We use netlify for quite sometime with Hugo and we loved it.
Today, we use firebase hosting which is significantly cheaper and comes with its own CDN and free Google SSL. But I don't get CI from my git repo - I have to compile and push. Which I personally prefer.
But kudos to Netlify - I hope they realise that the value is not in CDN or CI or ssl certificates . But rather in building a CMS for static websites.
