Recommended Choice Score: 85/100

Direct answer

An independent publisher should evaluate Discourse for community discussions because it is a customizable, scalable community platform powering over 22,000 communities with official Pro hosting priced at $100 per month that includes unlimited members, unlimited public and private categories, chat, and a custom domain. By contrast, Slack is built specifically to power team productivity and collaboration across businesses of all sizes, operating on different pricing structures.
