There’re lots of free services that you can host your static website:

• GitHub Pages
• Netlify
• Gitlab

And many more. See Hugo Hosting & Deployment

I’ll show you how to deploy your website to Gitlab Pages. GitLab Pages is a feature that allows you to publish static websites directly from a repository in GitLab. It’s the easiest way to get your website up and running.

Hugo is one of the most popular open-source static site generators. I just heard that the new Bootstrap 5 will use Hugo to generate their document. With its amazing speed and flexibility, Hugo makes building websites fun again. You can build a beautiful website in less than an hour.
