CreateOS Sandbox vs Zo Computer
Zo Computer suits a person who wants one always-on server with an assistant they can text. CreateOS Sandbox suits developers who need a fresh, isolated micro-VM for each task, created and destroyed from code and billed by the second.
Pricing at a Glance
CreateOS rates verified 17 October 2026. Zo Computer pricing as published on 17 October 2026. Rates billed per GB rather than per GiB, or as bundled sizes, are quoted as published rather than converted.

Zo Computer
Zo Computer Basic is $18 per month (4 cores, 32 GB RAM), Pro is $64 per month (16 cores, 128 GB RAM) and Ultra is $200 per month (64 cores, 512 GB RAM), each with AI credits, as of 17 October 2026.
Where CreateOS Sandbox Fits Better
What CreateOS Sandbox brings to this matchup, with a plain note on where Zo Computer has the edge.
Create, pause, fork and destroy isolated environments per job from an API; Zo's API sends requests to your Zo's agent instead.
A documented isolation boundary, a Firecracker micro-VM per sandbox; Zo does not publish its isolation technology.
Outbound rules per sandbox, enforced on the host, for code you do not trust.
Where Zo Computer is strong
Zo wires the agent, files, hosting, automations and messaging (SMS, email, Slack, Discord, Telegram) together on one always-on server, with large RAM allowances for a flat monthly price and nothing to configure in a terminal.
Which to Pick
Pick CreateOS Sandbox if
- Each agent run needs its own clean, isolated environment.
- You call sandboxes from your own code in TypeScript, Python, Go or another SDK language.
- You want to pay per second only while sandboxes run.
Pick Zo Computer if
- You want a personal AI assistant with its own server that you reach by text or chat.
- You want site hosting on a zo.space domain and automations without touching a terminal.
- You need lots of RAM on a single machine for a flat monthly fee.
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 | Zo Computer |
|---|---|---|
| Isolation | Firecracker micro-VM with its own guest kernel | Not published; docs describe a personal server per user |
| What persists | Disk stays until you destroy the sandbox; pause also saves memory and CPU state | Files persist with regular filesystem snapshots; paid plans always on, trial computers sleep when idle |
| Create by API | Yes: REST API, six SDKs (TypeScript, Go, Python, Rust, C#, Java), CLI and MCP server | REST API that talks to your Zo's agent, plus MCP server; no API to create isolated environments per job |
| 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; security doc says the AI can access the internet and download files |
| Largest size | 8 vCPU / 16 GB on Enterprise; 8 / 8 on Pro, 4 / 4 on Beginner, 1 / 1 on Free | Ultra plan: 64 cores, 512 GB RAM, 100 GB+ disk |
| Billing | Per second: $0.03616363 per vCPU-hour, $0.01159025 per GiB-hour, storage $0.0001584 per GB-hour | Monthly plans: $18, $64 or $200, including AI credits |
| Self-host | Enterprise only, onboarded by our team | Not self-hostable today |
| Built for | Sandboxes created by API for agent and untrusted code | A personal or small-business AI assistant on a dedicated cloud server |
Common Questions
Can Zo Computer spin up a separate sandbox for each job?
Zo does not offer an API to create, pause or fork isolated environments per job; its REST API sends requests to your Zo's built-in agent. CreateOS Sandbox creates a new micro-VM per call and lets you pause, fork or destroy it from REST or an SDK.
Is a Zo Computer plan cheaper than CreateOS for a big machine?
For a single always-on machine with a lot of RAM, Zo's flat plans are hard to beat: $64 per month buys 16 cores and 128 GB RAM. CreateOS bills per second per vCPU and GiB, which suits many short sandboxes rather than one large server kept on all month.
How does Zo Computer isolate my code?
Zo does not publish its isolation technology; its docs describe a personal server per user with the filesystem kept in an open-source container image format. Each CreateOS sandbox is a Firecracker micro-VM with its own guest kernel, root filesystem and network identity.
