Sandboxer vs Runpod

Runpod rents GPU Pods (containers) by the second across 30+ regions, plus serverless and clusters. Sandboxer is full microVMs without GPUs. Pick Runpod for GPUs; pick Sandboxer when you need a full VM with Docker and KVM.

Checked against Runpod's public docs on October 24, 2026. Sources are linked in the table and listed below.

At a glance

Sandboxer and Runpod compared
Capability	Sandboxer	Runpod
Isolation	microVM Cloud Hypervisor, its own kernel	Container Pods run a container image; the docs do not name a sandbox technology.
Full Linux with root	Ubuntu 24.04, sudo, systemd	partial Docs promise full control of the environment inside the container; root is not stated explicitly.
Docker inside	Preinstalled	Docs say you cannot run your own Docker instance or Docker Compose on Pods.
Nested virtualization (/dev/kvm)
Pause and resume with memory	Running processes come back	The container disk is lost on stop; only the volume disk persists.
Fork a sandbox	Copy-on-write disk copy that boots fresh
HTTPS URL per port	Private with a token, or public	A web proxy exposes HTTP services; TCP is supported, UDP is not.
Longest session	No limit on paid plans Auto-stop is up to 30 days or off
Billing	Per second, flat rate per size Stopped sandboxes are free	Per second for Pods; storage billed separately
GPUs		Community and Secure Cloud tiers; B300 is among the listed GPUs.
Self-host or open source
Regions	US East (Virginia) and EU Central (Finland)	30+ regions Regions are not named on the price page.

= not documented publicly.

Where Runpod is strong

Per-second Pod billing across Community and Secure Cloud tiers.
Large GPU range up to B300, plus serverless and clusters up to 64 GPUs.
30+ regions.
Network volumes attachable across Pods and serverless endpoints.

Where Sandboxer differs

Runpod Pods are containers without Docker-in-Docker; Sandboxer sandboxes are full VMs with Docker and nested KVM.
Stopping a Pod discards the container disk; Sandboxer stop keeps memory and disk.
Runpod has GPUs; Sandboxer has none.
Runpod has no Windows support; neither does Sandboxer.

Pick Runpod if

You need low-cost access to a wide range of GPU types.
You want serverless GPU endpoints.
You need many regions.

Pick Sandboxer if

You need a CPU sandbox with Docker, nested KVM and systemd that stops and resumes with running processes intact, and you do not need GPUs.
You want coding agents (Claude Code, Codex and others) preinstalled and driven through a prompt API with streamed events.
You want per-second billing with stopped sandboxes costing nothing and a flat $20 to $2000 monthly plan whose dollars return as machine time.
