Custom website performance is a direct revenue driver because Google uses Core Web Vitals as a ranking signal, and every 100ms of added load time reduces conversions by up to 7%. Sites built on Next.js 16 with server-side rendering and edge caching consistently achieve sub-second load times that template platforms cannot match.

We engineer performance at the infrastructure level. Static Site Generation (SSG) pre-renders pages at build time, while Incremental Static Regeneration (ISR) keeps content fresh without rebuilding the entire site. The result is a Largest Contentful Paint (LCP) under 1.2 seconds on mobile.

A B2B service provider saw a 38% reduction in bounce rate and a 2.1x increase in qualified leads within 90 days of migrating from WordPress to our Next.js architecture. The only change was the platform, same content, same ad spend.

Performance is not a feature we add after launch. It is an architectural decision made on day one that compounds over the lifetime of your site.

Decoupled architecture is a web development pattern that separates the frontend presentation layer from the backend data layer, eliminating the single-point-of-failure vulnerability that monolithic platforms like WordPress expose. This separation means your content management system is never publicly accessible, reducing the attack surface to near zero.

WordPress accounts for 43% of all websites and is the most-targeted CMS by attackers, over 90,000 attacks per minute according to Wordfence data. Our headless architecture using Next.js 16 and Sanity CMS has no public-facing admin panel, no plugin dependencies, and no database directly exposed to the internet.

Scalability follows the same principle. When traffic spikes, the static frontend scales through CDN distribution without touching your data layer. A site handling 1,000 visitors per day handles 100,000 the same way, no server upgrades, no performance degradation.

You get a website that grows with your business without accumulating the technical debt that forces a rebuild every two to three years.

Conversion-optimized web design applies behavioural psychology principles to interface structure, reducing friction between a visitor's intent and your desired action. Research from the Baymard Institute shows that 69.82% of online shopping carts are abandoned, with poor UX cited as the primary non-price factor.

We design every page around a single conversion goal. Visual hierarchy directs attention to your primary CTA. Form fields are reduced to the minimum required, each additional field decreases completion rates by approximately 11%. Mobile-first layouts ensure the 60%+ of visitors arriving on smartphones encounter zero horizontal scrolling or misaligned elements.

Our process includes heatmap analysis with PostHog, scroll-depth tracking, and A/B testing infrastructure built into the initial deployment. Design decisions are validated with data, not assumptions.

The difference between a beautiful website and a converting website is measurable. We build for the metric that matters to your business, whether that is demo requests, purchases, or qualified lead submissions.

Technical SEO is the practice of optimising a website's infrastructure so search engines can crawl, index, and rank its content efficiently. When SEO is treated as an afterthought, added via plugins or manual meta tags, critical elements like structured data, canonical URLs, and hreflang tags are often incomplete or inconsistent. Our approach embeds SEO into the build process itself.

Every page ships with JSON-LD structured data, automatically generated XML sitemaps, Open Graph and Twitter Card meta tags, and canonical URL management. For multilingual sites, hreflang annotations are generated programmatically across all locale variants. Croatian, English, German, and beyond.

Next.js 16 with React Server Components ensures Google receives fully rendered HTML on first request, eliminating the indexing delays common with client-side JavaScript frameworks. Combined with Core Web Vitals scores above 90, our sites consistently outperform template-based competitors in organic search within 60–90 days of launch.

SEO is not a service we sell separately. It is a standard engineering practice applied to every project.

Custom website development with Neviox gives you 100% ownership of your source code, intellectual property, and hosting infrastructure, unlike platform-dependent solutions where your business operates on rented technology. This ownership directly increases your company's valuation and eliminates vendor lock-in risk.

We operate as a long-term engineering partner, not a project vendor. After launch, our structured maintenance agreements cover security patching, dependency updates, performance monitoring, and feature roadmap planning. Most clients remain with us because an engineering team that already understands your codebase delivers changes 3–4x faster than onboarding a new team.

All code is documented with TypeScript 6 strict typing, tested, and stored in your own Git repository. If you choose to bring development in-house or switch providers, the handover is clean and complete.

The cost advantage of working with senior EU engineers in Croatia, rates 40–60% below Western Europe, means you invest the savings into features, marketing, or maintenance rather than absorbing inflated agency overhead.

Custom website development covers a range of architectures, each requiring different technology decisions based on the site's business objective. We deliver five primary project types, all built on Next.js 16 with TypeScript 6 and headless CMS integration as standard.

Corporate and Brand Websites: Multi-page sites that position your company, communicate services, and generate qualified leads. Built with Next.js 16 and Sanity CMS so your team manages content independently. JSON-LD structured data, ISR for always-fresh content, and Core Web Vitals optimization included. Typical timeline: 4–6 weeks.

SaaS Marketing Sites: High-conversion landing pages and product marketing websites for software companies. Performance-optimized for Core Web Vitals, instrumented with PostHog analytics, and built to support A/B testing from day one. Timeline: 3–5 weeks.

Multilingual B2B Portals: Full i18n support using next-intl. Croatian, English, German, and beyond, with proper hreflang implementation, locale-specific content, and SEO-optimized URL structures per language. Timeline: 5–8 weeks.

Industry-Specific Platforms: Tourism portals with booking integration, real estate sites connected to agency CRMs, healthcare clinic sites with appointment scheduling, and educational platforms, each built to the specific workflow of the industry it serves.

What Every Project Includes as Standard: JSON-LD structured data, XML sitemap generation, Open Graph tags, canonical URL management, WCAG 2.2 accessibility compliance, and Core Web Vitals optimization are included in every engagement, not sold as add-ons.

Choosing between custom development, WordPress, and Wix depends on your performance requirements, security posture, and long-term cost tolerance. Custom Next.js builds consistently outperform template platforms on Core Web Vitals, SEO control, and total cost of ownership over a 3-year period, while giving you full code ownership and zero platform fees.
