What is the default port for OpenClaw's Canvas process?

Canvas, OpenClaw's agent-driven visual workspace, defaults to running on port 18793, separate from the Gateway's own port.

• Running as its own server process rather than sharing the Gateway's port reinforces the isolation between the two components
• Means a problem in Canvas doesn't necessarily expose or affect the Gateway's own network surface
• Should be considered alongside the Gateway's port when auditing which network ports an OpenClaw deployment actually exposes

Knowing both default ports matters for anyone auditing or hardening a self-hosted OpenClaw deployment, since an unaudited port left open is a common root cause behind real-world exposure incidents.
