Yes it's very similar to ngrok or to tailscale funnels or to cloudflare tunnels because it's a SaaS offering that someone (my employer in this case) hosts for free for the world to use... However zrok is also self-hostable and yes you can set it up in daemon mode. Right now setting it up for more than one thing in daemon mode (referred to as zrok front door https://docs.zrok.io/docs/guides/frontdoor/) isn't quite as ergonomic as we would like (doable, just takes a wee bit more effort right now, you can read a post about it on our forum where someone did just that https://openziti.discourse.group/t/zrok-how-do-i-run-multipl...)
It won't timeout if you run it as a service in this way.
