Claude Managed Agents is Anthropic moving up the stack — from selling a model to running the agent runtime for you. Announced as a public beta in April 2026 (platform.claude.com/docs/en/managed-agents/overview), it is hosted agent infrastructure: Anthropic operates the loop, the scaling, and the plumbing, and you consume it as a service. Notion, Rakuten, and Asana were named among the first customers.
The mental model is build-versus-buy for the agent layer. Self-hosting — OpenClaw, Hermes-Agent, Paperclip — gives you control and portability but hands you the operational burden: updates, isolation, secrets, scaling, monitoring. "Managed" inverts that: Anthropic carries the ops, and you trade some control and portability for not having to run any of it. For many teams that is the right trade; for some it is not.
The questions that decide it are data and dependence. Where does your data live and who can see it? How hard is it to leave? What happens to your agents if pricing or terms change? "Managed" is genuinely less work — the careful reader’s job is to price in the dependence, not just the convenience.
