I know of the drawbacks of the approach and wouldn't chose it for a lot of my projects, but I would say it is very scalable in those cases where I would. Put the DB on GitHub Pages for free along with your HTML/JS code and you can scale to whatever GitHub is willing and capable of delivering. Yes, your users might transfer way more data than needed but you pay nothing for it and do not have to maintain servers.

In the standard scenario for personal projects (not enterprise) I would have a small VPS/Dedicated server with a REST service running - that would be hugged to death immediately if a link would make it to some site like HN. And also, I completely share the experience of the Author that after a couple of years you have moved on, the VPS is dead etc and you don't want to invest time.

Again, before considering using solution, be sure to understand how it works and the resulting limitations or you will likely chose wrong.
