is-a.engineer is a free service that provides subdomains to elligible users that request them. At the moment, we only support CNAME mappings and do not provide A record mapping. This is a hobby project by me, not created or funded by a company. It will stay up for as long as I feel I can support it. In the event I can no longer, I will hand the project off to anyone willing to keep it going. We use Cloudflare for our DNS provider, and interact with their API using Tenant (another project I made!).
