Why choose custom WordPress instead of generic themes

Option 1: Pre-built WordPress themes
Built for everyone, not for your brand
Pre‑designed WordPress themes are designs (often from marketplaces such as ThemeForest or the WordPress repository) that you can install and partially customize. They include ready‑made layouts and functionality, so a website can be set up quickly and without coding.
Many small businesses are drawn to prebuilt themes because of the low upfront cost (most cost less than 100 EUR, some are even free) and fast implementation. Using a prebuilt theme, a website can be published within a few days or weeks. These themes often include demo content and visual editors, enabling a polished look immediately after installation.
Advantages
Fast setup and low upfront cost.
Many design options “out of the box”.
Disadvantages
A prebuilt theme is not made for your brand, which means your brand will need to adapt to the solution.
To appeal to as many different users as possible, the solutions are bloated with unnecessary features, which slows down page load times.
You are constrained by the theme’s built‑in layouts and options. If you want to add advanced functionality or significantly change the design, this often requires workarounds or even editing the theme’s code.
You depend on the developer for regular updates and security patches. If the author stops maintaining the theme or is slow to release fixes, your site becomes vulnerable. Moreover, popular themes attract hackers, as any vulnerability in a widely used theme can affect thousands of sites.
Generic sites never stand out; they blend into a sea of similar ones.
Best suited for
Smaller companies or sole proprietors with basic needs (e.g., a brochure website, a simple portfolio, a contact form).
Hobby projects and personal blogs.
Associations or events where the priority is to set up a site with basic information quickly and at low cost.
Option 2: Pre-built HTML templates combined with custom development
An intermediate solution with hidden complexity
Another option for building a website is to use a pre-built HTML template, which is essentially a static website without a CMS. The template consists of HTML, CSS, and JavaScript files that a developer can manually integrate with WordPress and, as needed, add dynamic functionality such as contact forms, galleries, a blog section, or custom Gutenberg blocks.
This approach represents an intermediate solution between a fully static website and a full WordPress theme. It provides greater control over structure and performance, but it also requires more technical expertise for both integration and maintenance.
Advantages
Very low initial costs – a more affordable solution compared to purchasing and customizing a WordPress theme.
Speed and a lightweight footprint – HTML pages do not include plugins and additional WordPress features that often slow down website performance.
Greater freedom in development – developers have full control over code structure, design, and custom functionality.
Lower dependency on plugin updates – since most functionality is hand-built, there is no need to continually update a large number of plugins.
An excellent foundation for a “headless” approach – the HTML template can be used as the frontend for a headless CMS or API, enabling a modern website architecture
Disadvantages
HTML templates are also generic and require additional customization to align visually and content-wise with the company’s identity.
Many HTML themes include unnecessary JS files (e.g., animations, galleries) that need to be removed manually for better performance.
An HTML template by itself does not enable easy content editing without technical knowledge; this capability must be added later through the development of WordPress functionality.
Linking the static template with the WordPress backend requires an experienced developer.
A hand-built structure means that upgrades, extensions, and fixes require ongoing developer involvement.
Best suited for
Such a combination of a pre-built HTML template and custom development makes the most sense for:
Smaller businesses or startups that want a fast and cost-effective website but need some dynamic functionality (e.g., a contact form, a gallery, a blog).
Promotional (“landing”) pages or microsites for campaigns, where load speed and visual appeal are critical, and a CMS is not strictly necessary for day-to-day management.
Portfolios and personal websites, where content changes infrequently but unique design is important.
Projects where WordPress is used only as the “backend,” while the frontend is hand-built and optimized for specific needs (headless approach).
Option 3: Fully tailored WordPress development
Built for your brand
Fully custom WordPress development means building a unique theme that fully meets your design and functionality requirements. Everything is tailored to your business needs and often includes custom Gutenberg blocks or plugins for specific features, with minimal use of external plugins. This option also includes performance, security, and maintenance optimization. For all these reasons, we recommend it to clients who want a stable and high-performing website for the long term.
Long-term flexibility
Custom development means your site grows with your business. Adding new features, integrations, or a redesign happens without the constraints of prebuilt themes.
Better security and stability
By using a minimal number of plugins, we avoid redundant code and unnecessary external libraries, such as Google fonts, and dependencies on them. This reduces security risks and enables safer, more reliable website updates.
Strong performance
Our sites are built on our own boilerplate, which means faster loading, a better user experience, and an SEO advantage.
Advantages
The design is fully tailored to your brand.
Custom Gutenberg blocks simplify content editing.
Minimal use of external plugins means faster, safer, and more stable operation.
The system makes it easy to implement upgrades and add functionality.
Ownership of the code.
Disadvantages
The initial investment is higher than with themes.
Requires the work of experienced developers.
Longer development time.
Best suited for
Companies that view the website as a key tool for marketing and sales, plan for growth, and need advanced functionality.
Your website as a strategic tool
Prebuilt themes offer a quick and cost-effective starting point, but are suitable only for basic needs. Static HTML templates are sufficient for the simplest sites, but they quickly show their limitations, as they require technical expertise from you and hinder easy growth.
Custom WordPress requires a higher upfront investment, but it pays off over time in greater performance, flexibility, and scalability. It is the right choice for companies that see their website as a key tool for marketing and sales, as it provides a fast, secure, and unique platform that grows with your business.

Proxmox VE is increasingly used in more demanding production environments, so the question of how to protect such environments effectively is becoming ever more important. Backing up virtual machines is only one element. In practice, reliable replication, fast recovery, the ability to migrate across platforms, and proper access and infrastructure management are equally important.

Before going on vacation, we check whether we have documents, access to the bank account, copies of reservations, and insurance. We less often check whether our company also has a "backup plan" for its digital life. Where is its data stored? Who has access to it? Can we move it elsewhere? And would we be able to operate if a key provider suddenly became unavailable?

Imagine a completely ordinary situation. You step into an elevator; in front of you is a panel with floor numbers. Do you know how to use it? Of course you do. And that is exactly why today I am writing an ode to the elevator—the simplest user interface. The elevator’s user interface, if those few numbers can even be called that, exhibits the highest possible degree of intuitiveness—a quality for which almost no prior learning is required.

A multilingual website had been on our task list for a year and a half, but we never found the right time for it. Client projects, infrastructure, development, and other day-to-day commitments always took precedence, so implementation of the English version of the website kept getting pushed back. The issue was not a lack of content or expertise, but the process, which required too much time and coordination. We only found a solution once we integrated translation into our existing publishing process.
