About Atomic Agents
Atomic Agents builds agentic applications from single-purpose, reusable components, such as agents, tools and context providers, with typed input and output schemas, built on Instructor and Pydantic. The aim is predictable, maintainable pipelines that follow ordinary software engineering practice rather than opaque orchestration.
Atomic Agents is an open-source project written primarily in Python, with 6.3k stars on GitHub. It was last updated in August 2026.
