Current Behavior

cmux browser uses WKWebView networking. Proxy behavior follows macOS/system networking and app process environment.

What Is Not Exposed via CLI

There is currently no first-class cmux browser proxy ... command for per-surface proxy routing.

Why: WKWebView does not provide CDP-style per-context proxy controls equivalent to Chrome automation stacks.

Workarounds

Configure system/network-level proxy for the environment where cmux runs.
Route traffic through an upstream gateway you control.
Validate behavior with explicit IP checks.

Verification

cmux browser open https://httpbin.org/ip --json
cmux browser surface:7 get text body

Compare returned IP against expected proxy egress.
