CreateOS Sandbox vs MIOSA
Pick MIOSA if you are building a multi-tenant AI app builder and want sandboxes, deploys, managed Postgres and Redis and per-end-user billing from one vendor. Pick CreateOS Sandbox if you mainly need sandboxes and care about cost: lower per-hour rates, no egress fees, paid plans from $10 a month instead of a $500 minimum, and an EU region.

Where CreateOS Sandbox Fits Better
What CreateOS Sandbox brings to this matchup, with a plain note on where MIOSA has the edge.
Lower list rates: $0.03616363 per vCPU-hour and $0.01159025 per GiB-hour against MIOSA's $0.0454 and $0.0146.
No per-GB egress fee (50 GiB bandwidth budget per sandbox), where MIOSA charges $0.04 per GB.
Paid plans start at $10 to $50 per month; MIOSA's Business plan is a $500 monthly minimum.
An eu region alongside us; MIOSA's regions are all in the US.
Where MIOSA is strong
MIOSA goes well past the sandbox into the rest of an agent product: previews, immutable deploys, managed Postgres and Redis, per-end-user quotas and usage rollup for white-label resale, and an observe-then-enforce egress allowlist that swaps secrets in at the proxy.
Which to Pick
Pick CreateOS Sandbox if
- Your monthly spend is below MIOSA's $500 Business minimum.
- Your agents move a lot of data out and you want no per-GB egress price.
- You need sandboxes hosted in the EU.
Pick MIOSA if
- You resell agent environments to your own customers and need per-end-user quotas and usage attribution.
- You want to fork a running sandbox without pausing it first.
- You need sandboxes up to 16 vCPU / 32 GiB, or GUI computers up to 32 vCPU / 128 GiB.
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 | MIOSA |
|---|---|---|
| Isolation | Firecracker micro-VM with its own guest kernel, root filesystem and network identity | Firecracker microVM on the standard runtime; a second runtime, SOMA, is in early access without pause or snapshots |
| Pause and resume | Saves disk, memory and CPU state; vCPU stops billing while paused, memory and storage still bill | Pause keeps memory and processes for up to 30 minutes, then acts as a stop; disk persists by default |
| Fork | Fork a paused sandbox into many independent copies, each with its own id and IP | Fork a running sandbox through a copy-on-write checkpoint; restore a snapshot into a new sandbox |
| 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 | Open, in audit-only mode; enforceable allowlist by host, wildcard or CIDR with method and path scoping |
| Inbound access | Closed by default; opt-in public HTTPS URL, plus API-authenticated shell and port tunnels | No inbound by default; exposed ports go through the MIOSA proxy with preview and share tokens; SSH via CLI |
| Largest size | 8 vCPU / 16 GB on Enterprise (Pro 8 vCPU / 8 GB, Beginner 4 / 4, Free 1 / 1) | 16 vCPU / 32 GiB / 80 GiB disk on Enterprise (Developer 2 / 4, Business 8 / 16) |
| Concurrency | Free 1, Beginner 5, Pro 20, Enterprise 30; paused sandboxes count toward the cap | Developer 10, Business 250, Enterprise 500 running sandboxes |
| Session length | No lifetime cap; optional idle auto-pause from 60 s to 24 h, off by default | timeout_sec 1 to 86,400 (default 3,600); always_on disables the timeout |
| Billing | Per second: $0.03616363/vCPU-hr, $0.01159025/GiB-hr, storage $0.0001584/GB-hr; no egress fees, 50 GiB bandwidth budget per sandbox | Per second: $0.0454/vCPU-hr, $0.0146/GiB-hr, $0.04/GB egress; Business $500 and Enterprise $1,000 monthly minimums |
| SDKs and interfaces | TypeScript, Go, Python, Rust, C#, Java (all but TypeScript pre-1.0), CLI, MCP, REST | TypeScript, Python, Go, Rust, Elixir and Java SDKs, CLI, MCP server, REST with OpenAPI |
Common Questions
What is the minimum monthly spend on MIOSA?
MIOSA's paid plans are monthly minimums credited to usage: $500 for Business and $1,000 for Enterprise, with a free Developer plan carrying a $10 one-time credit. CreateOS Sandbox paid plans run from $10 to $50 per month on Beginner, and the Free plan needs no card.
How long does a paused MIOSA sandbox keep its memory?
Up to 30 minutes, after which the pause behaves as a stop, and memory checkpoints expire after 72 hours. CreateOS Sandbox pause writes disk, memory and CPU registers to durable object storage; memory and storage keep billing while the vCPU charge stops.
Does MIOSA charge for egress?
Yes, MIOSA lists egress at $0.04 per GB. CreateOS Sandbox has no per-GB egress fee; each sandbox gets a 50 GiB outbound bandwidth budget, and recharging past it uses account credit at a rate the docs do not publish.
Can MIOSA fork a sandbox while it is running?
Yes, MIOSA forks a running sandbox through a copy-on-write checkpoint. CreateOS Sandbox forks only from a paused sandbox: you pause the source, then create as many independent children as you need, and the source stays paused and untouched.
