There's good discussion on this here, and on Reddit.

In addition to all of that, the real moral of the story is to not use anything with dynamic billing for personal projects, even if there is a free tier. Always ensure that the free tier does not automatically turn into a paid tier.

That said, I've never used Netlify, so I don't know how they present this service at the time of signing up.

GitHub Pages is great for static sites, and included Jekyll build support is a bonus.
