Could you build this?
No Building an isolated, secure, scalable infrastructure for executing untrusted autonomous AI agent code in real-time sandboxes requires deep cloud virtualization and security expertise.
What it would actually take: A platform like Castari requires architecting multi-tenant secure execution environments using technologies like Firecracker microVMs, gVisor, or hardened container runtimes, coupled with network isolation policies and eBPF observability. The primary technical hurdle is sub-second cold starts, persistent state snapshotting, and strict egress filtering to prevent sandboxed agents from abusing cloud resources or performing malicious network scans.
