I just started using them and I like it. It’s a good balance of easy and secure for me. I just added the container to my stack and then use their UI to point a subdomain at the internal port. Security can go pretty extreme if you set up their whole zero trust thing.

An alternative similar option is Pangolin. I’ve seen a lot of people like it to avoid Cloudflare, but I haven’t used it myself. There still has to be an endpoint running it, so you’ll need an external VPS, which then adds a cost to the equation but at least you control it.
