Create a channel

Who can use this feature?
  • By default, all members except Guests can use this feature. Multi-Channel Guests may have limited access.
  • Available to teams on free and paid plans.

Slack channels are where the majority of your team’s conversations and daily work can take place. You can create as many channels as you need. There are two kinds of channels:

  • Public channels are for conversations open to your entire team. Anything posted to a public channel is browsable and searchable to all team members, except for Guests.
  • Private channels are for confidential discussions. A private channel is only visible to its members, and only members of a private channel can read or search its contents.
