How it’s priced.Five rules, every row.
- 01The same work everywhereEach job is a number of runs, a length, a sandbox size and the CPU-seconds of work in each run (one vCPU busy for one second is one CPU-second). Every provider prices the same runs.
- 02Published list ratesEach provider is priced at the rates on its own pricing page, converted to dollars an hour, in the way it bills: for every allocated vCPU, for CPU used, or for a fixed size. The rates and the day each was read are below.
- 03Runtime's rates are the ones billing charges$0.025 per active vCPU-hour, above a floor of a twentieth of a vCPU, and $0.0075 per reserved GiB-hour of memory for the whole run.
- 04Compute onlyPlan fees, storage (except disk a provider bills while a sandbox runs), network, taxes, free credit and negotiated discounts are left out of every row. The dev box is priced as 730 hours of running time.
- 05Price, not speedRuntime's measured start and wake times, with samples and method, are on the speed page.
