OpenScale Sandboxes

provider: "openscale"

Per second on allocated size; no platform fee or minimum; paused = free; size comes from the template (E2B-compatible API); Singapore only; needs a pay-as-you-go key.

Always runs at 2 vCPU / 1 GB unless you pass your own image (image.openscale), so the router only sends it work that fits.
