Agno turns agent frameworks into an operating surface

Agent frameworks are starting to grow operating surfaces around the runtime itself. Agno's documentation describes an SDK and AgentOS runtime for building, running, and managing an agent platform where agents, multi-agent teams, and step-based workflows can run as services. The docs emphasize API-addressable agents, multi-user isolated sessions, tracing, scheduling, RBAC, audit logs, memory, knowledge, approvals, background hooks, remote execution, MCP, A2A, AG-UI, Slack, Telegram, and WhatsApp interfaces. For agent builders, the practical signal is to evaluate whether a framework stops at local orchestration or also provides the control-plane primitives needed to run agents as a product: authentication, per-user data isolation, observability, scheduled work, review gates, and data ownership in the builder's cloud.
