KolaOS detects development servers in your workstation and lists their ports under Previews. Start your repository’s development server, then choose Open preview for its port. The HTTPS preview supports hot reload, including servers that listen on the workstation’s localhost. You do not need to expose a public port on the node.

​
Share a port

1

Open sharing

As the workstation owner, choose Share on the port.
2

Choose readers

Select named people or enable Everyone. The workspace’s Who can open previews policy limits the audience. Everyone means everyone admitted by that policy.
3

Save and send the URL

Save the change and send the preview URL. Readers must sign in to KolaOS and belong to the permitted audience.
With Workspace members only, sharing is limited to people who can access the workspace. With Everyone in the organization, organization members can be admitted. The Anyone with a public link policy currently has the same signed-in organization boundary; anonymous public previews are not supported. Sharing applies to one port. It does not share your IDE, SSH access or other ports. A restarted server keeps that port’s sharing settings.

​
Make a preview private

Open Share, turn off Everyone, remove the selected people and save. Removed readers lose access, including open connections after the gateway’s next authorization check, normally within about 10 seconds. Only the owner manages a workstation’s previews. An admin can change the workspace’s preview policy but cannot open the owner’s IDE.

​
When a preview does not open

Check that the server is still running and that you opened its current port. A reader who is refused should check the signed-in account and ask the owner to review sharing. If the workspace policy excludes the reader, an admin must review the policy. See troubleshooting for startup and access failures.
