Where IBM Cloud VPC (Virtual Servers) is strong

  • GPU and AI accelerator profiles, including NVIDIA H200 and AMD MI300X.
  • Spot instances at up to 75% lower cost, and reserved capacity options.
  • Multizone regions and confidential computing options.

Where Sandboxer differs

  • IBM VPC instances are generic VMs; Sandboxer ships an agent-ready Ubuntu VM with Docker, nested KVM and an API.
  • IBM bills hourly; Sandboxer bills per second and stopped sandboxes cost nothing.
  • Pause with memory, fork and per-port URLs are not described on the IBM pages reviewed.

Pick IBM Cloud VPC (Virtual Servers) if

  • You need GPU or AI-accelerator profiles or enterprise compliance on IBM Cloud.
  • You want multizone regions and reserved capacity discounts.
  • Your organization already standardises on IBM Cloud.

Pick Sandboxer if

  • You want a sandbox that stops with memory and disk saved and resumes with processes running, with stopped sandboxes costing nothing.
  • You want Docker, systemd, nested KVM, SSH and coding agents (Claude Code, Codex and others) already installed, with HTTPS URLs for any port, without assembling it yourself.
  • You want a per-second-billed Ubuntu 24.04 VM driven by a REST API, CLI, MCP server or TypeScript/Python SDK.
