"quick" tunnels you can make by installing cloudflare software and running a command, without a cloudflare account, using a fixed "trycloudflare.com" domain and not your own domain.
existing (slow) tunnels you can create once you've set up your own domain for cloudflare to manage its DNS, installing cloudflare software, logging in to your account, and running a similar command.

edit: my bad, quick ones aren't new at all
