Essentially the value is in not having to set up your own SSH server. Or for providing you with 'throwaway' domains for any developer who wants to temporarily expose some locally running service.

One use-case I had was connecting an Android app over 4g to a backend service running on my development machine, for some ad-hoc debugging. Using a tool like this was more straightforward than setting something more permanent up manually (spinning up a server, certificates, DNS, etc). Especially for someone not super familiar with how to configure the tools involved.
