CreateOS Sandbox vs OmniRun
Pick OmniRun if you want to run Firecracker sandboxes on a KVM machine you already own, free under Apache-2.0, or need managed hosting kept in Finland. Pick CreateOS Sandbox if you want to sign up today on public per-second rates, with documented pause, resume and fork. Both put each sandbox in a Firecracker micro-VM with its own kernel.
Pricing at a Glance
CreateOS rates verified 17 October 2026. OmniRun pricing as published on 26 October 2026. Rates billed per GB rather than per GiB, or as bundled sizes, are quoted as published rather than converted.
CreateOS Sandbox
- Compute
- $0.0362 /vCPU-hr
- Memory
- $0.0116 /GiB-hr
OmniRun
OmniRun's managed page says limits and price are agreed with each team, while an April 2026 OmniRun blog post quotes a per-hour overage rate, so no figure is given here; self-hosting is free under Apache-2.0, as of 26 October 2026.
Where CreateOS Sandbox Fits Better
What CreateOS Sandbox brings to this matchup, with a plain note on where OmniRun has the edge.
Public per-second rates ($0.03616363 per vCPU-hour, $0.01159025 per GiB-hour) and a self-serve Free plan, where OmniRun's managed terms are negotiated per customer.
Documented pause that saves disk, memory and CPU state, plus fork from a paused sandbox into many copies.
Two managed regions, eu and us, against OmniRun's Finland-only managed hosting.
CreateOS is SOC 2 Type II and ISO 27001 certified, with reports available under NDA.
Where OmniRun is strong
OmniRun lets you run the entire stack, microVM isolation included, on one KVM machine you already own under Apache-2.0, and its managed option keeps data on EU hosts.
Which to Pick
Pick CreateOS Sandbox if
- You need self-serve signup and a published rate card today.
- Your agents need to pause with memory intact and fork from that point.
- You want SDKs beyond TypeScript and Python, such as Go, Rust, C# or Java.
Pick OmniRun if
- You want to self-host the full stack on your own x86_64 KVM host at no license cost.
- Your data must stay on EU hosts and you are fine negotiating a managed contract.
- You already call e2b-style REST endpoints and want a compatible API.
Head-to-Head Comparison
Every dimension side by side, checked on 26 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.

|---|---|---|
| Isolation | Firecracker micro-VM with its own guest kernel | Firecracker micro-VM (KVM) with its own kernel, disk and network namespace |
| Pause and resume | Pause saves disk, memory and CPU state; vCPU stops billing, memory and storage still bill | User-facing pause, resume or snapshot API not published; sandboxes start from template memory snapshots |
| 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 | Networking off in base templates; internet can be switched on per sandbox; HTTPS allowlists through an opt-in SNI proxy |
| Inbound access | Closed by default; opt-in public HTTPS URL | Preview URL per exposed port; auth not published |
| Concurrency | 1 / 5 / 20 / 30 by plan; paused sandboxes count toward the cap | Agreed per customer on the managed service; numbers not published |
| Session length | No cap; idle auto-pause 60 s to 24 h, off by default | Per-sandbox timeout (examples use 300 s); default and maximum not published |
| 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 | Managed: no public price list; self-host: free |
| SDKs and interfaces | TypeScript, Go, Python, Rust, C#, Java SDKs (all but TypeScript pre-1.0), CLI, MCP, REST | TypeScript and Python SDKs, e2b-style REST API, omnictl CLI; MCP not published |

Common Questions
Is OmniRun open source?
Yes. OmniRun's server, in-VM agent, gateway, CLI and SDKs are under Apache-2.0, and self-hosting needs one x86_64 Linux host with KVM, with bare metal recommended. CreateOS Sandbox offers self-hosting only to enterprise customers, onboarded by our team.
How much does OmniRun's managed service cost?
OmniRun's managed page says limits and price are agreed with each team, and its own blog quotes a different per-hour figure. CreateOS Sandbox bills per second at $0.03616363 per vCPU-hour and $0.01159025 per GiB-hour, the same rate on every plan, as of 26 October 2026.
Where does OmniRun host managed sandboxes?
OmniRun's managed hosts are in Finland only, and self-hosted installs run wherever you put them. CreateOS Sandbox runs in two managed regions, eu and us, picked with the region field when you create a sandbox.
Does OmniRun start sandboxes from snapshots?
Yes. OmniRun creates each sandbox by restoring a template memory snapshot with a copy-on-write disk clone, but a user-facing pause or snapshot API is not published. In CreateOS Sandbox you can pause a running sandbox yourself and fork it.
