As you may not know, all restdb.io databases can host a dynamic site on a custom domain (like this site).
We added a nice feature to enable secure (SSL/TSL) sites without any setup other than changing the IP your domain points to (technicality: change the "A" record).
We use Let's Encrypt to
provide the service and it's all automatic. The certificate is created on the first page access and is then updated every three months.
Read more about how to do it in the restdb.io documentation.
