+> The browser version doesn't support the `init`, `isServiceRunning`, and `startService` methods. You must ensure that the Foundry Local service is running before using the SDK in a browser environment. You can start the service using the Foundry Local CLI: `foundry service start`. You can glean the service URL from the CLI output.
