How to Enable the Built-in Web Server in RetroArch on Linux

RetroArch includes a native web server feature that allows users to access the interface and manage content remotely through a web browser. This article provides a concise walkthrough for Linux users to activate this network capability within the application settings. By following these instructions, you can configure the necessary ports and permissions to establish a successful connection between your host machine and client devices.

Launch RetroArch and Access Settings

Begin by opening the RetroArch application on your Linux desktop or handheld device. Once the main menu loads, navigate to the Settings option located in the vertical list on the left side of the screen. Scroll down until you find the Network section, which contains all options related to online functionality and remote connections.

Configure Network Settings

Inside the Network menu, locate the option labeled Web Server. Toggle this setting to the On position to activate the service. You may also need to specify the Web Server Port if the default value conflicts with other services on your system; the standard port is usually 8080. Ensure that your Linux firewall allows incoming connections on this specific port to prevent connection blocks.

Save Configuration and Connect

After enabling the server, return to the main menu and select Save Current Configuration to ensure the changes persist after closing the application. You may need to restart RetroArch for the network changes to take full effect. Once restarted, open a web browser on another device connected to the same network and enter the IP address of your Linux machine followed by the designated port number to access the interface.
