Agno

Agno (formerly Phidata) is a performance-focused Python framework for multi-agent systems, bundled with AgentOS for running, tracing, and evaluating agents, with a free local runtime and flat-rate paid plans.

Agno is a Python-first framework for building agents and multi-agent teams, emphasizing performance and a batteries-included developer experience. It bundles model-agnostic agent construction with tools, knowledge (RAG), memory, and evaluation, and pairs the framework with AgentOS, a control plane where agents run and can be observed. Developers can run the entire local control plane, including chat, traces, sessions, knowledge, memory, and evals, for free on their own machine. Agno's commercial model is deliberately simple: the Pro plan starts at a flat monthly rate including several team seats and one live connection, with additional connections and seats priced per unit and no per-event, token, or egress fees. Enterprise adds self-hosting of the control plane, SAML SSO, an SLA, and a dedicated technical lead. This makes Agno attractive to teams that want predictable costs and a clear path from local development to production agent operations.
