Sailboxes (Sail Research)
provider: "sail"
On what the box uses (CPU time, RAM it holds, disk $0.0007/GiB-h), sampled per second and not rounded up; RAM counts the VM's file cache, up to its memory limit (16 GiB at least), so file-heavy work can hold more than you asked for; paused/sleeping free; $0.01 per new Sailbox on the free plan, waived on Pro and Enterprise.
