Account & Getting Started

New accounts receive a $15 signup bonus when you make your first deposit of at least $5. You also get a $1 bonus for verifying your email address — that’s up to $21+ to get started.
Yes. Email verification is required to receive the $1 email bonus and to be eligible for the $15 signup bonus on your first deposit. You can resend the verification email from Account Settings.
Nova Cloud accepts:
  • Credit and debit cards via Stripe (Visa, Mastercard, Amex)
  • Cryptocurrency via Crypto.com Pay — coming soon
The minimum deposit is $5 and the maximum is $1,000 per transaction.
Not at this time. Cryptocurrency payments via Crypto.com Pay are coming soon — once available, you’ll be able to pay with BTC, ETH, USDC, and more without a credit card.
Go to Account Settings in the console. You can enable TOTP-based 2FA using an authenticator app like Google Authenticator or Authy. Backup codes are provided in case you lose access to your authenticator.

​
Instances & GPUs

Nova Cloud currently offers:
  • NVIDIA RTX 5090 — 32GB vRAM, latest generation
  • NVIDIA RTX 4090 — 24GB vRAM, excellent value
  • NVIDIA RTX PRO 6000 — 48GB vRAM, professional grade
You can browse current availability and pricing on the console dashboard.
When creating an instance, you can choose from:
  • Ubuntu 22.04 Base Image — Clean install with NVIDIA drivers
  • Ubuntu 24.04 Base Image — Latest Ubuntu with NVIDIA drivers
  • Stable Diffusion (A1111) + Jupyter — Pre-configured for image generation
  • ComfyUI + Jupyter — Node-based image generation workflow
  • Linux Desktop + Jupyter — Full desktop environment in browser
  • Stop pauses the instance. GPU billing stops, but storage billing continues at a small rate. Your data is preserved and you can start the instance again later.
  • Destroy permanently deletes the instance and all its data. All billing stops immediately. This action is irreversible.
No. The rental type is set when the instance is created and cannot be changed. To switch types, destroy the current instance and create a new one with the desired rental type.The exception is reserved instances — when the reservation expires, the instance automatically converts to on-demand billing.
When an interruptible instance is preempted:
  1. Running processes are stopped (like a power-off)
  2. Your data on disk is preserved
  3. The status changes to Interrupted in the dashboard
  4. If auto-restart is enabled (on by default), the instance automatically restarts when a GPU becomes available
  5. The system checks for available capacity every 60 seconds
You are not charged for GPU time while interrupted. Save your work frequently and use checkpointing for training jobs.
Auto-restart is a setting for interruptible instances. When enabled, your instance will automatically restart when GPU capacity becomes available after an interruption. It’s enabled by default and can be toggled in the instance Configure menu. Auto-restart is disabled after 7 days without a restart.
Instance provisioning typically takes 1–10 minutes, depending on the template and current demand. You can monitor the status on the My Instances page — it will change from “Creating” to “Running” when ready.
Yes. Click the Configure button on any instance and set a custom label (up to 32 characters). This helps you identify instances when running multiple VMs.
The instance card on the My Instances page shows real-time metrics:
  • CPU usage (percentage)
  • RAM usage (percentage)
  • Disk I/O (data transferred)
  • Network (data transferred)

​
Billing & Pricing

Nova Cloud uses a prepaid credit system. Costs are deducted from your balance by the second while instances are running:
  • GPU cost — Based on GPU type, count, and rental type
  • Storage cost — Based on disk size, continues even when the VM is stopped
  • Network cost — $2 per TB of data transfer
See the Billing guide for full details.
When your balance hits zero:
  1. All running on-demand and interruptible VMs are stopped
  2. You receive a warning email
  3. A reminder email is sent 4 days later (72 hours before destruction)
  4. After 7 days, all stopped non-reserved VMs are permanently destroyed
Reserved instances are not affected — they continue running from their separate deposit balance. Enable auto billing to prevent this.
Auto billing automatically charges your saved credit card when your balance drops below a threshold. Configure it in Account Settings:
  • Threshold: $2, $5, $10, $25, or $50 (triggers the top-up)
  • Amount: $10, $25, $50, $100, or $250 (amount added)
You need a saved payment method to use this feature.

You pay an upfront deposit covering the reservation period. See the Rental Types guide for details.
You can cancel a reservation at any time, but a 25% early termination fee is applied to the remaining deposit balance. 75% is refunded to your credit balance.
Yes. Go to Account Settings → Billing and you can download PDF invoices for any billing period. Both credit (payment) and debit (usage) invoices are available.
GPU billing stops when an instance is stopped. However, storage billing continues at the allocated disk rate. To stop all billing, destroy the instance.

​
Connectivity & Ports

There are two ways:
  • SSH — Terminal access using ssh ubuntu@<your-vm-ip>. Available for all instances.
  • WebUI Portal — Browser-based access for templates that include a WebUI (Stable Diffusion, ComfyUI, Linux Desktop). Access it by clicking Connect on your instance.
See the Connecting guide for step-by-step instructions.
All ports except SSH (port 22) are closed by default for security. You need to open ports using UFW (the firewall):
sudo ufw allow 8888/tcp
Also make sure your service is bound to 0.0.0.0 (not 127.0.0.1). See the Instance Ports guide for details.
The WebUI portal is a Cloudflare-secured browser gateway that gives you access to web applications running inside your instance without opening ports. It’s available for instances created with the Stable Diffusion, ComfyUI, or Linux Desktop templates. Access it by clicking Connect on your instance.
The default username is ubuntu for all instances.
Yes. SSH tunneling is a secure alternative that forwards traffic through your SSH connection:
ssh -L 8888:localhost:8888 ubuntu@<your-vm-ip>
Then access the service at http://localhost:8888 in your browser. See the Instance Ports guide for details.

​
Security & API

You can upload up to 5 SSH keys per account. This is useful if you connect from multiple computers. Manage your keys in Account Settings → SSH Keys.
When generating an API key, you can choose from:
ScopeAccess Level
read_onlyRead-only access to all endpoints
read_writeFull read and write access
billing_onlyOnly billing-related endpoints
Manage your API keys in Account Settings → API Keys. See the API Reference for details.
Yes. Nova Cloud uses:
  • SSH key authentication (recommended) or strong password requirements
  • Two-factor authentication (optional but recommended)
  • Firewall with all ports closed by default
  • Cloudflare-secured WebUI portal
  • Encrypted payment processing via Stripe
Your instance data is stored on the physical server and is only accessible via your authentication credentials.
When you destroy an instance, all data on it is permanently deleted. This includes any files, installed software, model weights, and outputs. Make sure to download anything important before destroying an instance.
