Honban Alert is a free Chrome extension designed for web developers to enhance safety when working in production environments. It provides essential features like alert banners and request blocking to prevent unintended actions on specified domains. The alert banner is displayed on the designated website, serving as a visual reminder of the production environment while still allowing site interactions. However, it's recommended to disable the banner during design checks to avoid any layout issues.

In addition to alerting users, Honban Alert offers robust request blocking capabilities, preventing server requests to the specified domain. This includes blocking all types of requests, including asynchronous ones like Ajax. Users can easily toggle these features on and off via the extension's icon, and settings can be imported or exported for convenience. This tool aims to minimize accidental mishaps in production settings.
