31## Choosing a build path
32
33The three paths for building with Claude differ in how much control you keep and how much of the implementation you offload to Anthropic. The [Messages API](https://platform.claude.com/docs/en/build-with-claude/working-with-messages) gives you the most control: you write the agent loop and run your own tools and infrastructure. The [Claude Agent SDK](https://code.claude.com/docs/en/agent-sdk/overview) sits in between, providing the agent loop and tool execution in a process you operate. With [Claude Managed Agents](https://platform.claude.com/docs/en/managed-agents/overview), you offload the most: Anthropic hosts the agent loop, tool execution, and runtime for you.
