# AI agent architecture examples

Interactive architecture diagrams of 244 open-source repositories with a GitDiagram architecture diagram where the diagram has an LLM or AI-model component and a component or group named as an agent, 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 AI agents here, the median diagram has 22 components. 77% draw a data store (most often a vector store, files on disk and SQLite), 48% have a command-line interface and 26% a web interface.

100% have an LLM or AI-model component, 39% speak MCP, 27% have a plugin or extension system and 30% are split into workspace packages (packages/, apps/, crates/ and similar).

The files their components link to most are index.ts (34), main.py (27), app.py (26), server.ts (22) and App.tsx (20).

Group names that recur: “agent runtime” (32), “user interfaces” (20), “agent execution” (12), “agent capabilities” (10) and “platform services” (8).

By language: Python 42%, TypeScript 33%, Rust 8%, Go 5% and Jupyter Notebook 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.
