Estimated Cost

Median workload time x published rates at the 8 vCPU / 16 GiB sandbox spec. Excludes sandbox create/destroy time. This provider bills CPU on active usage, so the wall-clock figure shown is an upper bound.

Disk Usage

Total disk usage (du -sx) captured after each phase — a proxy for disk I/O and storage cost. Some providers report 0 here if their sandbox filesystem doesn't support usable disk-usage reporting.
