The main idea is that Drupal 8 can use the same Drush tool, site_audit, to analyze how well your site is running. The module generates detailed reports that cover best practices, caching configuration, unused content types, and database statistics. It also provides insights into installed modules, security settings, user accounts, views, and Drupal Watchdog log entries.
The site_audit module is useful for developers and site administrators because it gives a clear overview of potential issues and performance bottlenecks. Many major Drupal hosting platforms offer similar reporting features, but having this tool available locally or on any server makes it easy to review your site’s status at any time.
For most Drupal sites, running site_audit is a smart step in profiling performance, identifying configuration problems, and ensuring the site follows recommended practices. It is one of those tools that quickly becomes an automatic part of any Drupal workflow.
