box hits 40,000 created sandboxes

box’s rapid usage growth suggests agent infrastructure is becoming a real bottleneck—and a meaningful market.

• –Full Ubuntu VMs, Docker, SSH, snapshots, and desktop access give agents more freedom than narrow container runtimes.
• –Per-second billing and low prices make large-scale parallel agent workloads economically practical.
• –Doubling in two weeks is strong traction, but reliability and provisioning capacity will become critical as usage accelerates.
• –Developers can bring Claude Code, Codex, or other agents instead of adopting a locked-in runtime.
