Runloop is Enterprise-grade Devboxes for AI coding agents on a custom bare-metal hypervisor — ~100ms command exec, ~25ms resume-from-standby at zero idle cost.. Fly.io Machines is A REST API that boots ephemeral Firecracker microVMs from OCI containers in a few hundred ms — a low-level sandbox layer for agents (see also Fly Sprites)..
Runloop has more — ★ 0 vs ★ 0 (live counts).
Often yes — many teams combine sandboxes & runtimes (managed). Check each tool's docs for interop; they solve overlapping but not identical problems.
