Agno (formerly Phidata)

Agno (formerly known as Phidata) is an open-source Python framework designed to help developers build, monitor, and deploy intelligent AI agents. The framework provides clean abstractions to equip agents with memory, structured knowledge bases, and custom tools. By using a model-agnostic approach, it lets developers build agents that can reason, run code, and execute multi-turn tasks. The product is useful for Python developers, data scientists, and engineering teams building autonomous assistants, research bots, or customer support workflows. By using Agno, teams can coordinate teams of specialized agents, implement Agentic RAG, and query vector databases. It replaces the complex process of writing custom loop and memory tracking code. The main difference is Agno's focus on developer experience and visual testing. It includes a built-in agent UI called the Playground, which allows developers to test their agents and inspect tool executions in real-time. The core Python library is free and open-source under Apache-2.0, while paid tiers and corporate support agreements are available for enterprise deployments. For FutureStack, Agno belongs in AI Agents because its primary value is providing orchestration, tool-calling, and memory libraries for autonomous agent developers. It is best for Python engineers looking for a lightweight, modular framework to build agent teams. It is not for non-technical users seeking a plug-and-play chatbot builder.
