Web and API Development with ASP.NET Core and .NET 10
The backbone of our corporate web, panel, portal and API projects. Microsoft's open-source, high-performance platform with long-term support.

What is ASP.NET Core / .NET 10 and why we use it
ASP.NET Core is Microsoft's open-source, cross-platform web framework; .NET 10 is its latest long-term-support release. It runs on Linux servers, ranks among the fastest web frameworks in the world and powers the most critical systems from banking to e-commerce. At Saybes we develop everything on the server side with this platform, from corporate websites to management panels, from customer portals to mobile app APIs.
Why .NET? Because performance, security and sustainability come together: built-in authentication and authorisation, data access with Entity Framework Core, a strong type system and test infrastructure, and Microsoft's regular annual release calendar. The code we write remains maintainable and extensible five years later; .NET developers are easy to find in Türkiye, so our clients never depend on us.
Saybes's own website, Mat Garaj's web + panel system, Aves Certification's certificate portal, İş Vinç's management panel, the Fonvio e-commerce platform and MatCRM all run on ASP.NET Core. We build SEO-friendly, server-rendered sites with Razor Pages / MVC and services that serve mobile and front-end apps with Minimal APIs and REST.
Six concrete reasons
Our technology choices are driven by performance, security and sustainability, not by fashion.
High performance
One of the fastest frameworks in TechEmpower benchmarks; it carries high traffic with little server capacity.
Security
Built-in authentication, authorisation, data protection and CSRF/XSS defences; regular security updates.
Long-term support (LTS)
Microsoft's three-year support policy; a predictable release calendar and a smooth upgrade path.
Entity Framework Core
Secure, versioned data access with SQL Server and other databases; schema management with migrations.
Linux and cloud ready
Runs in Docker and on Linux servers; deploys on Hetzner, Azure or AWS alike.
Broad ecosystem
Developers easy to find in Türkiye, mature libraries, thorough documentation; no lock-in risk.
ASP.NET Core / .NET 10 in our projects
How we position it in real projects and which work it carries.
Corporate websites
Server-side rendering with Razor, multilingual structure, SEO-friendly output, together with a management panel.
Management panels and portals
Role-based access, reporting, PDF generation (QuestPDF), file and document management.
Mobile app APIs
REST APIs serving Kotlin Multiplatform and Next.js apps, JWT authentication.
Integrations
WhatsApp Cloud API, payment systems, accounting (Luca), marketplaces and AI services.


OUR TECHNOLOGY APPROACH“Writing code that is still maintainable five years from now matters as much as delivering fast today. .NET makes that possible.”
The tools we use alongside it
An open, documented stack any team you choose can take over.
Services where we use this technology
Technology is a means, not an end; on the service pages we explain what we build and how.
Technical questions
Book a technical call →Does .NET only run on Windows?+
No. Since .NET Core it runs on Linux and macOS; we deploy our projects on Linux servers with Docker.
Why .NET instead of WordPress?+
For projects that need custom workflows, panels, integrations and performance, an off-the-shelf CMS becomes limiting. We do use WordPress for simple brochure sites; the decision depends on the need.
Can another team take over maintenance of the code?+
Yes. Standard architecture, documentation and the large .NET ecosystem in Türkiye make hand-over easy.
Can you extend our existing .NET project?+
Yes. We migrate legacy .NET Framework projects to .NET 10 and develop existing code bases further.
