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.
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.
Our note
Count the seats before comparing this to community software priced per workspace, because a hundred-member community is around $875 a month here and a flat fee elsewhere. Slack wins where the members are few, paying and already living in it, and loses badly where they are many and free.

Todoist
A task list that survives being ignored for a week
Todoist takes a typed sentence like "post the newsletter every Tuesday at 9" and turns it into a scheduled recurring task, which is the feature the whole product is built around. Five projects on the free account is enough for one person running one operation. Paying raises the limits, adds reminders and calendar layouts, and opens filters that make a large list usable. Teams get their own tier above that, and none of it tries to be a project management suite.
