If you don’t feel like Wix or Weebly is fit for the job, here’s a list of alternatives. Their site builder is top notch really. Nothing competes with them. But if you’re trying to diversify your subdomain portfolio, there are plenty of options.
Just need to be careful with free web host. Static site might cause less of a limit block, but it will happen. And some also require you to login to the panel once a month.
Hence why i have not suggested any free host such as those.
