How To Make A Read-only Channel On Slack

Do you want a channel on your Slack workspace where only selected people can post? Do you want to stop other users from sending messages on the #general channel? Either way, we’re here to help you. Follow our guide below, and we’ll show you how to manage post permissions on your channels on Slack.


By default, all workspace members can post on the #general channel and other channels that they can access. In this way, they can send messages and communicate with other people within the workspace.

However, admins and workspace owners can restrict post permissions on a channel. They can create a read-only channel where regular members can’t send messages or share media.

If that’s what you want to do on your Slack workspace, our guide below can help you. Without further ado, let’s get started.

How to manage who can post on a channel on Slack

If you want to make a channel read-only for some or all members of your workspace, you can manage who can post within it. A channel is read-only for those who don’t have permission to post within it.

For all plans, you can manage who can post on the #general channel. As for those on a Business+ or Enterprise Grid plan, you can make any channel read-only.

You can only manage post permissions and make a channel read-only on the Slack desktop or web app. Follow our tutorial below, and we’ll show you how to do it on your #general channel.

  1. On your computer, open the Slack desktop or web browser app and sign in to your account.
  2. Go to the channel that you want to manage and click its name on the top left side of the conversation header. Alternatively, you can right-click on a channel’s name on the channels list and select “Open channel details” on the menu.

  3. Once the pop-up window appears on your screen, click the Settings tab.

  4. On the Posting permissions section, click Edit.

  5. Choose who can post on the channel and hit the Save Changes button to confirm your decision. You can also opt to disable threads to prevent people from replying to messages within the conversation.

Please note that only owners and admins can manage post permissions on a channel. If you can’t find the option to do so on your app, ask one of the owners or admins for help.

Like we mentioned earlier, only Business+ and Enterprise Grid users can manage channel permissions on all their channels. They can also do it with their channel management tools.

As for those on the Slack Free plan, admins and owners only manage post permissions on the #general channel.

To wrap things up

Now that you know how to manage post permissions on Slack, you can go ahead and create a read-only channel for regular members. Please note that you can choose exceptions to this rule and select people aside from admins who can send messages to the channel.
