Circle
Community software that looks like yours, not ours
Circle gives you spaces, events, courses and live streams under your own branding and domain. It is the more configurable answer to Skool, and the price reflects that. Worth it once a community is paying for itself.
Our note
The right answer when the community has to look like it belongs to you, and an expensive one before that is true. Against Skool it is more money and more control, which is the entire difference between them.

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.
