OpenShell
OpenShell is a managed sandbox backend for OpenClaw. Instead of running Docker
containers locally, OpenClaw delegates sandbox lifecycle to the openshell CLI,
which provisions remote environments with SSH-based command execution.
The OpenShell plugin reuses the same core SSH transport and remote filesystem
bridge as the generic SSH backend. It adds
OpenShell-specific lifecycle (sandbox create/get/delete, sandbox ssh-config)
and an optional mirror workspace mode.
Prerequisites
- The
openshellCLI installed and onPATH(or set a custom path viaplugins.entries.openshell.config.command) - An OpenShell account with sandbox access
- OpenClaw Gateway running on the host
Quick start
- Enable the plugin and set the sandbox backend:
{
agents: {
defaults: {
sandbox: {
mode: "all",
backend: "openshell",
scope: "session",
workspaceAccess: "rw",
},
},
},
plugins: {
entries: {
openshell: {
enabled: true,
config: {
from: "openclaw",
mode: "remote",
},
},
},
},
}
-
Restart the Gateway. On the next agent turn, OpenClaw creates an OpenShell sandbox and routes tool execution through it.

Workspace modes
This is the most important decision when using OpenShell.
mirror
Use plugins.entries.openshell.config.mode: "mirror" when you want the local
workspace to stay canonical.
Behavior:
- Before
exec, OpenClaw syncs the local workspace into the OpenShell sandbox. - After
exec, OpenClaw syncs the remote workspace back to the local workspace. - File tools still operate through the sandbox bridge, but the local workspace remains the source of truth between turns.
Best for:
- You edit files locally outside OpenClaw and want those changes visible in the sandbox automatically.
- You want the OpenShell sandbox to behave as much like the Docker backend as possible.
- You want the host workspace to reflect sandbox writes after each exec turn.
Tradeoff: extra sync cost before and after each exec.
remote
Use plugins.entries.openshell.config.mode: "remote" when you want the
OpenShell workspace to become canonical.
Behavior:
- When the sandbox is first created, OpenClaw seeds the remote workspace from the local workspace once.
- After that,
exec,read,write,edit, andapply_patchoperate directly against the remote OpenShell workspace. - OpenClaw does not sync remote changes back into the local workspace.
- Prompt-time media reads still work because file and media tools read through the sandbox bridge.
Best for:
- The sandbox should live primarily on the remote side.
- You want lower per-turn sync overhead.
- You do not want host-local edits to silently overwrite remote sandbox state.
Important: if you edit files on the host outside OpenClaw after the initial seed,
the remote sandbox does not see those changes. Use
openclaw sandbox recreate to re-seed.
Choosing a mode
mirror |
remote |
|
|---|---|---|
| Canonical workspace | Local host | Remote OpenShell |
| Sync direction | Bidirectional (each exec) | One-time seed |
| Per-turn overhead | Higher (upload + download) | Lower (direct remote ops) |
| Local edits visible? | Yes, on next exec | No, until recreate |
| Best for | Development workflows | Long-running agents, CI |

Examples
Minimal remote setup
{
agents: {
defaults: {
sandbox: {
mode: "all",
backend: "openshell",
},
},
},
plugins: {
entries: {
openshell: {
enabled: true,
config: {
from: "openclaw",
mode: "remote",
},
},
},
},
}
Mirror mode with GPU
{
agents: {
defaults: {
sandbox: {
mode: "all",
backend: "openshell",
scope: "agent",
workspaceAccess: "rw",
},
},
},
plugins: {
entries: {
openshell: {
enabled: true,
config: {
from: "openclaw",
mode: "mirror",
gpu: true,
providers: ["openai"],
timeoutSeconds: 180,
},
},
},
},
}
Per-agent OpenShell with custom gateway
{
agents: {
defaults: {
sandbox: { mode: "off" },
},
list: [
{
id: "researcher",
sandbox: {
mode: "all",
backend: "openshell",
scope: "agent",
workspaceAccess: "rw",
},
},
],
},
plugins: {
entries: {
openshell: {
enabled: true,
config: {
from: "openclaw",
mode: "remote",
gateway: "lab",
gatewayEndpoint: "https://lab.example",
policy: "strict",
},
},
},
},
}
Lifecycle management
OpenShell sandboxes are managed through the normal sandbox CLI:
# List all sandbox runtimes (Docker + OpenShell)
openclaw sandbox list
# Inspect effective policy
openclaw sandbox explain
# Recreate (deletes remote workspace, re-seeds on next use)
openclaw sandbox recreate --all
For remote mode, recreate is especially important: it deletes the canonical
remote workspace for that scope. The next use seeds a fresh remote workspace from
the local workspace.
For mirror mode, recreate mainly resets the remote execution environment because
the local workspace remains canonical.
When to recreate
Recreate after changing any of these:
agents.defaults.sandbox.backendplugins.entries.openshell.config.fromplugins.entries.openshell.config.modeplugins.entries.openshell.config.policy
openclaw sandbox recreate --all
Current limitations
- Sandbox browser is not supported on the OpenShell backend.
sandbox.docker.bindsdoes not apply to OpenShell.- Docker-specific runtime knobs under
sandbox.docker.*apply only to the Docker backend.
How it works
- OpenClaw calls
openshell sandbox create(with--from,--gateway,--policy,--providers,--gpuflags as configured). - OpenClaw calls
openshell sandbox ssh-config <name>to get SSH connection details for the sandbox. - Core writes the SSH config to a temp file and opens an SSH session using the same remote filesystem bridge as the generic SSH backend.
- In
mirrormode: sync local to remote before exec, run, sync back after exec. - In
remotemode: seed once on create, then operate directly on the remote workspace.
