Worth noting WhatsApp also provides link previews now. Although it is supposedly e2e communication, the link previews are likely generated by reaching out to a similar facebook unfurl service.

They can then have a single map of phone num -> links rendered between fb and whatsapp.

Serveo is another good alternative to Inlets or ngrok that is completely free and pretty flexible: https://serveo.net/

In the list of eligible models:

"MacBook Pro (13-inch, 2019, Four Thunderbolt 3 Ports)"

I'm certain they previously would have specified that model with "Touchbar" rather than the number of thunderbolt ports...

RIP Touchbar!
