# Python project architecture examples

Interactive architecture diagrams of the 1,000 most-starred open-source Python 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 200 most-starred Python projects here, the median diagram has 21 components. 58% draw a data store (most often a cache and a vector store), 37% have a command-line interface and 17% a web interface.

29% have an LLM or AI-model component, 25% speak MCP, 15% have a plugin or extension system and 12% draw a queue or event bus.

The files their components link to most are __init__.py (36), main.py (34), app.py (28), base.py (22) and pipeline.py (19).

Group names that recur: “user interfaces” (24), “agent runtime” (7), “platform services” (7) and “inference runtime” (6).

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.
