I've been using S3 + Cloudfront + ACM for several years, and its fine but getting redirects from http is trickier than it should be. usually my https:// without a www. is unroutable, no matter whether I name the S3 bucket correctly, or if I set the cloudfront distribution to redirect requests, or if I use an ACM SSL certificate with a wildcard for the subdomain. Doesn't usually bother users but sometimes key people can get bounced.
I'm just curious if there was an equally cheap and but more autopilot modern static website solution. This solution costs like a few cents per month, whereas squarespace or any landing page site cost like $99/yr with a bunch of upsells.
If you want to play with a similar but different idea also check out Cloudflare workers.
