Common Questions
Is Coasty a sandbox or an agent?
Mainly an agent. Coasty is a computer-use agent platform with its own model and app integrations, and it also sells a Machines API for managed Linux or Windows VMs. CreateOS Sandbox provides only the machine, for running an agent you build or choose.
How much does a Coasty machine cost per hour?
Coasty lists running Linux machines at $0.05 per hour, Windows at $0.09 per hour, stopped machines at $0.01 per hour and snapshots at $0.01, billed per minute. It does not publish the vCPU or memory behind those prices, so a per-resource comparison with CreateOS is not possible.
Can Coasty run Windows desktops?
Yes. Coasty offers managed Windows VMs at $0.09 per hour, plus desktop apps for Mac and Windows. The CreateOS Sandbox desktop image, desktop:1, is a Linux XFCE desktop with Google Chrome and remote desktop and computer-use APIs.
