Agno
fast, full-stack, now framework-agnostic — after a churny v2
a high-performance, batteries-included library with a genuinely novel framework-agnostic runtime — but the breaking v2 rewrite and the phidata rename hurt its stability story.
agno (formerly phidata) is a fast, full-stack agent library plus agentos, a production api-server runtime for hosting agents. its standout move: as of v2.6 agentos became framework-agnostic, able to run agents from the claude agent sdk, langgraph and dspy behind a unified protocol — a real differentiator if you want one runtime over many frameworks. it's cross-provider with teams and workflows for multi-agent.
the caveat is churn: v2 was a breaking rewrite that made the core classes stateless and forced migrations, and coming on top of the phidata rename it dented the project's stability perception. the tech is strong; weigh the recent instability.
