Shout-out to Baty, who launched his gemlog successfully through this tutorial @ gemlog.baty.net.
FYI - There are similar API solutions available for GitLab and Sourcehut.
After more research, it seems that DigitalOcean and Vultr are priced similarly. However, Vultr has some lower-cost options for those who can't afford $5.00 per month.
