# Parallel agents / agent factory (Box) Use this when work should be **fanned out across many isolated environments**: N agents on N tasks, a config sweep, or sharding a workload — and each worker needs a *real* machine, not a coroutine. Box move: configure **one** box (clone, install, secrets), then **fork** it; each fork is an independent VM from that snapshot, so you skip re-provisioning every machine. ## Why Box - **Fork = a configured template** — one setup, N identical machines (disk-level, no re-clone per VM). - **True isolation per agent** — separate filesystem, dedicated IPv4, SSH; agents can even talk over the network. - **Fleet economics** — 50 VMs × 240 h/mo ≈ **$432 (Box)** vs ~$4,124 (E2B) / ~$7,160 (Modal). ## Honest scoping Box forks at the **disk** level, not memory — a fork does **not** keep the parent's running processes; re-run your start command after fork. For *running-process* fork or routinely **1000+ concurrent** VMs with <500 ms boot, E2B/Modal are built for that. Box's sweet spot: tens of persistent, cheap, fully-isolated machines. EU-only; 100 active VMs soft cap (raising). ## Prereqs `curl -fsSL https://box.ascii.dev/install | sh`, then `box login "$BOX_API_KEY" --json`. ## Recipe ```bash base="$(box new --json | jq -r 'select(.event == "ready") | .id')" box ssh "$base" -- bash -s < ./setup.sh # configure once for i in $(seq 1 10); do fork="$(box fork "$base" --json | jq -r 'select(.event == "ready") | .id')" box ssh "
