Claude Managed Agents vs Dejima
Both run autonomous coding agents, but they split the work in opposite places. Claude Managed Agents keeps the agent's reasoning on Anthropic's infrastructure and runs Claude. Dejima runs the whole agent on hardware you own, with whatever vendor you like. The question is how much you want to hand off.

Short version: if you want a fully managed Claude agent and you're happy for Anthropic to run the orchestration while you configure it, Claude Managed Agents is built for that. If you want the entire agent running on a box you own, with any vendor, plus brokered host access and an audit trail, that's Dejima.
What Claude Managed Agents is
Claude Managed Agents, launched in 2026, splits an agent into a brain and a pair of hands. You define the agent (its model, prompt, tools, and skills) and Anthropic runs it. The clever part is decoupling the reasoning from the execution: the agent loop that handles orchestration, context, and the session lives on Anthropic's infrastructure, while the sandbox where code actually runs can live elsewhere.
That sandbox can be self-hosted in your own VPC, so the code an agent runs and the files it touches can stay in your environment. But the loop that drives it does not. The orchestration stays on Anthropic's servers, and it runs Claude. It's a managed service for teams that want Anthropic to operate the agent and are building on Claude. See Anthropic's writeup.
What Dejima is
Dejima doesn't split the agent. The whole thing runs on your hardware. See the overview.
Each project is an island, a container on your own box holding one or more agents. The agent process and its loop run inside the island; the only thing that leaves is the model API call to whatever provider you chose. You run Claude Code, Codex, OpenClaw, or others side by side, with your own keys. Host-file access is deny-all by default and granted folder by folder through a broker that writes every crossing to a tamper-evident log. Sessions are persistent and you attach to them from anywhere on your network.

When Claude Managed Agents is the better choice
Pick Claude Managed Agents if you want the orchestration handled for you. You're building on Claude, you'd rather configure an agent than operate one, and you want Anthropic to run the loop, manage context, and scale it. Self-hosting the execution sandbox gives you control over where code runs without running the rest. That's a real convenience, and Dejima asks you to run the whole thing yourself.
When Dejima is the better choice
Pick Dejima if you want the whole agent on hardware you own, reasoning included, with only the model call going out. You want to run more than one vendor's agent, not commit to a single brain. You want host access that's deny-all and brokered, and an audit ledger you can read and verify. And you'd rather own the box than hand the loop to a managed service.
Common questions
Does Claude Managed Agents run on my own infrastructure?
Partly. You can self-host the execution sandbox in your own VPC, but the agent loop that handles orchestration, context, and session stays on Anthropic's servers. With Dejima the whole agent runs on your own box, and only the model API call leaves.
Is Claude Managed Agents only for Claude?
Yes. Claude Managed Agents runs Claude. Dejima runs agents from multiple vendors, including Claude Code, Codex, and OpenClaw, on one dashboard, and you bring your own API keys and mix them freely across islands.
Should I use Claude Managed Agents or Dejima?
Use Claude Managed Agents if you want a fully managed, zero-ops Claude agent and you're fine with Anthropic running the orchestration. Use Dejima if you want to run the whole agent on hardware you own, mix vendors, and have brokered host access plus an audit trail.
