 ## Advanced Configuration
 
+### Fixed CDP Debugging Port
+
+Specify a fixed Chrome DevTools Protocol (CDP) debugging port instead of using a randomly assigned one.
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "LOCAL",
+  localBrowserLaunchOptions: {
+    port: 9222,
+  },
+});
+
+await stagehand.init();
+```
+
+<Tip>
+If no `port` is specified, a random port will be assigned.
+</Tip>
+
 ### DOM Settle Timeout
 
 Configure how long Stagehand waits for the DOM to stabilize before taking actions.
