Compare
MIOSA vs Modal
Modal and MIOSA both run compute for AI products. This page compares them on the independent ComputeSDK sandbox benchmark and on the capabilities MIOSA documents.
MIOSA 
Modal What Modal is
Modal is a serverless cloud platform for running compute for AI workloads, including sandboxed containers, described in its public documentation at (modal.com/docs, as of October 2026).
Measured performance
The independent ComputeSDK benchmark runs the same workload against every provider. That is the only apples-to-apples number here.
| Metric | MIOSA | Modal | As of |
|---|---|---|---|
| Burst startup, median time-to-interactive | 57.09 ms (#1 of 32) | 1070.58 ms (#17) | 2026-10-23 |
| DAX full build, 2026-08-28 | 39.3 s (#1 of 19) | 97.7 s | 2026-08-28 |
| DAX full build, 2026-10-23 | 38.8 s (#3 of 22) | 82.3 s (#16) | 2026-10-23 |
Source: ComputeSDK, via our benchmark page. Burst startup is the time from a create request to the first successful command inside a fresh sandbox, under 100 concurrent creates. Where a run is not listed, the provider did not appear in that run.
Capabilities side by side
Each Modal answer comes from Modal’s own documentation or pricing page, linked in the last column, fetched on 2026-10-23. Each MIOSA answer links the page that documents it. “Not documented” means the vendor’s docs do not say, not that the feature is missing.
| Capability | MIOSA | Modal | Source |
|---|---|---|---|
| Isolation | Firecracker microVM by default | gVisor, or a VM runtime | Modal docs |
| Sandbox lifetime | Idle timeout, 1 hour by default and up to 24 hours, extendable; computers persist | 5 minutes by default, up to 24 hours | Modal docs |
| Pause, snapshots, forks | Yes: pause and resume, snapshots, restore and fork | Snapshots; no pause and resume | Modal docs |
| Full Linux desktop and computer use | Yes, Computers | As an example (VNC in a VM sandbox), not a product | Modal docs |
| Public preview URL for a port | Yes | Yes, tunnels | Modal docs |
| Deploy to a production URL | Yes, Services and Docker Host, with releases and rollback | Not for sandboxes; apps deploy with modal deploy | Modal docs |
| Managed databases | Postgres, MySQL, Redis, MongoDB, Qdrant | Not documented | Modal docs |
| SDKs | TypeScript, Python, Go, Elixir, Java, Rust | Python, JavaScript, Go | Modal docs |
| CLI | Yes | Yes | Modal docs |
| MCP server | Yes, hosted | Not documented | Modal docs |
| Bring your own cloud | Yes, AWS and Google Cloud | Not documented | Modal docs |
| Billing | Per second while running, one price per size | Per second, per core and GiB | Modal docs |
| Regions | us-east, us-west, us-mia | Many, at a price multiplier; region routing does not apply to sandboxes | Modal docs |
Where MIOSA differs
These capabilities are documented for MIOSA on this site:
- Persistent computers with a full Linux desktop, not only headless sandboxes. See Computers.
- Deployments and Docker Host, so a machine becomes a versioned URL or a containerized app. See Deployments.
- White-label platform, so your customers see your brand and domains. See White-label setup.
- One interface for everyone: MCP, a CLI, and six SDKs. See MCP, CLI, SDKs.
- Managed data with connection injection: Postgres, MySQL, Redis, MongoDB, Qdrant. See Data.
- Regions and OpenComputers for machines you own. See Regions and OpenComputers.
When to choose each
- Choose Modal if you need serverless GPU compute, model serving, or general batch infrastructure alongside sandboxes.
- Choose MIOSA if your product is agent- and app-shaped: sandboxes, full computers, agent runs, deployments, managed data, and a white-label surface, with the measured startup figures above.
