Freestyle
Full Linux VMs for AI agents that boot fast, clone live and hibernate.
Freestyle (YC S24) builds VMs for AI agents intended for tasks running hours to weeks. Its site lists fast VM startup, live cloning of running VMs including memory, pause and resume with state intact, default-deny networking with per-VM rules, live preview URLs with custom domains, WireGuard tunnels to private networks, nested virtualization for Docker, and a full kernel with FUSE and eBPF. YC describes VMs that can be snapshotted and hibernated. Founded in 2024 in San Francisco by Benjamin Swerdlow and Jacob Zwang.

Elastic sandboxes for running AI-generated code.
Daytona provides secure, OCI-compatible sandbox 'computers' that spin up in under 90ms — with snapshots for persistent agent state. In 2026 it moved core development to a private codebase while continuing to run as a commercial platform.
