Sandboxes are in public preview and available on the Starter, Pro and Scale plans. They run on the same instance types and per-second prices as other Koyeb services.
The default instance type for a sandbox is micro (0.5 vCPU, 512 MB, $0.000002/s). Sizes with fractional vCPU (nano, micro, eco-nano, eco-micro, eco-small) are not listed here.
Eco instance types are offered in Washington, D.C., Frankfurt and Singapore only.
Bandwidth above the included 1 TB costs $0.02/GB in EU/US and $0.04/GB in Asia (pricing page); the pricing FAQ says outbound bandwidth is not yet charged and quotes $0.04/GB once billing begins.
GPU use in sandboxes is stated in the launch post; GPU prices come from the pricing page (per hour). Multi-GPU instance types (2x, 4x, 8x) are not listed here.
SOC 2 and ISO 27001 are listed under the Enterprise plan on the pricing page.
The default image includes Mistral Vibe, Codex, Gemini CLI and OpenCode.
