Forum vs modern community platformKnowledge-base style threaded discussion (open source projects, B2B SaaS user forums): Discourse, Vanilla, Flarum. Engagement-first creator / membership communities: Circle, Mighty Networks (see community-platforms). Different mental models, different tools. 2. Audit moderation and spam protectionPublic forums attract spam and abuse. Tools with strong moderation (Discourse trust levels, Vanilla moderation queues) save admin time. Self-hosted forums without these features can swamp the moderator. 3. Plan for the community lifecycleForums need critical mass to feel alive. A quiet forum signals 'dead community.' Decide whether you have the audience and seeding capacity before launching; many forums die in their first 60 days from lack of activity. ## How we ranked these forum software We rank by real-world signal: G2/Capterra review volume and rating, and media mentions (volume and recency).
