Love this idea! Started building a version of it a while ago, but gave up because my resume time was too slow
My job has their own DCs, but inexplicably hosts devboxes in EC2 - an autosuspend feature for cost savings sounds awesome.
Feature request: let me give you a Dropbox folder to persist/load my suspended vms from/to, that way i dont get charged for storage when not using it, and i can walk away whenever i want
The Dropbox idea sounds super interesting
