This list of communities is dedicated to #buildinginpublic, full communities of indie hackers, creators, and solopreneurs who share transparently and confidently while growing an engaging audience. If you're a seasoned pro at building in public with an established audience, just starting out, or curious about building in public, you can surround yourself by likeminded builders.

Slack is a business communication platform which offers many realtime chat features, including persistent chat rooms (channels) organized by topic, private groups, and direct messaging. Slack is popular as a company communication tool, but offers realtime communication functionality to other types of communities as well.
