Sandboxer vs CreateOS Sandbox

CreateOS Sandbox, from NodeOps, runs each sandbox as a Firecracker microVM that can pause to durable storage, resume on request and be cloned. It offers US and EU regions and no GPUs. Sandboxer offers a full Ubuntu VM with Docker and nested KVM; CreateOS fits teams that want per-second CPU/RAM pricing.

At a glance

Sandboxer and CreateOS Sandbox compared
Capability	Sandboxer	CreateOS Sandbox
Isolation	microVM Cloud Hypervisor, its own kernel	Firecracker microVM Own kernel, root filesystem and network identity.
Full Linux with root	Ubuntu 24.04, sudo, systemd
Docker inside	Preinstalled
Nested virtualization (/dev/kvm)
Pause and resume with memory	Running processes come back	Pause snapshots full state (memory and disk); the docs do not explicitly say processes keep running after resume.
Fork a sandbox	Copy-on-write disk copy that boots fresh	Forking clones a paused sandbox into a byte-identical copy with its own id and IP.
HTTPS URL per port	Private with a token, or public	Public ingress exposes an HTTP service on a per-sandbox HTTPS URL.
Longest session	No limit on paid plans Auto-stop is up to 30 days or off	no limit Runs until destroyed or paused; auto-pause is off by default (60 s to 24 h).
Billing	Per second, flat rate per size Stopped sandboxes are free	per second, vCPU + RAM + storage $0.0362/vCPU-h, $0.0116/GiB-h, $0.000158/GB-h; paused sandboxes pay memory and storage only; no egress fees.
GPUs		None offered.
Self-host or open source		partial Enterprise customers only, onboarded by the CreateOS team.

Two regions, US and EU.
Unmetered egress.
Mounts S3-compatible buckets and has a private p2p network with WireGuard access.

Where Sandboxer differs

CreateOS offers US and EU regions; Sandboxer runs in us-east and eu-central and has no SLA during early access.
The CreateOS docs do not state root, Docker or nested KVM; Sandboxer has all three.
Max size on Pro is 8 vCPU / 8 GB with concurrency 20; Sandboxer plans set concurrency 100 to 2000.
CreateOS list price for 4 vCPU / 8 GB is about $0.24/h; Sandboxer default is $0.036/h.

Pick CreateOS Sandbox if

You need an EU region.
You want idle auto-pause that wakes on an HTTP request.
You want enterprise self-hosting of the data plane.

Pick Sandboxer if

You need Docker and nested KVM in a full Ubuntu VM.
You want coding agents preinstalled and driven via a prompt API.
