CreateOS Sandbox vs Vultr
Vultr is a good fit for cheap, globally spread VMs and on-demand GPUs where servers run for hours or months. CreateOS Sandbox is the better fit for agent tasks measured in seconds or minutes, because Vultr charges at least one hour per server and keeps billing stopped ones. If you need AMD or NVIDIA GPUs, Vultr has them and CreateOS does not.

Vultr
Plans run from $0.005 per hour ($3.50 per month) for 1 vCPU and 512 MB up to $7.68 per hour for 192 vCPU and 1,536 GB, billed hourly with a one-hour minimum and a 672-hour monthly cap on most plans, as of 17 October 2026.
Where CreateOS Sandbox Fits Better
What CreateOS Sandbox brings to this matchup, with a plain note on where Vultr has the edge.
Seconds, not hours: no one-hour minimum per sandbox.
A paused sandbox drops the vCPU charge (memory and storage continue), while a stopped Vultr server keeps billing for reserved resources.
Memory-preserving pause and fork, which Vultr does not publish.
Where Vultr is strong
Simple hourly VMs from $0.005 per hour with bundled transfer and $0.01 per GB overage, plus a broad range of AMD and NVIDIA GPU plans.
Which to Pick
Pick CreateOS Sandbox if
- Agents spin up dozens of short tasks a day
- You need pause with memory between agent turns
- You want an HTTPS URL per sandbox without firewall groups
Pick Vultr if
- You need GPUs such as the L40S or MI355X
- You want a $5 per month VM that runs constantly
- You need up to 192 vCPU and 1,536 GB on one plan
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 | Vultr |
|---|---|---|
| Isolation | Firecracker micro-VM with its own guest kernel | Full VM |
| Create and destroy by API | Yes: REST API, CLI, SDKs for TypeScript, Go, Python, Rust, C# and Java (all but TypeScript pre-1.0), and an MCP server with create, exec and destroy tools | REST API v2, vultr-cli, Terraform and official API clients (not re-verified) |
| Memory snapshot (pause and resume) | Yes: pause saves disk, memory and CPU state; vCPU stops billing while paused, memory and storage still bill | No memory snapshot published; disk persists, snapshots exist (not re-verified); stopped servers keep billing |
| Fork | Yes: fork a paused sandbox into new, independent sandboxes | Not published |
| Outbound network controls | 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; Vultr firewall groups |
| Billing granularity | Per second while running, no minimums: $0.03616363 per vCPU-hour, $0.01159025 per GiB-hour | Hourly, one-hour minimum, capped at 672 hours a month on most plans (730 for GPU and VX1) |
| Largest size | 8 vCPU / 16 GB on Enterprise (8 / 8 Pro, 4 / 4 Beginner, 1 / 1 Free) | vx1-m-192c-1536gb: 192 vCPU, 1,536 GB |
| GPU | No GPU shapes | Yes, including NVIDIA L40S and AMD MI355X |
Common Questions
What is the minimum billing period on Vultr?
One hour. Vultr bills hourly with a one-hour minimum, capped at 672 hours a month for most plans, and stopped servers keep billing. CreateOS bills per second while a sandbox runs, with no minimum, at $0.03616363 per vCPU-hour.
How much bandwidth comes with a Vultr server?
It depends on the plan: vc2-2c-4gb includes 3 TB, the FAQ cites a 2 TB monthly free allotment, and overage is $0.01 per GB. CreateOS has no egress fees and gives each sandbox a 50 GiB outbound budget by default.
Does Vultr support memory snapshots for paused servers?
Vultr publishes no memory snapshot or fork, and a stopped server still bills for reserved resources. CreateOS pause stores memory, disk and CPU state, and a paused sandbox can be forked into independent copies.
