Where Paperspace (DigitalOcean) is strong

  • CPU C-series sized exactly 4 vCPU / 8 GB at $0.08 per hour.
  • A range of NVIDIA GPUs (H100, A100, A6000, V100 and others), up to 8 per machine.
  • Notebooks and container deployments alongside machines.
  • Hourly machines that are powered off are billed only for storage.

Where Sandboxer differs

  • Paperspace has GPUs; Sandboxer has none.
  • Paperspace bills by the hour; Sandboxer bills per second.
  • Sandboxer saves memory so processes resume; Paperspace does not document that.
  • Paperspace also sells Gradient subscription plans for notebooks and projects alongside pay-as-you-go machines.

Pick Paperspace (DigitalOcean) if

  • You need GPUs for training, inference or notebooks; Sandboxer has none.
  • You want notebook-based ML development.
  • You want a flat monthly-rate machine (the C5 4 vCPU / 8 GB is listed at $48 per month).

Pick Sandboxer if

  • You need a CPU sandbox with Docker, nested KVM and systemd that stops and resumes with running processes intact, and you do not need GPUs.
  • You want coding agents (Claude Code, Codex and others) preinstalled and driven through a prompt API with streamed events.
  • You want per-second billing with stopped sandboxes costing nothing and a flat $20 to $2000 monthly plan whose dollars return as machine time.
