My team at work has been using Netlify to host static html generated by R Markdown. Primarily we use these HTML documents to share in progress analysis internally. It has been great to have our GitHub repos linked to Netlify so that when a new commit is pushed, the site automatically redeploys on Netlify. We also have a requirement that our HTML documents be password protected, so we've been using that feature from Netlify.
But, with the change to Netlify's pricing structure such that every git committer needs their own Netlify account, I'm not sure our non-profit org will be able to cover the cost. GitHub Pages is an alternative, but I don't think that will work with our private repositories and the requirements that the sites have password protection.
Any alternatives that others have used for hosting HTML output?
