bcons - console.log for backend code is a useful Chrome extension developed by Karontek. It offers a convenient way to display debug information for server-side code within the DevTools panel. This tool enables you to send messages from your server code to the panel, providing essential data for debugging purposes in web development.

The extension not only showcases server-side data but also includes request data, session details, cookie information, and server errors or warnings. Additionally, you can access the messages via any web browser on the bcons.dev site under the 'Console' section, allowing for flexible usage even on older devices.
