WordPress vs Webflow vs custom code for Belgian SMEs (2026)

“Should I go with WordPress, Webflow, or something fully custom?”, easily the most-asked question in our intro calls. The short answer: it depends on what you actually want to do with your site after launch. An SME publishing three blog posts a month and adding products has fundamentally different needs than a software company with a static marketing site.

In this article we put the three most common stack choices for Belgian SMEs side by side. No jargon where we can avoid it, just the real trade-offs for your business.

The three options in a nutshell

WordPress is an open-source content management system that in 2026 still powers a significant majority of the web. It works with themes and plugins, you manage content via a dashboard, and you host it yourself or with a specialised provider.

Webflow is a commercial platform combining design, CMS and hosting. You build visually in the Webflow Designer, and your site runs on their infrastructure. You pay a monthly hosting fee directly to Webflow.

Custom code means a developer builds your site with a modern web framework like Astro, Next.js, SvelteKit or Nuxt, optionally paired with a headless CMS (Sanity, Contentful, Strapi). You end up with a statically generated or server-rendered site that’s fully yours.

Comparison table

Criterion	WordPress	Webflow	Custom (Astro/Next)
One-time build cost (SME site)	€1,500 – €8,000	€3,000 – €10,000	€5,000 – €25,000
Monthly cost (hosting + tools)	€15 – €80	€25 – €70	€5 – €30
Editing ease for non-technical users	Good	Excellent	Variable (depends on CMS)
Out-of-the-box speed	Mediocre (without optimisation)	Good	Excellent
SEO control	Full (via plugins)	Good, but bounded	Full
Plugin / extensibility	Massive (50,000+ plugins)	More limited	Unlimited, but DIY
GDPR & EU hosting	Yes, if you pick an EU host	US-hosted (needs extra DPA)	Yes, your choice
Vendor lock-in	Low	High	Low
Best for	SMEs with content, webshops	Design-driven brands, marketing sites	Apps, complex or high-performance sites

WordPress: the workhorse choice

WordPress is still the logical choice for most SMEs in 2026. You get a familiar dashboard, you can publish pages and posts yourself, and there is literally a plugin for everything (quote forms, booking systems, multilingual, customer portals).

Pick WordPress when:

• You publish content regularly (blog, news, case studies)
• You want a simple to mid-sized webshop (via WooCommerce)
• Non-technical staff need to add content without a developer’s help
• Your budget is limited but you want a professional result

Downsides:

• WordPress gets slow if you don’t maintain it. Plugins pile up, databases grow, and without caching and optimisation, load times creep towards 4 seconds, fatal for SEO and conversion.
• Security: WordPress is target number one for automated attacks. Weekly updates and a solid WAF (Wordfence, Sucuri) are not optional.
• The page-builder trap: tools like Elementor and WPBakery make building easy but produce bloated HTML that loads slowly and hurts SEO. A properly built WordPress theme (without a heavy page builder) is significantly faster.

At NIRO we build WordPress sites with custom themes, no page builders. That saves on average 60-70% in load time.

Webflow: design-first, for when marketing is the priority

Webflow has grown steadily in Flanders in recent years, especially with design studios, startups and marketing agencies. You build visually, but Webflow generates correct HTML, CSS and JavaScript behind the scenes, no Elementor mess.

Pick Webflow when:

• Design and visual quality are top priorities
• You want a marketing site you can quickly tweak yourself
• You don’t need complex integrations
• A second language is fine within Webflow Localization

Downsides:

• Hosting is tied to Webflow (US servers, EU CDN). For GDPR you need a Data Processing Agreement with Webflow, manageable, but it needs attention.
• High vendor lock-in. You can export your site as static HTML, but you lose the CMS functionality. Migrating to another stack is rarely simple.
• Limited extensibility. Webflow has fewer integrations than WordPress. Complex needs often require external services (Zapier, Make, Memberstack).
• E-commerce is limited. Webflow Ecommerce is significantly less capable than WooCommerce or Shopify.

Custom code (Astro, Next.js, SvelteKit): premium speed and control

A fully custom site built with a modern framework delivers performance and flexibility you can’t get from any platform. Our own site runs on Astro: sub-second loading, perfect Core Web Vitals, and we can adjust literally anything.

Pick custom code when:

• Performance is critical (e-commerce, lead-gen, SEO-competitive niches)
• Your site must integrate with existing systems (ERP, custom APIs)
• You’re building a web app or platform, not just a marketing site
• Your brand claims premium positioning, a slow WordPress site contradicts that

Downsides:

• Higher upfront cost. Budget €5,000-€25,000 for an SME site.
• Content management needs a decision. Either you wire up a headless CMS (Sanity, Contentful, Strapi), or you manage content via Markdown files in git (great for blogs, less so for non-technical users).
• You need someone who can maintain it. Not every web shop is fluent in modern JS frameworks.

Which fits your SME?

A rough rule of thumb:

• A bakery, restaurant, law firm or small local business mainly wanting a digital business card with occasional news → WordPress, built properly.
• A design studio, photographer or premium B2B brand wanting a visually strong marketing site they can fine-tune themselves → Webflow or a custom-built site on Astro.
• A SaaS company, e-commerce with serious ambitions, or an organisation needing deep integrations → Custom code with a headless CMS.

What about GDPR and Belgian hosting?

Often underestimated. The Belgian Data Protection Authority (GBA) has, since 2024-2026, become stricter on data transfers outside the EU. Concretely:

• WordPress on a Belgian or EU host (Combell, Hostnet, Hetzner, Scaleway): no issue.
• Webflow: servers are in the US. You need a DPA and must clearly disclose that data is processed outside the EU.
• Custom code: you pick the host. We host preferentially in Belgium or the Netherlands.

Our recommendation

For about 70% of our projects we land on WordPress with a custom theme, not because we love WordPress, but because it strikes the right balance of cost, flexibility and editing convenience for most SMEs.

For the other 30% we pick Astro or Next.js, for premium brands, e-commerce where every second of load time matters, and projects where the site is effectively an application.

We rarely use Webflow for clients, not because it’s bad, but because the combination of vendor lock-in and hosting cost over time usually works out more expensive than a well-built WordPress site.

Frequently asked questions

Is WordPress safe in 2026? Yes, if maintained correctly: monthly updates, a solid security plugin, regular backups, and as few plugins as possible. An abandoned WordPress site is a security risk, that’s what our hosting & support packages are designed to prevent.

Can I migrate from WordPress to custom code later? Yes, but it’s always a rebuild. Migrate your content (articles, pages) cleanly once and you’ll have a faster, more stable site afterwards.

Is Webflow cheaper because “you don’t need a developer”? At first glance, yes; over time, often not. Webflow hosting is more expensive than a Belgian WordPress host, and as soon as you need a Webflow specialist for changes, you pay specialist rates.

What about SEO? All three can rank well in Google if set up correctly. Custom code and well-built WordPress have a slight edge in load speed and technical SEO. Webflow does fine too, provided you take the SEO settings seriously.
