## Caveats

- No CPU/RAM allocation or overage environment-hour price published.
- Developer limit 5 concurrent and 100 included hours does not meet 50 concurrent / 8,800 hours.
- Artifact checkpoint is not evidence of a full memory VM snapshot; state/export support scoped to application workflow.
- Environment containment is not a documented hypervisor isolation type; leave isolation null/unknown.
- Enterprise unlimited claims are contractual, not an entitlement on $29 plan.
- Native billing cannot be reduced to a 4-vCPU/8-GiB price. No matching engine sizes, by design.
- Included environment-hours and concurrency are enforced as account limits: the API returns HTTP 403 when the account usage/concurrency limit is reached. No overage or pay-as-you-go rate is published, so usage stops at 5 h (Free) / 100 h (Developer) per month.
- Sandboxes have no external network access from the execution worker; terminal/browser/package-manager windows are blocked. File transfer is capped at 4 MiB per file; checkpoint workspace/bundle at 256 MiB; recordings at 512 MiB / 6 h.

## Gotchas

- No CPU/RAM allocation or overage environment-hour price published.
- Developer limit 5 concurrent and 100 included hours does not meet 50 concurrent / 8,800 hours.
- Artifact checkpoint is not evidence of a full memory VM snapshot; state/export support scoped to application workflow.
- Environment containment is not a documented hypervisor isolation type; leave isolation null/unknown.
- Enterprise unlimited claims are contractual, not an entitlement on $29 plan.

## Required worked example

4 vCPU / 8 GiB, 50 concurrent × 8 h/day × 22 days = **8,800 instance-hours**, 30% CPU, 50 GiB retained snapshots and 100 GiB egress.

**Sales quote required.** Neither 1-concurrent Free nor 5-concurrent Developer satisfies 50. Hardware size, 8,800-hour overage, retained artifacts and egress are not independently priced; do not multiply $29 by ten accounts or imply unapproved account pooling.
