Static site generators still beat LLM for one key reason: scalability

If you are new to the program, you can enjoy the powerful tools available in 2026 that help you skip all the footwork. But what if I told you that even though LLMs are amazing, they are not the best tools for developing a consistent website?

LLMs are not top-notch tools for most professions, and web development is no different. Each brand costs money, and they are somewhat of a gamble—results may vary. In comparison, static site generators (SSGs) are time-honored solutions that solve a very specific problem: scalability.

Basic differences

Fixed-field generators and LLMs are completely opposed to each other

SSG is a program that compiles a list of templates into multiple HTML files. Templates contain domain-specific syntax (such as curly braces), character types, and HTML—a combination of markup and code. Usually, you write your text content in some markup format (like Markdown), create your own templates, and SSG will compile your content into HTML. As a result, the results are very determined (predicted), there is no difference between the results except their content.

LLM is a combination of vectors, math, and a little magic. I totally get away with it, but I’m confident when I say they’re not picky. They are examples of human speech that predict the next sign numerically. Combining them with multiple conditions changes their output, which varies between responses.

This difference between deterministic and non-deterministic represents an obvious conflict. But which one do you choose for building a sustainable website, and why?

Scalability

LLMs will grow as the static web grows

If you are building a small landing page, a simple HTML document may be sufficient. Displaying data or generating data doesn’t require a lot of code reuse, but publishing content does. A typical blog can have hundreds of posts, and larger organizations, tens of thousands. Reusing code is one of the main lessons you learn as a programmer, which I think some (beginner) coders don’t understand. LLMs promote disposable code by making it very cheap to mass produce or simply forget about it. It is difficult to judge the correct result.

A customer may accept a simple landing page, and it may work for you, but it is not the most responsible choice. For example, they may wish to expand from a simple landing page to include business-specific content or to include additional contact/about pages. A small website can quickly grow to XNUMX pages, which presents a problem: what approach do you take? Do you have a vibe code for multiple individual pages, or are you looking for a more robust solution?

By scalable, I mean designing the system to handle increasing workloads. For example, take a new website you wrote for a client. It has twelve pages. The client then wishes to display a call to action on the other side of each page. Sure LLM can update all 12 pages, but what about the next change, or the change after that? Are you going to copy all your work 12 times from there until the website ceases to exist?

A website can also grow to hundreds or thousands of pages. Naturally, you see how the workload starts to pile up. Every little change needs to be repeated over many pages, and subtle bugs will sneak in when you use a tool as unstable as LLM. I’ve seen LLMs remove blocks of code for no reason, or for reasons I don’t fully understand; Either way, my change is completely within my understanding. Will you verify every change? I assume you can’t write independent tests either, so are you going to test each file manually?

The SSGs

What works for one person works for all

Creating a simple website with a static site generator can take 20-30 minutes using Hugo. What you get is a dedicated tool that ensures the code is printed on all pages – what works for one works for all. When you make big changes, you update one template file and merge it, which only takes a second. You can use the LLM to make a transition, so the choice is not arbitrary, and the LLM can be a big part of your career.

SSG is a tool that solves a specific problem. The arrival of the LLM does not change the existence of that problem. However, an LLM is not the right tool for the job. Vibe coding a multi-page website without the right tools is a terrible waste of resources, and if you are serious about building a stable website, there is no better way than SSG.

SSGs and LLMs are tools at opposite ends of the spectrum. There’s no reason they can’t work together, but there’s a strong case against using LLM to create a sustainable website. If you do, and it’s more than a few pages, you should stop and reevaluate your approach. Some might say it’s subjective, but so is putting square wheels on a car. If someone wants to do that, who am I? Write that down; it’s stupid. As with square wheels, use the right tool for the job.
