Cursor 3.7 adds `/in-cloud` for cloud subagents on dedicated VMs with reusable snapshots.

Cursor's June 17 release launches subagents on dedicated VMs, environment setup completing in under 10 minutes, with snapshots to speed future runs. Combined with the new Automations layer, it gives solo builders a way to offload long-running or parallel agent work off the laptop without hand-managing infrastructure. The snapshot reuse is the real win, since the first-run setup cost amortizes to near-zero on repeat tasks.
