Frequently asked questions

Do I need to open a port to use Cmdop?

No. The agent on each machine makes an outbound connection to its relay and keeps it open; nothing dials in. A joined machine works from behind NAT or a firewall with no port forwarding and no VPN. See How CMDOP works.

Is Cmdop just SSH with a chat window?

No. A Cmdop session belongs to the machine rather than to your connection, so it survives disconnect and you reattach to live state instead of a replay. The target needs a running Cmdop agent, not an SSH daemon, and no inbound port has to be open on it. See Where Cmdop fits for when SSH is still the better tool.

Can an AI agent use Cmdop to reach my machines?

Yes. A locally installed Claude Code or Codex session can use Cmdop’s fleet MCP server to list machines, ask a machine’s agent to do work, and run commands across the fleet. These tools reach other machines across the relay; they are not a local shell. See Give an assistant fleet access.

Which platforms does Cmdop support?

The cmdop CLI is distributed for macOS, Linux, and Windows. Start with Install Cmdop.

Are there official SDKs?

Yes. Cmdop publishes cmdop for Python (Python 3.10 or later) and @cmdop/sdk for Node. Both bundle the Cmdop core and drive it locally rather than being thin HTTP clients wrapped around a public web API. See the SDK overview.

What plans are available?

Free supports up to 3 machines, and Pro costs $5/month for up to 10 machines. Both include one relay address; Pro includes custom-domain eligibility. Team is planned and not currently offered. See Pricing.

How do I run my own relay?

Install the cmdop binary on the host that will run the relay, then use cmdop server create. The relay is embedded in the binary, so the supported deployment unit is that process rather than a separate Compose stack. See Deployment.

How do I report a security issue?

Email [email protected] with a description, reproduction steps, and potential impact.

Where can I get help?

Use the current CLI help (cmdop --help and cmdop <command> --help) for command-specific behavior. For a product or account question, contact Cmdop support.
