Frequently Asked Questions

CloudRig uses a pay-as-you-go credit system. You add credits to your account, then choose a GPU plan. A top-up can be any amount from €1 to €20,000, or its equivalent in the currency you pick at the day's rate (US dollars included), with the maximum rounded down to a round figure so it never exceeds €20,000. In your selected currency that is $1.12–$22,320. Billing is per-second while your machine is running. When you stop your machine, billing stops instantly. There are no subscriptions, contracts, or hidden fees.

You are charged per second only while your machine is in the Running state. Stopped machines do not incur charges. Credits are deducted from your balance in real time. You can monitor your spending from the Billing page in your dashboard.

We accept Visa and Mastercard credit and debit cards, and Multibanco (EUR) or BLIK (PLN) where they are shown at checkout. Card details go over an encrypted (HTTPS) connection to our payment processor, which takes the payment.

Unused credits can be refunded within 14 days of purchase. If a running machine stops working because of a fault on our platform or its host, email us the machine ID and we credit the time you lost. Contact support@cloudrig.space for refund requests.

If your credit balance reaches zero while a machine is running, the machine is stopped automatically. Your files and machine state are kept for 24 hours, giving you time to add credits and resume. We also email a low-balance warning once a day while a machine is running on a low balance, so keep an eye on your balance.

We offer four tiers: Starter (RTX A4000 or RTX 4060 Ti, 16 GB VRAM) at $1/hr, Standard (RTX 4090, 24 GB VRAM) at $1.50/hr, Pro (L40S, 48 GB VRAM) at $2.25/hr, and Power (A100 80GB) at $3/hr. All plans include SSD storage, multiple vCPUs, and full admin access.

Most machines are ready in a few minutes. Deployment time can vary depending on region availability and the GPU tier you select. Once running, you receive connection credentials immediately in your dashboard.

Yes, for 24 hours. When you stop a machine, your files and installed packages are kept. Restart within that window and everything is as you left it. After 24 hours the machine and its data are deleted, so copy anything important off the machine before then.

Ubuntu Linux, with NVIDIA drivers, CUDA and PyTorch pre-installed and root access. Install anything else with apt or pip. There is no Windows and no graphical desktop.

Your machine's page shows the SSH command and a button that opens Jupyter in your browser. Use SSH for a terminal and file transfers (scp, rsync), and Jupyter for notebooks.

Very little for a terminal or notebooks — any stable connection works. A faster connection helps when you upload large datasets or download results.

Yes. Open Jupyter in your mobile browser, or use any SSH app. A keyboard helps for longer sessions.

No. CloudRig machines are Linux compute boxes without a graphical desktop or game streaming, so they are not suitable for gaming or VR.

Anything that runs on Linux with an NVIDIA GPU: AI and machine learning (PyTorch, TensorFlow, ComfyUI, Ollama, vLLM), command-line rendering (Blender Cycles), and general development. The Power tier with the A100 80GB is for the largest models.

First, check that you have enough credit. Then try a different GPU tier in case your selected tier is temporarily out of capacity. If a machine does not start within the time limit, the deploy is cancelled and you are not charged. If the issue persists, contact support@cloudrig.space.

Make sure the machine shows Running in your dashboard, and copy the SSH command exactly as shown on the machine's page. Check that your network or VPN does not block outgoing SSH. If you still cannot connect, stop and restart the machine from your dashboard.

Run nvidia-smi in a terminal. If it lists your GPU, check that your software was installed with CUDA support. If nvidia-smi fails or shows no GPU, stop and redeploy the machine or contact support.
