WordPress or custom website: when each option makes sense for SMBs and freelancers in Spain

Most articles on this topic are written by a WordPress agency that naturally concludes WordPress is the best option. Or a custom development studio that concludes the opposite. This is not that article.

I build custom websites with Next.js, so I have a clear interest in you choosing that route. But I also know there are cases where WordPress is perfectly valid, and telling you otherwise would be dishonest and a waste of both our time.

Here is the real comparison.

What WordPress does well

WordPress has been around since 2003 and has not survived by accident. It has real advantages worth naming before getting into the limits.

The ecosystem is huge. There is a plugin for almost everything: forms, bookings, online stores with WooCommerce, memberships, invoicing. This means a developer can build a functional website in far less time than starting from scratch, which directly affects the initial budget.

Content management is intuitive. If you publish articles, update prices, change text, or add photos frequently, the WordPress dashboard is familiar and you can manage it yourself without depending on anyone. That is a real advantage.

The upfront cost is lower. A decent professional corporate site in WordPress built by a developer in Spain can cost between 700 and 2,500 euros, versus SolidaWeb's custom packages starting at 790 euros + VAT for service websites without ecommerce.

When WordPress is the right choice:

• If you publish content very frequently (blog, news) and want to manage it yourself without touching code.
• If your budget is tight and you need to be online now.
• If you already have a working WordPress site and there is no technical reason to migrate.
• If your website is a digital brochure without complex forms, integrations, or specific business logic.

The real limits of WordPress

These are not opinions. They are documented technical consequences.

Continuous, mandatory maintenance. WordPress.org itself recommends keeping the core, plugins, and theme updated for security reasons. This is not optional: an outdated WordPress site is a frequent target of automated attacks. That means your time, or a monthly maintenance fee to an agency. With a modern custom build, that technical maintenance practically does not exist because there are no plugins to update.

Speed and Core Web Vitals. Popular visual builders like Elementor add layers of code the browser has to process even when you are not using them. Google measures this through Core Web Vitals (performance metrics that affect search rankings). A website built in Next.js without the overhead of a generic CMS and its plugins typically scores significantly better in PageSpeed Insights than the average WordPress site. You can check your own URL at pagespeed.web.dev.

The code is not always fully yours. WordPress itself is open source and belongs to you. But the paid plugins that make your site work (visual builders, forms, payment gateways, SEO plugins) have annual licences. If you stop renewing them, parts of the functionality may break or stop receiving security updates.

When plugins are not enough. If your business needs the website to do something specific (an online quote tool, a client portal, a complex booking flow, integrations with your ERP or CRM), WordPress grows towards stacks of multiple plugins interacting with each other. The more specific the requirement, the more costly and fragile that stack becomes.

What changes with a custom build

A custom build is not justified because it "looks more professional". It is justified when it produces a result that WordPress cannot deliver efficiently or at a lower total cost over time.

The code is 100% yours. No annual licences to renew to keep the site running. The Git repository I deliver at the end of the project belongs to the client forever.

No plugin fees. The only recurring cost is hosting (at SolidaWeb we work on Vercel, with plans from $20/mo for professional use) and the domain (from 9 to 20 euros per year). No licence renewals, no builder subscriptions, no surprises.

Speed built in. Sites built with Next.js start from an architecture designed for performance from the beginning: static generation where it makes sense, optimised images, zero unnecessary client-side JavaScript. It is not an afterthought, it is the foundation of the project.

Custom integrations. If you need a quote tool, a client area, an integration with your management software, or an AI automation module, it can be built exactly as your business needs it, not as the nearest plugin allows.

When a custom build is the right choice:

• If the website is the main channel through which clients come in or operations are managed.
• If you need specific integrations that the plugin ecosystem does not cover well.
• If you have sensitive data requirements that cannot be hosted on a third-party SaaS.
• If the accumulated maintenance costs of a complex WordPress site exceed the difference in initial investment.

Summary table

The question that settles it

Is the website going to be a central business channel or a digital brochure?

If it is a brochure you update yourself frequently: WordPress is perfectly valid.

If it is a lead generation channel, a management system, or something that needs to work reliably with custom integrations: a custom build saves headaches and, over the medium term, also money.
