GlobalStacks vs Modal

Modal is a powerful serverless and GPU compute platform. GlobalStacks is designed for teams that want sandbox fleets on infrastructure they operate directly.

Modal Sandboxes

When Modal fits

Best fit: ML-heavy workloads, GPU-backed agent tools, and teams already using Modal's serverless model.
Pricing: Sandbox CPU is $0.00003942 per physical core-second, where one physical core is listed as a 2 vCPU equivalent. Sandbox memory is $0.00000672 per GiB-second.
GPU: Standard GPU pricing includes H100 at $0.001097 per second, equal to about $3.95 per hour, and RTX PRO 6000 at $0.000842 per second, equal to about $3.03 per hour.
Important tradeoff: If your main requirement is a mature serverless GPU platform, Modal has a deep product surface.

GlobalStacks

When to choose GlobalStacks

Use GlobalStacks when sandboxes need private-network placement, host-agent control, owned clusters, distributed volumes, and a path from self-hosted capacity to managed GPU capacity later.

Self-hosted pricing

$1 per self-hosted cluster per month, plus the infrastructure you already operate.

Managed pricing

Managed clusters use transparent usage meters: $0.0504 per vCPU-hour, $0.0162 per GiB memory-hour, $0.000108 per GiB storage-hour, H100 at $3.95 per GPU-hour, and RTX PRO 6000 at $3.03 per GPU-hour where available.

Decision guide

Pick the model that matches your workload.

Choose GlobalStacks when sandbox infrastructure needs to run across your own hosts, private networks, storage systems, and regional capacity choices. Self-hosted clusters keep the platform fee low while your team controls the underlying machines.

Use managed GlobalStacks clusters when you want the same control-plane model without operating the capacity yourself.
