Shaded rows are where the two answers disagree and both listings have answered. A row where one side has not stated a fact is left plain, because silence is not a difference.
NodeBB
Forum software you can host yourself
NodeBB is forum software in the old sense, with categories and threads, built on Node.js and released under the GPL. You can run it on your own server for nothing, or pay NodeBB to host it and keep the plugins and backups somebody else's problem. Hosted plans are sized by pageviews rather than by seats, so a busy community with three moderators costs the same as a quiet one with thirty.
Our note
Take the self-hosted route only if somebody on your side is comfortable keeping a Node application patched. Otherwise the $20 plan is cheaper than the hours, and it is the same software either way.
Slack
Channels for a community that outgrew a group chat
Slack organises a community into channels, threads and searchable history, which is what a paid membership community usually needs once a Discord server stops being enough. The free plan keeps ninety days of messages and ten app connections, and that history limit is what pushes most groups onto a paid plan rather than any feature. Guests from outside the workspace can be given a single channel. Paying by seat means a large free community costs more here than on software priced per workspace.
