Pick Managed Agents when you want the hosted harness, event persistence, and cloud container to be part of the product foundation.
Comparison
Claude Managed Agents vs Agent SDK
Use this comparison when the real choice is between Anthropic-managed infrastructure and a programmable SDK stack you operate yourself.

At a Glance
The simplest difference is who owns the runtime.
Anthropic positions these as two different ways to build with Claude, not as synonyms.
| Dimension | Managed Agents | Agent SDK |
|---|---|---|
| Runtime ownership | Anthropic runs the harness, sessions, and cloud runtime for you. | You program against Claude Code capabilities and run the application in your own chosen environment. |
| Control versus convenience | Lower infrastructure burden, less direct control over the underlying runtime. | More deployment and orchestration control, more surface area to own. |
| Best fit | Best for long-running asynchronous work with managed infrastructure. | Best for custom agents, CI workflows, and apps that need Claude Code tools inside your own architecture. |
| Environment model | Environment objects define the hosted container, network rules, and mounted files. | Your app decides where it runs and how the environment is isolated or secured. |
Decision Guide
You are choosing a delivery model as much as an API.
The choice becomes easier once you stop treating “agent” as a single category.
Choose Agent SDK when
Pick Agent SDK when you want Claude Code’s tools and agent loop but need to program, deploy, and govern the runtime on your own terms.
Combine them carefully
Use both only after the first version is clear. Mixing them too early usually creates blurry ownership and confusing docs for your team.
Mental Model
The Agent SDK is programmable control. Managed Agents is hosted agent infrastructure.
This is the distinction that saves the most rework later.
The Agent SDK gives you the same tools, agent loop, and context management that power Claude Code, but it runs as a library in your own program. Managed Agents instead gives you Anthropic-managed sessions and environments. If your main reason for choosing one is “it sounds more powerful,” pause and ask who needs to own the runtime boundary.
FAQ
You do not need both products to prove the concept.
These answers usually settle the “hosted versus programmable” debate quickly.
Can Managed Agents be the faster first version even if we eventually want the SDK?+
Often yes. Teams that need fast validation with less infrastructure code can start with Managed Agents, then move to the Agent SDK if runtime control becomes the bottleneck.
Should I use both from day one?+
Not usually for the first version. Pick the path that matches the real runtime ownership you need today, then expand from there.
