A graphic showing a pie chart with three equally sized sections. The chart sections are labeled "No-Code", "Low-Code", and "Pro-Code".

The No-Code section has a speech from a power user  saying "I change screens, forms and simple processes myself.". The Low-Code section has a speech bubble from a business analyst saying "I change processes and simple business logic". The Pro-Code section has a speech-bubble from a developer saying "I change everything without any limitations".


Always remain updatable and agile. With Build.One there is no end of life.

A chart showing the effort of building and maintaining an application over time. There are two lines: One for development with classic code and one for the development with Build.One. The classic code line shows a very high effort during the application building phase. After that the effort decreases. After some time the effort goes up again, due to the first legacy Cycle. This pattern of high effort due to legacy cycles repeats again after some time.

The effort line for the development with Build.One is high in the beginning, but not nearly as high as the classic development line. After that the effort decreases and stays low, without any legacy cycles.
