+### Browserless (hosted remote CDP)
+
+[Browserless](https://browserless.io) is a hosted Chromium service that exposes
+CDP endpoints over HTTPS. You can point a Clawdbot browser profile at a
+Browserless region endpoint and authenticate with your API key.
+
+Example:
+```json5
+{
+  browser: {
+    enabled: true,
+    defaultProfile: "browserless",
+    remoteCdpTimeoutMs: 2000,
+    remoteCdpHandshakeTimeoutMs: 4000,
+    profiles: {
+      browserless: {
+        cdpUrl: "https://production-sfo.browserless.io?token=<BROWSERLESS_API_KEY>",
+        color: "#00AA00"
+      }
+    }
+  }
+}
+```
+
+Notes:
+- Replace `<BROWSERLESS_API_KEY>` with your real Browserless token.
+- Choose the region endpoint that matches your Browserless account (see their docs).
