By
Prateek YJ
More crust than filling. Mostly air.
Summary
Coasty is a cloud infrastructure platform designed specifically for AI agents, offering isolated virtual machines for each agent instead of shared environments. The platform provides true isolation with dedicated VMs that spin up sandboxed and tear down cleanly, eliminating risks from compromised agents affecting others. It claims to undercut major cloud providers like AWS and GCP and is built specifically for AI agent workloads including code execution, browser automation, and multi-agent pipelines.
