This question usually gets a biased answer, because whoever you ask sells only one of the two. I build on both. I build sites on clean code and I build WordPress plugins, so I have no reason to push you in either direction.
The question that settles it: who touches the site every week?
That is the main criterion, not the technology.
If you have someone in the company who changes text, adds pages, posts announcements and wants to do it on their own without ringing anybody, then WordPress. The dashboard is familiar, it is quick to learn, and you can find someone to help you in any town. That is its real advantage and it is a big one.
If the site changes a few times a year and you ring me anyway when something needs modifying, then an admin panel is a cost without a benefit. You pay for it in speed, in security and in monthly updates, for a convenience you never use.
What each one really costs you
WordPress is free right up to the moment you start using it. Then come the premium theme, the forms plugin, the SEO one, the cache one, the security one, the backup one. Each with its own annual subscription. And then comes maintenance, which is not optional: a WordPress left six months without updates is a security problem, not an aesthetic slip.
A site on clean code costs more to build and almost nothing per month. It has no plugins to update and no admin panel exposed to the internet.
Which one comes out cheaper depends on how long you keep it. At two years they usually even out. At five, they do not.
The speed difference, in numbers
I measured three real sites, on the same day:
| Next.js | Next.js | WordPress with Elementor | |
|---|---|---|---|
| Time to content | 286 ms | 472 ms | 1,007 ms |
| Requests to the server | 29 | 27 | 114 |
| Stylesheets | 1 | 3 | 59 |
The difference does not come from WordPress being badly written. It comes from the way it gets used: visual builders that load a separate stylesheet for every type of element, and plugins that put all their code on every page, including the pages where they do nothing at all.
A lot of that can be optimised, and I have written about speed separately, but you start behind and you stay behind.
Where security problems actually come from
This is where most of the nonsense gets said, in both directions.
WordPress itself is not insecure. The core is written by serious people, it is audited often and it updates itself for patch releases. From the annual reports of the firms that track vulnerabilities in the ecosystem, over 90% of them are in plugins, not in the core, and themes take up nearly all the rest.
So the risk is not “I have WordPress”. The risk is “I have twenty-two plugins, seven of which have not been updated in two years, and a login page the whole internet can see”.
Two practical conclusions come out of that. A WordPress with eight plugins chosen sensibly and updated monthly is a safe site. A WordPress left to its own devices is not a site, it is a problem waiting for a date. And a site on clean code has a structural advantage here, not because it is better written, but because it does not carry code from thirty strangers inside it and has no public front door.
The third option almost nobody mentions
The question usually gets asked as if there were two camps. There are not.
You can keep WordPress as the admin panel, where your person writes the way they always have, and put a separately built site in front of it, which takes the content through an interface and shows it fast. It is called the decoupled option, or headless.
When it makes sense: you already have a lot of content in WordPress, you have an editorial team that does not want to learn anything else, but speed and the technical side of SEO are hurting you.
When it does not: you have an eight-page brochure site. Then you are running two systems instead of one, paying for two lots of hosting and complicating a problem that does not exist. I have said this to people who came to me set on going headless.
When I choose WordPress without thinking twice
A blog with several authors, where people with no technical idea write and publish on their own. A site that changes often, with promotions, events, weekly announcements. A company that already has someone good at WordPress and is happy with them, because I do not fix what is not broken. And a tight budget now, with a need for something that works quickly.
When I choose clean code
A brochure site that has to be fast and has to be found, the most common case of all, where the content changes rarely and speed and technical SEO count for a lot. An online shop with many products, where every tenth of a second on the product page shows up in sales. Something that is not really a site at all, like web applications, client areas, calculators and configurators, where WordPress struggles and you can see it struggling. And the situations where security matters more than average, because without a public login page and without third-party code, the attack surface is simply a different one.
What is not a criterion
“WordPress is no good for SEO.” False. Google indexes HTML and does not care what generated it. A well-kept WordPress beats a badly written clean-code site any day of the week.
“Next.js is more modern.” That is not an argument. Modern does not pay bills. The question is what it costs you in time and what it brings you in clients.
“I want to be able to change things myself.” That looks like a criterion, but it is worth checking. Ask yourself honestly: in the last year, how many times did you actually go in and modify something? If the answer is “twice”, you are paying for an admin panel on every single visitor, for two edits.
The awkward question: who takes over if I disappear
This is the part where I damage my own argument, but it is a fair question and it deserves an answer.
Anyone can take over a WordPress. There are tens of thousands of people working on it, in any town, at any price. A Next.js site gets taken over by a programmer, not a webmaster, and on the Romanian market there are fewer of them and they cost more per hour.
What I do so this does not turn into a trap: the code is yours and it sits in your repository, not in an account of mine. I use no closed system that only I can touch. And I write in the code why I did each thing, not just what it does, precisely for the person who comes after me.
If that answer does not put your mind at rest, it is a legitimate reason to choose WordPress. I am telling you so myself, even though I lose by it.
How I decide, in two minutes
I ask you who touches the site and how often, how many pages you have and how fast they grow, whether you need features that fall outside the pattern of a brochure site, and how long you intend to keep this site.
Out of the answers, one reasonable option usually comes. And if two come out, I tell you both, with what you lose in each. I do not sell you the one that suits me.
See what I have built, with figures measured on the live sites. Or write to me with what you have in mind and I will tell you honestly what fits you, even if the answer is “stay with what you have”.
