Where IONOS Cloud Compute is strong

  • Low entry prices: a 4 vCPU / 8 GB Cube lists at $0.026 per hour with 240 GB NVMe storage included.
  • Data centres in the EU as well as the US.
  • Per-minute pay-as-you-go billing.

Where Sandboxer differs

  • IONOS Cubes are plain virtual servers; Sandboxer adds an agent API, coding agents, fork and per-port HTTPS URLs.
  • IONOS lists fixed Cube sizes (Basic and Memory families); Sandboxer has four sizes with per-second billing.
  • Sandboxer stopped sandboxes cost nothing and resume with processes running; no such pause is described on the IONOS Cubes page.

Pick IONOS Cloud Compute if

  • You need EU data centres and a cheap general VM.
  • You want a stable VM rather than a pause/resume sandbox.
  • You need Windows or RHEL images with licence add-ons.

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.
