Agno

fast, full-stack, now framework-agnostic — after a churny v2

free — Apache-2.0 (open source)#teams-wanting-a-fast#batteries-included-runti

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.

the description above is ours, condensed from the ranking. pricing moves — check it on the vendor's own page before you rely on it.

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.

we researched this category against vendors' own pricing pages and licence files. that is where this line comes from — not from the vendor, and not from anything they paid for.
