CreateOS Sandbox vs GitHub Codespaces
For people developing on a GitHub repository, Codespaces is the shortest path from a pull request to a ready editor. For agents that run code outside a repo context, for longer than 12 hours, or in many parallel forks, CreateOS Sandbox is the closer fit.
Pricing at a Glance
CreateOS rates verified 17 October 2026. GitHub Codespaces 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.

Where CreateOS Sandbox Fits Better
What CreateOS Sandbox brings to this matchup, with a plain note on where GitHub Codespaces has the edge.
No 12-hour running cap: a sandbox runs until you destroy or pause it.
Fork a paused sandbox, memory included, into parallel copies; Codespaces starts each codespace from the repo or a prebuild.
Not tied to a repository: create a sandbox from any image or template and exec into it.
Outbound allowlist enforced on the host; GitHub does not state an outbound policy for codespaces.
Where GitHub Codespaces is strong
Codespaces has the tightest GitHub integration available: one click from any repo or pull request into a dev-container-defined VM, with prebuilds, organisation policies and a free monthly allowance of 120 hours on GitHub Free and 180 on Pro.
Which to Pick
Pick CreateOS Sandbox if
- Agent runs last more than 12 hours or are not tied to a repository.
- You want to fork an environment into parallel attempts.
- You need outbound traffic restricted.
Pick GitHub Codespaces if
- Your code is on GitHub and people need a ready editor from a repo or pull request.
- You want dev container configs and prebuilds to standardise environments.
- You can live within the free monthly hours on a personal account.
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 | GitHub Codespaces |
|---|---|---|
| Isolation | Firecracker micro-VM with its own guest kernel | Dedicated VM per codespace with an isolated virtual network; dev environment is a Docker container inside it |
| What persists | Disk stays until you destroy the sandbox; pause also saves memory and CPU state | /workspaces persists; stopped codespaces auto-delete after up to 30 days |
| Create by API | Yes: REST API, six SDKs (TypeScript, Go, Python, Rust, C#, Java), CLI and MCP server | Yes: REST API and gh codespace CLI, tied to a repository |
| 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; firewalls block inbound internet and codespace-to-codespace traffic |
| Largest size | 8 vCPU / 16 GB on Enterprise; 8 / 8 on Pro, 4 / 4 on Beginner, 1 / 1 on Free | 32-core machine type (RAM not listed on the billing page) |
| Billing | Per second: $0.03616363 per vCPU-hour, $0.01159025 per GiB-hour, storage $0.0001584 per GB-hour | Hourly by core count, $0.18/hour for 2 cores to $2.88/hour for 32; storage $0.07 per GB-month |
| Self-host | Enterprise only, onboarded by our team | No (GitHub-hosted only); the dev container spec is open |
| Built for | Sandboxes created by API for agent and untrusted code | Ready-to-code environments for GitHub repositories |
Common Questions
How long can a GitHub codespace run?
A codespace has a maximum running lifetime of 12 hours and a default inactivity timeout of 30 minutes. A CreateOS sandbox has no lifetime cap, and idle auto-pause is something you opt into with a window from 60 seconds to 24 hours.
Do GitHub Codespaces offer GPU machines?
Not generally. GitHub ran a GPU machine type trial for selected customers, and it is not generally available. CreateOS Sandbox also has no GPU shapes, so neither fits GPU workloads.
Is CreateOS priced the same way as Codespaces?
No. Codespaces charges per core-hour with RAM bundled, $0.18 per hour for 2 cores, plus $0.07 per GB-month of storage. CreateOS prices vCPU and memory separately per second, at $0.03616363 per vCPU-hour and $0.01159025 per GiB-hour, so the cheaper option depends on your memory-to-CPU ratio.
