Cloudflare Tunnel will spin up a free tunnel for you even without a Cloudflare account. If you run `brew install cloudflare/cloudflare/cloudflared` and then `cloudflared tunnel --url http://localhost:8080` you will get a URL you can use to reach that local port from the Internet.

I use it to share in-progress work with co-workers, test webhooks, etc.

Edit: fixed command thanks to comment below :)
