Keylinx Arrow


Keylinx is a full stack digital agency and a turnkey supplier of total solutions with offices in Gothenburg and Jönköping. Together we strengthen your innovation, specifically within the following three areas:

#undertaking - We see the big picture where we first identify the needs and opportunities before we build and deliver a ready-made product that fits your business perfectly. Together we ensure that the product lives with the business and develops in the same direction. Keylinx also delivers deep knowledge as resources in teams on-site.

#webb - We deliver added value in form of design, security, content and digital marketing. Keylinx offers continuous service, ranging from managing content updates to upgrading the platform and avoiding attacks. We build your concept and emphasize your brand on the web.

#mobil - We deliver modern mobile apps, from concepts to Google Play, Store, and AppStore. We build everything from basic information apps to advanced user-specific experiences.



Our services are often based on a publishing system (CMS). We are experts in Wordpress, Umbraco and DotNetNuke since we like open source options. However, we have years of experience with other proprietary products such as Lithium and EPiServer. We build and develop concepts and elevate your brand on the web.


We have many years of experience building custom apps ranging from games to standard information apps. The framework which we prefer and where we excel in competency is Xamarin. We also have many years of experience with native environments like Objective-C, Swift, Android Studio, Java and UWP with C #.


Undertakings where we do the whole deal are our signum, here we build your system from start to finish. We use primarily the Microsoft stack with Asp.Net Core, Entity Framework and SQL Server on the back. The front page often uses a modern javascript library like ReactJS or AngularJS. When we develop windows desktop application, we often build them using WPF framework, to exploit the possibilities of using a test-driven methodology (TDD).
