WordPress vs Custom Website: An Honest Comparison

WordPress is the better choice when the budget is small, when the site is mostly a blog with lots of articles, and when the owner wants to install plugins and change the design on their own. A custom website makes sense when speed, security and specific features matter more than the lowest starting price.

WordPress runs 39.6% of all websites and 58.3% of sites whose content management system is known, according to W3Techs data from October 2026. It is that widespread because it is free, has a huge choice of themes and plugins, and finding someone who knows it is easy.

We build custom websites with Nuxt and Laravel and we do not work with WordPress page builders. Read this knowing which side we are on. We have tried to say plainly when you do not need a custom site.

Below we compare speed, security and cost, follow what happens to plugins over three years, show our Lighthouse results and explain how content gets edited without a developer. At the end you will find our recommendations for a blog, a company website and an online store.

If you already know you need a custom site, see how our website development works, from the first call to launch.

Speed, security and cost: WordPress and custom sites

01WordPress speed

It can be fast, but that depends on the theme, the number of plugins, caching and hosting. A page builder theme with ten or so plugins loads a lot of scripts and styles the page never uses.

02WordPress security

The core is well maintained, the weak spot is plugins. Patchstack's report on 2025 found 91% of new vulnerabilities in the WordPress ecosystem in plugins, 9% in themes, and only 6 low priority ones in core.

03WordPress cost

Getting started is cheap, since the software and many themes are free. Later you pay yearly licences for premium plugins and themes, PHP and database hosting, and regular maintenance.

04Custom site speed

Each page loads only the code it needs. Our Nuxt sites score 90 to 98 for Lighthouse mobile performance, for example 98 for Vuk Studio and 95 for Medical Time.

05Custom site security

There are no popular plugins that bots scan en masse for known holes. Security still depends on code quality and on keeping the underlying libraries up to date.

06Custom site cost

The build costs more up front, because everything is made for your content. After that there are no plugin licences, and new features are planned with the team that built the site and knows its code.

Plugins and updates: a WordPress site three years in

Plugins and updates: a WordPress site three years in

After three years a WordPress site usually has more plugins than it started with, and some of them are no longer developed. Any update to core, the theme or the server's PHP version can break one of them, so updating turns into a task instead of a single click.

Year one is quiet. The site has a theme, a page builder, a contact form, an SEO plugin, caching and a cookie banner plugin. Updates mostly go through without trouble.

Year two brings new plugins: a gallery, multilingual support, a popup, a connection to some email tool. Each has its own author and its own update rhythm. Some move to a paid tier, and the licence becomes another yearly cost.

By year three the first real conflict tends to show up: one plugin update breaks the layout or the form, or the author stops maintaining a plugin. Patchstack reports that for 46% of vulnerabilities disclosed in 2025 the developer had no fix out by public disclosure, and the weighted median time to first exploit was 5 hours.

None of this is a reason to give up on WordPress. It is a reason to plan maintenance from day one: as few plugins as possible, a backup before every update, and someone who checks the site regularly. A custom site has fewer outside dependencies, but someone still has to update those.

Lighthouse: a typical WordPress theme and our Nuxt sites

Lighthouse: a typical WordPress theme and our Nuxt sites

A well built WordPress site can score very well in Lighthouse, but a typical site on a popular page builder theme usually falls behind on mobile, mostly in performance. For our side we have measured numbers. The WordPress side we describe in words, because the result depends heavily on theme, plugins and hosting.

What most often slows a WordPress site down: a page builder that adds a lot of HTML and CSS, a homepage slider, several web fonts, plugin scripts loaded on every page and images uploaded at full size. Lighthouse reports this as a slow largest contentful paint and long main thread blocking.

Our mobile results: Medical Time 95 performance and 100 SEO, Vuk Studio 98 performance, Mango pastry shop 90 performance and 100 for accessibility, best practices and SEO. NST Print and Mill Centar, built with Next.js, score 100 for accessibility and SEO.

The difference comes from building each page for its own content and preparing images for the web automatically. On the Mango site an 8 MB photo becomes 60 to 120 KB, so the site stays fast when the owner adds new pictures.

If you run a WordPress site, open Lighthouse in Chrome (DevTools, Lighthouse tab, Mobile mode) and compare. Lighthouse marks a performance score below 50 as poor, and that is a sign the site needs work whatever it runs on.

Editing content without a developer

Editing content without a developer

On both WordPress and a custom site you change texts, images, prices and news yourself, without a developer. The difference is how much freedom you get: WordPress lets you change layout and features too, while a custom site gives you fields for exactly the content that changes in your business.

On WordPress the owner can install a plugin, switch the theme or drag a new block into the page builder. That is a real advantage if you like to experiment, and a risk if nobody keeps track of what has been installed.

On a custom site the admin panel is built around your content: news, services, price list, gallery, translations. On the Mango site the owner just uploads the original photo and the site prepares it for the web. A new page type or a new feature is still a job for a developer.

There is a third route, a headless CMS: content is edited in a ready made content management system, and the site that displays it is custom built, for example with Nuxt. WordPress itself can serve as a headless CMS through its REST API. You get a familiar editor and a fast site, with a somewhat more involved setup.

Blog, company website or online store: what we recommend

01Content heavy blog

WordPress. If you publish articles regularly and the budget is limited, WordPress is a proven choice. With a lightweight theme and few plugins it will serve you well for years.

02Company website

It depends on the goal. If the site just needs to exist and money is tight, WordPress is a reasonable pick. If it has to bring in leads from search and ads, a custom site gives better speed and control over technical SEO, as with Vuk Studio, where each of six pages targets its own keyword group.

03Online store

For a small catalogue and standard checkout, WooCommerce can be enough. When you need special pricing rules, accounting integration or card payments through a local bank, a custom shop is simpler in the long run. We integrated Raiffeisen card payments with 3D Secure ourselves, for example.

04Campaign landing page

Custom. Speed affects landing page experience, which Google Ads takes into account in ad quality. One fast page with a clear message does not need a whole content management system.

05Multilingual site

Both approaches work, but on WordPress multiple languages usually means one more plugin to maintain. Medical Time runs on a Nuxt platform in 5 languages, with translations edited in the same admin panel.

06Portal or client area

Custom. NST Print and Mill Centar have a closed B2B portal with SEF e-invoices, something that would be hard to assemble from ready made plugins.

FAQ: WordPress or a custom website

Yes. You get an admin panel for the content that changes: texts, images, services, prices and news. A new page type or a new feature is a job for a developer, where on WordPress you would probably install a plugin.
First the content is exported along with a list of every existing page URL. The new site keeps those URLs wherever possible, and any that change get 301 redirects so you do not lose search rankings. After the switch, Google Search Console is monitored for errors.
Google does not rank a site by the system it runs on but by its content, speed and technical health. On a custom site we control those directly in the code, while on WordPress they depend on the theme and the SEO plugin. On Medical Time, technical SEO work raised Semrush Site Health from 90% to 98% in one week.
With us, the client owns both the code and the domain. That means you can change the company that maintains your site without rebuilding it.
A custom site costs more up front. WordPress is cheaper to start, but later brings yearly premium plugin licences and more maintenance. We give an exact price after talking through what the site needs to do, and our article on website costs explains what drives the price.
We do not build new sites with WordPress page builders. If WordPress suits you better, we will tell you so. We can review your existing site and tell you what state it is in and what it needs.
