Hey there I feel your pain, ironically this is what lead me to create a new tool for developers like yourself called VanityCert that takes away the headache.

My journey personally was with my previous company and we had the challenge of 1-n domains pointing at 1-n sub domains so a simple solution like certbot just didn’t work for us sadly. Not only that but my bosses were doing it manually and still paying for the certs which was consuming time and money. So over the course of a few months I wrote a solution to that problem to easily issue, manage, and renew 1-n certs for 1-n vanity domains. Was a good bit of work but for the last 2 years it’s been flawless and turned into a upsell and a money maker from a losing situation previously.

This is funny timing because we actually just put VanityCert on product hunt if you’re interested in checking out what I build. Would love your thoughts!
