Compute only: CPU plus memory, by the clock. Disk is left out because some providers include it and some meter it; ours is included. Cloudflare and Vercel bill CPU only while it is busy, so their meters run at full load. Modal prices a physical core as two vCPU. A RemoteHost sandbox that is asleep is billed nothing.
The same month, at your scale.
How many sandboxes run at once, and how many hours each runs in a month. It opens on fifty machines for 240 hours, the scenario Box's own calculator opens on.
Runtime only. Plan minimums sit outside it: ours starts at $20 a month on Starter, which covers the first hours at the same rate (pricing), and Box's is $20 too. Storage, egress and per-request fees, where a provider has them, are not included.
What each sandbox can do.
Read from each provider's own docs on 2026-09-11. Select any mark to read what it rests on: the note, the sentence it was read from, and where. Where the docs do not say, the mark says so rather than guessing either way.
