Agno
Agno (formerly Phidata) is an open-source Python framework for building multi-agent AI systems, paired with AgentOS - a self-hostable runtime that turns agents, teams, and workflows into a REST API server with 50+ endpoints for runs, sessions, memory, knowledge, and evals. The optional os.agno.com Control Plane connects a browser directly to a self-hosted AgentOS instance for chat, tracing, and monitoring; Agno does not operate a separate multi-tenant inference API of its own.
