Omnara with CreateOS Sandbox
Use Omnara with CreateOS Sandbox when you want Omnara to run the agent loop, approvals and audit history while CreateOS Sandbox provides the isolated machine. Omnara lists CreateOS among its pool machine providers, so the two sit at different layers. Use Omnara on its own with your laptop or VM if you do not need a hosted sandbox.

Omnara
Omnara states the platform itself is free; with Omnara credits, models bill at provider token rates and machines by active time, with machine rates not published, as of 17 October 2026.
What CreateOS Sandbox Adds
What CreateOS Sandbox brings to this matchup, with a plain note on where Omnara has the edge.
Each Omnara tool call can land in a Firecracker micro-VM with its own guest kernel.
Outbound rules are enforced on the host outside the VM, so an agent cannot rewrite its own allowlist.
Published per-second rates for the machine layer: $0.03616363 per vCPU-hour and $0.01159025 per GiB-hour.
Pause keeps memory and processes, and fork copies a paused machine for parallel attempts.
Where Omnara is strong
Omnara is an agent control plane rather than a sandbox, so one API covers the agent loop, approvals and audit history while you swap the machine provider underneath.
Which to Pick
Pick CreateOS Sandbox if
- You need the isolated machine underneath Omnara or another harness.
- You want direct SDK or REST control over sandboxes with no orchestration layer.
- You need egress allowlists and pause with memory for the machines your agents use.
Pick Omnara if
- You need an agent control plane with approvals, RBAC and audit history.
- You want to self-host the orchestration layer in your own VPC under Apache-2.0.
- You want to switch machine providers without changing agent code.
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 | Omnara |
|---|---|---|
| Isolation | Firecracker micro-VM with its own guest kernel | Not published; depends on the attached machine (your own or a pool provider such as CreateOS) |
| Pause and resume | Pause saves disk, memory and CPU state; vCPU stops billing, memory and storage still bill | Agent state kept in a durable event log; pool machines deleted on release or after an idle period |
| Fork | Yes, fork a paused sandbox into many independent copies | Not published |
| Outbound network default | 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; the daemon connects outbound only |
| Concurrency | 1 / 5 / 20 / 30 by plan; paused sandboxes count toward the cap | Not published |
| Session length | No cap; idle auto-pause 60 s to 24 h, off by default | Agents can run indefinitely (vendor-stated) |
| Billing | Per second: $0.03616363 per vCPU-hour, $0.01159025 per GiB-hour, storage $0.0001584 per GB-hour; no egress fees, 50 GiB bandwidth budget per sandbox | Platform free; credits for models and for machines by active time; machine rates not published |
| SDKs and interfaces | TypeScript, Go, Python, Rust, C#, Java SDKs (all but TypeScript pre-1.0), CLI, MCP, REST | TypeScript SDK, CLI (npx omnara), REST API, MCP integrations |
| Self-host or BYOC | Enterprise only, onboarded by our team | Yes, Apache-2.0, in your own VPC |
Common Questions
Can Omnara run agents on CreateOS Sandbox?
Yes. Omnara lists CreateOS among the providers for its pooled machine capacity, alongside Daytona, Modal, Unikraft Cloud and others. Omnara runs the agent loop and keeps state in its event log, while tool calls execute on the attached machine.
Is Omnara a sandbox?
No. Omnara is an agent control plane that runs agents on machines you bring or on pooled capacity, and it does not publish its own isolation, sizes or machine prices. CreateOS Sandbox is the machine layer, with a Firecracker micro-VM per sandbox.
What does Omnara cost?
Omnara says the platform itself is free, and so is self-hosting. With Omnara credits you pay models at provider token rates and machines by active time, with machine rates not published. CreateOS Sandbox bills per second at published vCPU and memory rates.
