500+ AI Agent Projects & Use Cases is a curated repository of working AI-agent examples, tutorials, and reference implementations. It organizes hundreds of projects across popular frameworks such as LangGraph, CrewAI, AutoGen, Agno, and LlamaIndex, covering use cases in healthcare, finance, education, cybersecurity, research, automation, and other domains.

The collection is designed to be practical rather than purely conceptual. Many agents are self-contained with their own dependencies and environment templates, allowing developers to inspect or run individual examples without configuring a large monorepo. The repository also compares major agent frameworks and helps readers choose between lightweight agents, role-based multi-agent systems, stateful graphs, code-oriented workflows, and document-focused RAG pipelines.

It is useful for developers looking for implementation patterns, researchers surveying the agent ecosystem, teams evaluating frameworks, and students learning how agent architectures work in real projects. Instead of prescribing a single stack, the repository acts as a broad map of the agent landscape and a starting point for adapting existing examples to new applications.
