Awesome AI Agents

A curated list of awesome AI agents, LLM frameworks, autonomous agent systems, and multi-agent orchestration tools for building intelligent applications.

AI agents are autonomous systems powered by large language models (LLMs) that can perceive, reason, plan, and act to achieve goals. This list covers frameworks, tools, and resources for building production-ready AI agent systems.
