Cons
Con No inline editing
Unlike some other popular repositories, there is no way to edit inline directly from the source browser. Although, you can easily open up a Theia-based IDE in the browser to edit and run your code by clicking the "Open in Cloud Shell" button. You will still have to commit your changes from the Cloud Shell command line, though.
Con Markdown styling is not as good as GitHub or GitLab
Your README files will not render as nicely as GitHub and GitLab, which may irritate you if you're migrating your repos with nicely-formatted docs.
Con Must set-up billing account
For all Google Cloud Platform projects you must enable Billing. This isn't uncommon for cloud hosting providers but it still could be considered a CON.
