasons for its reach – and in certain constellations it remains the right choice:
- Huge plugin ecosystem: for very specific features – shop, community, membership areas, booking systems – there are ready-made, proven extensions.
- Very large content scaling: editorial teams with many authors, thousands of posts and editorial workflows benefit from the mature CMS core.
- Existing WordPress teams: where know-how, processes and extensions are already established, there is no need to reinvent the wheel.
The AI approach, by contrast, shines where speed, low maintenance and performance count: for SMB websites, marketing sites, landing pages and relaunches. These projects make up a large part of everyday web work – and benefit most from doing without CMS ballast.
Just as important is an honest expectation: AI delivers the solid rough build, the human polish stays decisive. Pure "vibe coding" – just generating away and hoping – is not enough for everything. Strategy, structure, brand, accessibility and quality assurance remain human tasks. The division of labour works best: AI builds fast and clean, humans steer concept and quality.
How we work at Grünberg.Digital.
We see AI not as a replacement for craft, but as an accelerator. Concretely that means: we build AI-supported, lean and high-performance websites – from strategy through implementation to operation, from a single source.
- Strategy: we first clarify what the project really needs – and whether a lean AI approach or a CMS like WordPress is the more suitable basis.
- Implementation: AI takes on the fast, clean rough build; we handle concept, design, structure and the polish that truly makes a site good.
- Operation: because there are fewer moving parts, the ongoing effort stays low – more focus on content and growth instead of updates and troubleshooting.
The result is websites that load fast, need little maintenance and still pay into the brand individually – without the overhead that makes many classic projects sluggish.
Conclusion: the era is shifting
WordPress isn't finished – it still powers a large share of the web and remains strong for editorial teams and complex portals. What ends is the assumption that every website has to run on it. For many company sites, marketing sites and landing pages, AI-generated lean code is faster, lower-maintenance and more secure today. The era is shifting – towards websites that are lighter to build from the ground up.
