CreateOS Sandbox vs Cube Computer
Cube Computer is a good buy for a Mac developer who wants one always-on cloud box for Claude Code or Codex, set up in minutes. CreateOS Sandbox is the better fit when your software needs many isolated sandboxes on demand, controlled by API from any operating system.

Where CreateOS Sandbox Fits Better
What CreateOS Sandbox brings to this matchup, with a plain note on where Cube Computer has the edge.
An API, CLI and six SDKs to create sandboxes from code; Cube publishes no API.
Works from any OS: the createos CLI installs by script or Homebrew, while Cube's app is macOS-only.
Per-sandbox outbound rules and a choice of eu or us region; Cube publishes neither.
Where Cube Computer is strong
Cube is a low-cost, always-on agent machine with a polished Mac app that installs agents, gives each task its own Git worktree, and wires up SSH so any editor can connect. Paused machines pay for storage only.
Which to Pick
Pick CreateOS Sandbox if
- You need many separate sandboxes, created and destroyed by code.
- Your team works on Linux or Windows as well as macOS.
- You need outbound restrictions for code you do not trust.
Pick Cube Computer if
- You are one developer on a Mac who wants a personal cloud box for agents.
- You want agents installed and a worktree per task set up for you.
- You want one machine always on at a low monthly cost.
Head-to-Head Comparison
Every dimension side by side, checked on 17 October 2026 against each vendor's own docs and pricing pages. "Not published" means we could not find it on the vendor's pages, not that the feature is missing.
| Dimension | CreateOS Sandbox | Cube Computer |
|---|---|---|
| Isolation | Firecracker micro-VM with its own guest kernel | Not published; described as 'a full Linux computer in the cloud, like a VPS' |
| What persists | Disk stays until you destroy the sandbox; pause also saves memory and CPU state | Persistent SSD; paused machines keep files and pay for storage only |
| Create by API | Yes: REST API, six SDKs (TypeScript, Go, Python, Rust, C#, Java), CLI and MCP server | No API published; macOS app, SSH and phone access |
| Outbound network | Open with no rules; deny-by-default once any host, IP, CIDR or wildcard rule exists, enforced on the host outside the VM | Not published |
| Largest size | 8 vCPU / 16 GB on Enterprise; 8 / 8 on Pro, 4 / 4 on Beginner, 1 / 1 on Free | Spec sliders up to 16 processors, 128 GB memory, 500 GB disk |
| Billing | Per second: $0.03616363 per vCPU-hour, $0.01159025 per GiB-hour, storage $0.0001584 per GB-hour | Prepaid credit; 4 vCPU / 8 GB / 50 GB example $26.50/month; per-unit rates not published |
| Self-host | Enterprise only, onboarded by our team | Not published |
| Built for | Sandboxes created by API for agent and untrusted code | Keeping coding agents running 24/7 on one personal cloud machine |
Common Questions
Does Cube Computer have an API?
Cube does not publish an API; you manage the machine from its macOS app, over SSH or from a phone. CreateOS Sandbox is API-first, with a REST API, CLI, MCP server and SDKs in TypeScript, Go, Python, Rust, C# and Java.
What does a paused Cube machine cost compared with a paused CreateOS sandbox?
A paused Cube machine bills storage only. A paused CreateOS sandbox stops vCPU billing but still bills memory and storage, because it keeps the full memory image so processes resume intact, and it still counts toward your concurrency cap.
Can I use Cube Computer without a Mac?
Cube's app is macOS-only, though the machine itself is reachable over SSH once set up. CreateOS works from any system through its REST API, SDKs, or a CLI installed by script or Homebrew.
