Mainuppermain is a term used in software design to describe a two-layer architectural pattern that separates the responsibilities of an application's entry point into an upper orchestration layer and a lower execution layer. It is not part of formal software engineering curricula, but has appeared in online discussions and informal writings as a descriptive label for modular design.
The exact origin of the term is unclear, and it is mainly found in community forums, tutorials,
In this pattern, the upper layer, or "main upper," handles bootstrap tasks such as configuration, wiring dependencies,
Projects adopting this approach generally place the upper layer at the project’s entry point, responsible for
Proponents argue that the pattern improves testability, readability, and portability by clarifying responsibilities and reducing tight
