The terminal is essentially a Linux instance. The following ports are available/accessible from outside.
For example, if you develop a web application, like Rails. By default, 3000 is for development. So you can do
rails server and you can connect to
<storage name>.wazaterm.com:3000. This is HTTP which is not secure. If you want a secure connection, then bring the server with 8443 port and access to it. You will see a lock icon on the address bar :)
Click the hamburger menu on the right top of the terminal. You would see the port numbers. If you click them, it opens as a new tab.
