Apache Answer

Apache Answer is an open-source question and answer platform that gives a community or an internal team a place to post questions, tag topics, and collect answers and votes. Threads support accepted answers, follow lists, and moderation tooling for admins, and the layout takes cues from forum and stack overflow style sites.

Teams use it for technical support, onboarding, and knowledge sharing, while associations and open source projects run public communities with it.

Self-hosting keeps discussions and member records in your hands, avoids per-member pricing, and lets you manage database backups yourself.
