Where Alibaba Cloud ECS is strong

  • Large global footprint: 31 regions and 107 zones.
  • Many billing models: pay-as-you-go, subscription, spot, reserved instances and savings plans.
  • GPU, bare metal and supercomputing cluster instance types.

Where Sandboxer differs

  • ECS is a general VM service; Sandboxer is a preconfigured agent sandbox with coding agents and an API.
  • ECS applies a 2-minute minimum to instances with 4 or more vCPUs; Sandboxer bills per second.
  • Memory-preserving pause, fork and per-port HTTPS URLs are not described on the ECS pages reviewed.

Pick Alibaba Cloud ECS if

  • You need regions in mainland China or Asia-Pacific.
  • You need GPU, bare metal or very large instances.
  • You want savings plans and reserved capacity for steady workloads.

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.
