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).. Blaxel is Perpetual-sandbox agent runtime — spin up isolated sandboxes in milliseconds (resume ~25ms with memory intact), plus hosted agents, MCP servers, and batch jobs..
Fly.io Machines 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.
