>Render is a unified platform to build and run all your apps and websites with free SSL, a global CDN, private networks and auto deploys from Git.
Apart from the CDN, that's all available for e.g. Digital Ocean Droplets. But why would a CDN be needed for static websites?
It makes sense to use those services for all the additional stuff, like Netlify's offers:
>User identity, Serverless functions, Instant forms, Split testing & rollouts, Analytics, Large media
But for a basic web-app, where's the benefit?
And downloads shouldn't take too long. Basic 1Gbit connections give you 100Mbyte per second, 10M per 100mils. A landing page should be doable in 10M, and then there is at least one second left to load the rest of the page before the user can react and make a choice.
Cache only works the second time the user comes to your page. By definition, every user will experience slow loading the first time.
That said, it probably depends on your use case if it is worth bothering with a CDN or not.
