What is Atomic Agents?

Open-source Python framework for building AI agents with Pydantic schema validation and modular, composable components. Free, lightweight alternative to larger agent frameworks.

Atomic Agents is the anti-framework framework: it gives you typed I/O, composable agents, and nothing else you did not ask for.

Most Python agent frameworks (including [CrewAI](/tools/crewai) and [LangChain](/tools/langchain)) ship with layers of abstraction that promise flexibility but deliver debugging headaches. Atomic Agents takes the opposite approach. Every agent is a self-contained unit with Pydantic-validated inputs and outputs. You write normal Python. You debug with normal Python tools. There is no magic orchestration layer that swallows your stack traces.
