Rename DB Table Prefix is a utility plugin designed for WordPress users who need to change the default table prefix from 'wp_' to a custom prefix. This tool is particularly useful for enhancing security on sites that are already operational and are not using a multisite installation. The plugin leverages the power of the WP-CLI package, specifically the wp-cli-rename-db-prefix, which ensures a streamlined process for users familiar with command line operations.

While the plugin offers significant functionality, it is crucial to approach its use with caution. Users are strongly advised to create backups of their database and wp-config.php files before running the plugin, as there is a risk of causing site disruptions. This utility is free to use and falls under the category of utilities and tools, making it accessible for those seeking to improve their site's security and management.
