Slack communities
Slack communities tend to be the professional end of the spectrum, organised in channels by topic and often run by a company or an industry group. Many ask for a short sign-up or an application, and conversation is calmer and more work-focused than Discord.
Slack communities on this page are grouped by what they are about, so you can jump straight to the corner of Slack you care about.
