Compute Capacity,
Precisely Allocated.

Rent the infrastructure you need, from a development workspace to an entire Kubernetes cluster. Choose metered use or a listed commitment and review the complete price before starting.

Compute³ is a cloud-native marketplace for compute infrastructure. Rent GPUs, CPUs, Kubernetes capacity, AI workstations, and clusters from providers around the world, with transparent pricing and enterprise-grade orchestration.

Use Cases

Compute for the Workloads Providers Actually Run

Interactive AI workstations

Launch SSH, VS Code, and Jupyter-ready workspaces on provider GPUs without reserving an entire cluster when a single node is enough.

Kubernetes namespaces

Give teams a bounded namespace with quota, service-account access, and familiar kubectl workflows for model serving, batch jobs, and experiments.

Dedicated GPU nodes

Reserve the whole machine when workloads need predictable local disk, full GPU visibility, or direct access to the node capacity.

Multi-node clusters

Rent coordinated capacity for distributed training, internal platforms, test environments, and infrastructure teams that already operate on Kubernetes.

Provider monetization

List idle lab, office, datacenter, or workstation capacity with visible pricing, hardware reports, validation status, and uptime history.

Heterogeneous hardware labs

Expose NVIDIA, AMD, CPU-only, and specialized AI workstation capacity through one control plane instead of forcing every machine into one shape.

Built on Kubernetes

Infrastructure Professionals Already Trust

Everything in Compute³ is built on Kubernetes.

  • Not Kubernetes-inspired.
  • Not Kubernetes-compatible.
  • Kubernetes-native.

This allows workloads to run on mature, battle-tested infrastructure patterns already trusted by enterprises, research organizations, AI teams, and cloud providers.

Compute³ is designed around the same orchestration principles used to operate modern large-scale infrastructure.

WORKLOADS (TENANT BOUNDARY)COMPUTE³ ORCHESTRATIONHETEROGENEOUS HARDWARE PROVIDERS

Secure by Default

Your Infrastructure Stays Private

No public IPs. No port forwarding. No firewall gymnastics.

Joining Compute³ does not require exposing your infrastructure to the internet.

All communication between provider nodes and the platform occurs through secure WireGuard tunnels established outbound from the provider network.

Providers do not need:

  • Static IP addresses
  • Publicly routable IPs
  • Port forwarding
  • Firewall rule changes
  • Complex networking configuration

A node can be onboarded from a home lab, office, datacenter, or cloud environment with minimal networking requirements.

Compute³ securely connects workloads to infrastructure while keeping provider networks isolated and private.

Rent Exactly What You Need

From a Single Workspace to an Entire Cluster

Infrastructure should adapt to the workload. Compute³ supports multiple consumption models:

  • Development workspace with SSH access
  • Dedicated Kubernetes namespace
  • Dedicated node
  • Multi-node cluster

Users can consume exactly the amount of infrastructure they need. No oversized instances. No wasted resources. No paying for capacity that sits idle.

Precise allocation means better utilization and lower costs.

CPU-only systems
Mixed vendor configurations

Hosts Stay in Control

The provider decides what resources are available, what can be rented, capacity limits, availability schedules, and tenant permissions.

Compute³ provides orchestration while preserving provider control.

Hardware Without Artificial Limits

Bring the Hardware You Actually Own

Compute³ is designed around real-world infrastructure rather than a narrow list of approved configurations.

Providers are not forced into artificially restricted hardware profiles. Modern infrastructure is heterogeneous. The platform embraces that reality.

Transparent by Design

No Black Boxes

Review onboarding status, benchmark results, allocations and recorded earnings throughout the provider lifecycle. Renters see the complete rental price before accepting.

Provider Docs

Host Setup That Matches ComputeCubed

Provider setup is documented publicly and adapted to the ComputeCubed control plane. It does not require public IP addresses, per-GPU port forwarding, or a separate marketplace daemon.

The host flow is based on a one-time join command, outbound WireGuard connectivity, k3s-agent registration, hardware collection, validation, then listing controls for nodes and clusters.

Read host setup docs
01

Prepare the Linux node

Use a server-oriented Linux install, keep firmware and GPU drivers stable, and verify the hardware locally before onboarding.

02

Create or select a cluster

ComputeCubed joins provider machines to a managed k3s control plane, so each node inherits the cluster GPU type and rental modes.

03

Run the one-time join command

The command installs required WireGuard tools, creates an outbound tunnel, starts k3s-agent, and registers hardware with the platform.

04

Review validation and publish

Hardware collection, network checks, disk tests, GPU checks, and pricing controls determine when a node or cluster is ready to list.

Provider Linux

Recommended Linux Distributions

Start with a server-oriented Linux installation and working GPU drivers. Ubuntu Server is our recommended starting point for your first node. Other distributions may also work when they meet the host requirements.

Ubuntu Server

22.04 LTS · 24.04 LTS

Recommended starting points for preparing your first provider node.

Why Compute³

A Modern Approach to Compute Infrastructure

Kubernetes-native

Built entirely on standard K8s primitives for enterprise-grade orchestration.

Secure Connectivity

Outbound-only WireGuard tunnels ensure provider networks remain completely private.

No Network Hassle

No public IPs required. No port forwarding. Seamless onboarding from anywhere.

Precise Allocation

From a single namespace to multi-node clusters, rent exactly what the workload demands.

Hardware Flexibility

Broad compatibility across GPU vendors and configurations. Mixed topologies supported.

Provider Autonomy

Granular control over sharing policies, schedules, and resource limits.

Transparent Metrics

Open benchmarking and clear visibility into node performance and allocation status.

Transparent Pricing

Hosts set their earnings price. Renters see the complete rental price, including marketplace markup, before accepting.

Enterprise Foundations

Designed for production workloads, AI teams, and serious infrastructure operations.

Pricing

Simple and Transparent

Know the price before you rent.

Rental charges, host earnings and Stripe transfers are recorded separately.

Set the price you want to earn for your resources. ComputeCubed adds a markup that can vary by listing. Renters review the complete price before accepting, and accepted prices stay fixed for that rental and its recurring periods.

A successful €10 top-up adds exactly €10 to Rental Balance; €10 is the minimum. ComputeCubed covers payment-processing and platform-billed Stripe costs. Hosts receive their full eligible earnings in their Stripe account; Stripe may charge that account directly for bank payouts.

  • No listing fees
  • No host earnings commission
  • No ComputeCubed withdrawal fee

What providers earn and what renters pay should never be a mystery.
