Gitalk is a comment system that uses GitHub Issues as a backend to store and manage discussions for websites. It provides a comment component built with Preact for embedding interactive discussion areas into web pages.
The system utilizes GitHub OAuth for identity verification, allowing users to authenticate through their GitHub accounts to manage comment permissions. It also includes a multi-language widget that supports interface translation based on browser settings or manual configuration.
The project covers broader capabilities for comment section management, including the ability to restrict administrative access for creating threads and controlling the visibility and sorting of comments.
