Self-hosted Claude Managed Agents
Anthropic's 12 November notes let you run the whole Claude Managed Agents service on your own infrastructure.

The Claude Platform release notes for 12 November 2026 say Anthropic has launched self-hosted Claude Managed Agents. You run the whole Managed Agents service, not only self-hosted sandboxes, on your own infrastructure. You store agents, sessions, and session history there. The server sends model requests to the provider you choose. That provider is Anthropic by default. Access is by request through an Anthropic account team.
Self-hosted sandboxes, already on the platform, keep the agent loop on Anthropic's side and run tool calls on a worker you operate. This release moves the service itself.
Who it's for: a team that already wants Claude Managed Agents and needs the agent service, not just the sandbox, on infrastructure it controls.
Fits: Best Agent Builder stays n8n, for a workflow with triggers, branches, and a human approval step. A self-hosted Claude service is a different job. The agent builder guide and the n8n alternatives are unchanged. The verdict is unchanged.
