# Kotlin project architecture examples

Interactive architecture diagrams of 185 open-source Kotlin repositories with a GitDiagram architecture diagram, most stars first. Each diagram shows the project's main components, how they connect, and links every part to its file on GitHub.

Across the 107 most-starred Kotlin projects here, the median diagram has 21 components. 70% draw a data store (most often a cache and files on disk), 10% have a command-line interface and 8% a web interface.

15% have a plugin or extension system.

The files their components link to most are MainActivity.kt (45), App.kt (9), Main.kt (8), MainViewModel.kt (8) and MusicService.kt (7).

Group names that recur: “android app” (12), “app shell” (9), “app experience” (8), “configuration” (5) and “playback” (5).

Counted over GitDiagram's stored diagrams of public repositories, from the names their components and groups carry and the files they link to; the rules are the ones in the [2026 open-source architecture report](https://gitdiagram.com/open-source-architecture-2026). Stars are GitHub's when the diagram was last made. Rebuilt daily: hubs grow as more repositories' languages are known.
