Discuz! is an open-source site-building system for forums, brand communities and enterprise internal culture communities. Its official site states: “over 3 million sites use it,” with “25 years of technical accumulation,” and describes Discuz! as comprehensive and powerful, user-aware, operation-aware, high-load and more secure.

Discuz! X5.0 is presented as a newly upgraded framework system with all-channel, multi-terminal coverage and support from 7000+ plugins and templates. It covers community portals, forums, circles/groups, article blogs, Q&A, points malls, rankings, video centers, exam centers, VOD/live streaming, document libraries, mall systems, multi-language and advertising systems.

The product line includes Discuz!ᵂ public SaaS, Discuz! X Enterprise editions, Discuz! X3.5 and Discuz! X5.0. The public SaaS platform is described as requiring no server and ready to use out of the box; self-hosted deployments should plan servers, databases, operations, backups, updates and patches. For higher traffic, the official site describes Web/database separation and RAID-5 scaling, and says Discuz! can support medium and large websites and portal-level applications.

For enterprise scenarios, Discuz! offers brand community, internal employee voice/community and international community solutions, with functions such as visual DIY pages, content and section management, user permissions and roles, content safety review and filtering, data backup and recovery, and integrations with OA/business systems, WeCom, DingTalk, Feishu and Douyin.
