Yes, but I think lightsail egress is more expensive than s3 egress. On my phone, but isn’t lightsail 9 cents a GB to S3 being 8 cents? Think regular ec2 is 8 cents as well, or is that 12?

Lightsail includes a data transfer allowance, starting at 1TB, though importantly both data in and out is counted against the allowance. In the vast majority of cases, the allowance is enough. If you do use all the allowance, data transfer out charges are $.09/GB in most regions, the same as EC2 and S3, at least for the first 10TB.
