Douban (豆瓣) is an interest-based content and community platform for Chinese users, often compared with film and book discovery and rating services such as IMDb and Goodreads. Its core capabilities include searching book, movie, and music entries, ratings and reviews, collection markers, and group discussions.

Douban is an online platform and does not provide official self-hosted software deployment; therefore, there are no conventional server, database, or container resource requirements. Users in China should pay attention to account, mobile app, and sharing workflows, while support for the WeChat ecosystem and domestic service providers depends on official capabilities.
