When comparing Google Cloud Storage vs Bitbucket Pages, the Slant community recommends Bitbucket Pages for most people. In the question“What are the best website hosting providers?” Bitbucket Pages is ranked 9th while Google Cloud Storage is ranked 18th. The most important reason people chose Bitbucket Pages is:
BitBucket allows users to have free private repositories as long as it's a team smaller than 5 that is working on a project. In other words, BitBucket charges per team member and not per repository member. This feature may make BitBucket, even BitBucket pages better than for example GitHub for some, since the static page's source code won't be open source, but it can still be viewed on the browser, so for static page hosting per se it is not a big deal.
