I built loves.rs, a free subdomain service for (mostly) Rust projects and developers (though it is open for everyone!) The idea is that if you have a project - for example, called harbor - you can claim a subdomain on loves.rs to showcase your project - like harbor.loves.rs. The subdomains are provisioned instantly so there's no waiting time between claiming the subdomain and being able to use it. Once you claim a subdomain you're given full DNS control over it, so you can add whatever DNS records you need yourself.
