CreateOS Sandbox vs Prized
Pick Prized if you want live forks of a running microVM and an all-day dev box that feels local. Pick CreateOS Sandbox if your sandboxes must run past 24 hours, live in the EU, accept an inbound URL or keep untrusted code inside an outbound allowlist.
Prized's per-second sandboxes are labelled beta by the vendor; its dev boxes are generally available.

Where CreateOS Sandbox Fits Better
What CreateOS Sandbox brings to this matchup, with a plain note on where Prized has the edge.
No session length cap; Prized sandboxes end 24 hours after create, paused time included.
An outbound allowlist by host, IP or CIDR, enforced on the host; Prized documents open outbound and no allowlist.
Two regions, eu and us; Prized sandboxes run in us-west-2 only.
CreateOS is SOC 2 Type II and ISO 27001 certified, with reports available under NDA. Prized states SOC 2 is in progress.
Where Prized is strong
Prized forks a running sandbox into live copies that keep the parent's memory, disk and processes, offers sandboxes up to 32 vCPU / 128 GB, and pairs them with dev boxes that sync two ways with your laptop and mirror ports to localhost. Its agent-facing docs are unusually complete.
Which to Pick
Pick CreateOS Sandbox if
- Agent sessions can run longer than 24 hours.
- You need an EU region or an inbound HTTPS URL into the sandbox.
- You must restrict outbound traffic and want an installable SDK.
Pick Prized if
- You need to fork a sandbox while it is still running.
- You need sandboxes larger than 8 vCPU / 16 GB.
- You want a remote dev box for Claude Code or Codex with two-way file sync on the same balance.
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 | Prized |
|---|---|---|
| Isolation | Firecracker micro-VM with its own guest kernel | Sandboxes (beta): Firecracker microVM with its own kernel, commands run as an unprivileged user without sudo; boxes: one VM per box |
| What persists | Disk stays until you destroy the sandbox; pause also saves memory and CPU state | Sandbox pause keeps memory and disk; live fork of a running VM into up to 31 copies; boxes keep an encrypted disk with snapshots |
| Create by API | Yes: REST API, six SDKs (TypeScript, Go, Python, Rust, C#, Java), CLI and MCP server | HTTP Sandbox API and prized CLI; Python and TypeScript snippets, no SDK package |
| 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 | Sandboxes: outbound internet allowed; no egress allowlist documented; no inbound from the internet |
| Largest size | 8 vCPU / 16 GB on Enterprise; 8 / 8 on Pro, 4 / 4 on Beginner, 1 / 1 on Free | Sandbox 32 vCPU / 128 GB RAM / 128 GB disk |
| Billing | Per second: $0.03616363 per vCPU-hour, $0.01159025 per GiB-hour, storage $0.0001584 per GB-hour | Sandboxes per second: $0.04 per vCPU-hour, $0.0125 per GB-hour memory; boxes hourly against a monthly credit plan |
| Self-host | Enterprise only, onboarded by our team | Not published (hosted only) |
| Built for | Sandboxes created by API for agent and untrusted code | Remote dev boxes for Claude Code and Codex, plus beta per-job sandboxes |
Common Questions
How long can a Prized sandbox run compared with CreateOS?
A Prized sandbox lives up to 24 hours from create, paused time included, or 60 minutes on the free tier. A CreateOS sandbox has no lifetime cap and runs until you destroy it, pause it or it auto-pauses after an idle window you set.
Is Prized fork different from CreateOS fork?
Yes. Prized forks a running sandbox into live copies with the parent's memory, disk and processes, up to 31 copies of a 1 vCPU sandbox. CreateOS forks only from a paused sandbox; each child gets its own id, IP and bandwidth ledger and the source stays paused.
Which regions do Prized sandboxes use?
Prized sandboxes run in us-west-2 only, while its dev boxes cover five AWS regions in the US and eu-central-1. CreateOS Sandbox offers eu and us, selected per sandbox at create time.
Can I block outbound traffic from a Prized sandbox?
Prized documents outbound internet as allowed and does not document an egress allowlist. On CreateOS, adding any host, IP, CIDR or wildcard rule switches the sandbox to deny-by-default, and the host enforces it outside the VM, so code inside cannot change it.
