sessions
Durable managed agent sessions
Keep status, events, tool calls, runtime bindings, and trace views outside the sandbox so work remains inspectable and resumable.
Claude Managed Agents alternative
Managed Agents on Sandbox0 infrastructure
Sandbox0 Managed Agents gives teams a managed-agents backend with durable sessions, sandbox execution, persistent workspaces, vaults, and runtime policy. It is built for teams evaluating Claude Managed Agents semantics but needing more control over where agent work executes.
Comparison
Claude Managed Agents made the model visible. Sandbox0 focuses on runtime ownership.
This page compares product boundaries, not model quality. The useful question is which control plane should own session truth, and which infrastructure should execute files, shell commands, package installs, services, and tool traffic.
| Dimension | Claude Managed Agents | Sandbox0 Managed Agents |
|---|---|---|
| Control plane | Anthropic owns the managed agent session API and hosted control plane. | Sandbox0 owns the managed session API and routes sessions to selected agent harnesses. |
| Execution layer | Hosted execution by default, with self-hosted sandbox options for tool execution. | Sandbox0 sandboxes, volumes, network policy, vaults, and runtime observability are the execution substrate. |
| Session truth | Session and event truth live in Claude Managed Agents. | Session truth, event history, runtime bindings, and traces live in the Sandbox0 Managed Agents plane. |
| Harness choice | Claude Managed Agents follows the Claude managed agent runtime. | Sandbox0 can route sessions to Claude, Codex, and SandPi harness families behind one API surface. |
| Runtime ownership | Best when the hosted Claude Managed Agents control plane is the desired product boundary. | Best when teams want managed-agents semantics with deeper execution, persistence, policy, and deployment control. |
Sandbox0 backend
A managed-agents API backed by sandbox infrastructure.
Sandbox0 packages the repeated runtime work behind a managed session API: execution placement, workspace persistence, event history, traceability, vaults, and policy boundaries.
runtime
Sandbox-backed execution
Run files, commands, package installs, local services, and tool runtimes inside Sandbox0-controlled sandboxes.
workspace
Persistent workspaces
Use Sandbox0 volumes for repositories, artifacts, caches, harness state, and long-running agent workspace data.
vaults
Vaults and credential boundaries
Store model and service credentials outside agent source code, with egress-aware credential paths for tool traffic.
Pricing and API evaluation
Compare the operational boundary, not only the endpoint.
Teams searching for Claude Managed Agents pricing or API details are usually evaluating more than request syntax. They need to know where session state lives, how long-running runs are observed, which runtime executes tool work, and how credentials reach CLIs and services without leaking into agent-generated commands.
Sandbox0 keeps those runtime concerns explicit: the managed session API is the product surface, while sandboxes, volumes, vaults, and network policy remain inspectable infrastructure.
FAQ
Questions teams ask when comparing managed agents.
Is Sandbox0 a Claude Managed Agents drop-in replacement?
Sandbox0 Managed Agents follows a Claude Managed Agents-compatible API direction, but teams should verify the specific API surface they need before treating it as a complete drop-in replacement.
When should a team choose Sandbox0 Managed Agents?
Choose Sandbox0 Managed Agents when the managed session model is useful, but runtime ownership, sandbox execution, persistent workspaces, vaults, network policy, and observability need to be part of the platform boundary.
How is this different from Claude Managed Agents on Sandbox0?
Claude Managed Agents on Sandbox0 keeps Anthropic as the managed agent control plane and uses Sandbox0 as the self-hosted sandbox execution provider. Sandbox0 Managed Agents makes Sandbox0 the managed session API and control plane.
Use managed agent semantics on Sandbox0 infrastructure.
Start with Sandbox0 Managed Agents when you want a sessioned agent backend that keeps execution, workspace state, credentials, and observability under your infrastructure boundary.
