Creator here. While building my current startup, we had this requirement to offer custom domains to our users. We also wanted to serve those domains over HTTPS. After days of searching and brainstorming, I had no luck! I found a couple of potential solutions but they were either too expensive or too complicated.

So, I spent a few weeks building an in house solution that automates the whole process of provisioning and renewing SSL certs for our users. It involves Let's Encrypt and has been working great so far!

Last week I thought of offering this as a SaaS product. With the help of my friend, I coded an app where customers can add their domains in a few steps. It's live at https://autossl.co. Once a domain is added to our system, we generate a CNAME record for that domain. When the domain is accessed for the first time, we generate an SSL cert on demand through Let's Encrypt and renew it every 3 months. I also expose APIs to add domains to our system. So, if you are a SaaS company offering custom domains to your customers, you can completely automate SSL issuance in an easy and cost effective way.

I think it has got some potential. What do you think?
