The NEXA SYSTEM.
Built for performance.
With the NEXA System, we develop custom websites on our own technology platform. Compare us using the AI you trust!
What sets us apart
Performance, security and control as the foundation
Active development since 2017
Continuously developed and expanded in-house since 2017. We build the core ourselves and keep it independent of third-party platforms and core dependencies.
The high-performance system
Optimized load times even for complex corporate websites with dynamic content, database connections and extensive media.
Reduced attack surface
A reduced attack surface through controlled architecture, no plugin dependencies and, optionally, no public login area for maximum security.
Custom development
No templates and no unnecessary restrictions imposed by off-the-shelf systems. Every website is tailored to the company's requirements.
Why the NEXA System?
A corporate website is now an important part of the digital infrastructure.
A modern website has to do more than display content. It must respond quickly, work reliably, be technically well structured and grow with the company. Many website systems rely on a combination of a platform, extensions and additional services.
The NEXA System as the perfect foundation:
Your project is developed individually and tailored precisely to your requirements without compromise. Nothing is impossible!

Which framework we use
Our framework speaks Google's language
The result
- low memory usage
- fast server response time
- short startup times
- stable operation
The Go-based web framework
The NEXA System is a web framework based on Go (Golang) that we have developed since 2017.
Go is a compiled programming language designed by Google for high performance, efficient memory management and parallel processing.
Ultra-fast in every area
The finished application, your website, is provided as a precompiled Linux binary.
This eliminates the need to interpret source code at runtime. Additional processing steps are reduced and the application can run efficiently.
A coordinated complete system
The server architecture and frontend are also specifically designed for performance, security and extensibility.
All components work together perfectly. Projects are programmed and supported personally by the creator of the system.
Performance that comes from the architecture
Speed is
a quality characteristic.
Performance is the one part of a website that cannot be made to sound better through marketing. Performance is measurable, reproducible and reveals how well the underlying software has actually been developed.
Every millisecond saved is the result of making the right architectural decisions.
- Real-world load times with an LCP under 0.6 seconds
- Static resources served directly from memory
- No runtime interpreter, resulting in faster processing per page view
- Proprietary caching system built directly into the architecture
- Short server startup times due to compact application size
- Fast deployments without lengthy interruptions
- Efficient database queries instead of generic standard queries
- Optimized compression for data transfer
- Fast load times even with dynamic content and high-resolution images
- High parallelization through the underlying architecture
- Low memory usage, providing more capacity for traffic spikes
- Optimized Core Web Vitals as a measurable result
What "high performance" means.
Real-world performance with an LCP under 0.6 seconds
For Largest Contentful Paint (LCP), the NEXA System achieves values of under 0.6 seconds at the 75th percentile. This means that at least 75% of all measured page views reach this value or better.
Even complex websites with database connections, embedded content and high-resolution images can be delivered with high performance.
| Metric | Google Target | Websites that achieve this | NEXA SYSTEM |
|---|---|---|---|
| TTFB — Time to First Byte how fast the server responds | < 800ms | 44% | ~250ms |
| FCP — First Contentful Paint how quickly the first content appears | < 1.8s | 55% | ~0.5s |
| LCP — Largest Contentful Paint when the main content becomes visible | < 2.5s | 62% | ~0.6s |
| INP — Interaction to next Paint how quickly the website responds to input | < 200ms | 77% | ~100ms |
| CLS — Cumulative Layout Shift how much the page shifts while loading | < 0.10 | 81% | 0.00 |

A frontend without unnecessary dependencies
Full control over every line of code
NEXA deliberately uses a lean vanilla tech stack. The frontend is based on hand-written HTML, hand-written CSS and hand-written JavaScript without additional framework layers such as React, Vue, Angular or jQuery.
Optimized for search engines and AI systems
NEXA uses semantic HTML, structured data (Structured Data) and a clear information architecture. This allows search engines, crawlers and modern AI-based systems to understand content more effectively.
Stable browser compatibility
NEXA follows stable web standards and deliberately supports robust baseline technologies. This keeps the website compatible with common browsers and devices over the long term.
No design limitations
NEXA does without prebuilt components and framework structures. This allows every design to be implemented exactly as planned, without technical compromises.
Fewer unnecessary components. More control
Security through controlled architecture
Fewer unnecessary components. More control.
NEXA deliberately reduces external dependencies and avoids unnecessary extension layers.
This creates a smaller and more controllable technical attack surface.
Optional zero-login architecture
For corporate websites or portfolios, an administration login can be omitted entirely.
This eliminates this classic attack point:
- no password attacks
- no brute-force attempts
- no publicly accessible login area
Integrated security mechanisms
NEXA includes, among other things:
- Prepared statements against SQL injection
- automatic Go context escaping against XSS
- SSL/TLS encryption
- Protection against classic local and remote file inclusion attacks
Controlled development
The core of the system is developed in-house. External dependencies are:
- reviewed
- versioned
- pinned

Built for long-term use
A website system that lasts
The NEXA System was deliberately designed to allow for long-term extensibility. New features can be integrated without rebuilding the technical foundation.
The architecture reduces dependencies on:
- external platform decisions
- changing framework ecosystems
- short-term technology trends
Why the architecture is worth it
What this means for your company.
The architecture of the NEXA System does more than ensure short load times. It creates a technical foundation that supports visitors, search engines and your company over the long term.
Better discoverability
Faster visibility
Search engines and AI systems understand well-structured websites more reliably. Semantic HTML, structured data and short load times provide a strong foundation for sustainable visibility.
Semantic HTML & Structured Data
High organic rankings
Short load times are among the confirmed ranking factors. At the same time, Google can crawl more content in the same amount of time and adopt changes more quickly.
Optimized crawl budget
Ready for AI search and agents
More and more users search through AI systems. The technical structure of the NEXA System makes it easier for modern language models to read and classify content correctly.
Optimized for modern AI systems
Stable operation
Less maintenance
The NEXA System includes performance optimizations at its foundation. Additional caching solutions or subsequent performance extensions are not required for page delivery.
Fewer components, fewer sources of errors
More security
A smaller attack surface reduces potential risks at the architectural level. Fewer external components mean fewer points that need to be maintained and secured.
Security starts with system design
Stable under high load
As visitor numbers increase, the system can be distributed across multiple servers without changes to the source code. This keeps the website reliably accessible even during traffic spikes.
Prepared for growth
Very flexible
Extensible
New features can be added at any time without having to redevelop the entire website. This allows the system to grow with your company.
Extend instead of rebuild
More control
The foundation is developed entirely in-house. This eliminates dependencies on third-party platforms, frameworks or changing roadmaps.
Proprietary technology platform
Future-proof
Technologies are constantly changing. The NEXA System relies on a stable architecture that can be operated long term and continuously developed further.
Developed for many years
