The free version is unfortunately hobbled but slack is a lot better than discord at least at critical things like "getting caught up on messages that were sent since you last read." Some friends and I recently started a discord server for an async D&D game and it's a real pain to get caught up. They have the same red "you were here" line and the same "X new messages" banner as slack, but discord's default scrolling behavior works against you.
