CreateOS vs SailSandbox Benchmark Comparison
CreateOS was faster in both shared sandbox benchmarks.
- Shared benchmarks
- 2
- Last run
- October 30, 2026
Scorecard
Median of each benchmark's primary metric; lower is better. Medians within 5% count as roughly even, and a benchmark gets no speed verdict when either provider completed fewer than 50% of runs.
Burst TTI
Run October 30, 2026Time from sandbox creation to the first successful command, with 100 sandboxes launched at the same time.
Time to interactive
CreateOS had a 15.8x lower median time to interactive (136ms vs 2.14s for Sail).
Median time to interactive over time
16 runs from August 7, 2026 to October 30, 2026.
DAX
Run October 30, 2026A real developer workload: install system packages, download Bun, clone the opencode repo, then run bun install and bun typecheck.
Total workload time
CreateOS had a 1.27x lower median total workload time (53.21s vs 67.34s for Sail).
Median total workload time over time
15 runs from August 14, 2026 to October 30, 2026.
Cost per DAX run
Each provider's DAX median total workload time (run October 30, 2026) multiplied by its published rate at the 8 vCPU / 16 GiB benchmark spec. Workload time excludes sandbox create and destroy, and subscription floors and included credits are not modeled.

Observed usage$0.015/used vCPU-hr + $0.008/used GiB-hr + $0.0007/GiB-hr NVMe — bills observed usage, not reservations (upper bound shown at full utilization). Plus $0.012 per L Sailbox creation. No charge while sleeping.
Source pricing pageMethodology
- One workload, every provider. The same script, payload, and model hit every provider, addressed the way its own API expects. Nobody gets a tuned or special path.
- Repeated on a schedule. Every suite runs many iterations per provider, automated on a recurring schedule, so results reflect steady state rather than one lucky request.
- Raw results published. Every run is committed as JSON to the public benchmarks repo, next to the code that produced it. Nothing is cherry-picked or held back.
- How this comparison is built. Each benchmark compares the two providers' medians; results within 5% count as roughly even. A comparison is published only when both providers completed at least 50% of runs in 2 or more shared benchmarks run in the last 30 days.
