MIOSA vs Vercel Sandbox
Vercel Sandbox and MIOSA both run AI-generated code in ephemeral compute. This page compares them on the independent ComputeSDK benchmark and on the capabilities MIOSA documents.
What Vercel Sandbox is
Vercel Sandbox runs ephemeral compute for AI agents as part of the Vercel platform, described in its public documentation at vercel.com/docs/vercel-sandbox (as of October 2026). Its main draw is tight integration with Vercel’s deploy and hosting surface.
Measured performance
The independent ComputeSDK benchmark runs the same workload against every provider.
| Metric | MIOSA | Vercel Sandbox | As of |
|---|---|---|---|
| Burst startup, median time-to-interactive | 117.93 ms (#1 of 30) | 665.97 ms (#10) | 2026-10-09 |
| DAX full build, total time | 39.3 s (#1 of 19) | 69.7 s | 2026-08-28 |
| DAX full build, latest run | no result | 80.0 s | 2026-10-09 |

Where MIOSA differs
These capabilities are documented for MIOSA on this site:
- Persistent computers with a desktop alongside sandboxes. See Computers.
- A standalone deploy surface that is not tied to one host: immutable versions, releases, and rollback. See Deployments.
- White-label platform with your domains and tenants. See White-label setup.
- Managed data with connection injection. See Data.
- Regions and your own hardware. See Regions and OpenComputers.
When to choose each
- Choose Vercel Sandbox if you are already all-in on Vercel and want the sandbox and the deploy surface under one account and one bill.
- Choose MIOSA if you want a platform-independent runtime for sandboxes, computers, agent runs, deployments, and data, with a branded multi-tenant surface and the measured startup figures above.
