Serveo is a ngrok like free alternative to expose your localhost

Serveo is an alternative to ngrok.

PRO: does not need to download a software or to register to a service

CONS: no fancy dashboard

usage

ssh -R 80:127.0.0.1:32775 serveo.net

it generates a subdomain like https://volens.serveo.net/  that redirect the traffic on your local machine on local port 32775: http://127.0.0.1:32775/

I'm using it on DDEV and works also with the XCode Simulator.
