# Virtual Machines features and limits

> Full feature list for Virtual Machines on the Raff Platform, plus account, VM, and platform limits

<sub>Updated May 8, 2026</sub>

## Features

### Compute

* **Flexible sizing** — General Purpose and CPU-Optimized plan families across CPU, RAM, and base disk
* **On-demand resize** — change CPU and RAM by switching plans (VM must be stopped); the difference settles to your account balance
* **Disk resize (one-way)** — grow the OS disk without rebuilding (VM must be stopped)
* **No CPU throttling** — Raff never throttles your VM; sustain 100% CPU as long as your usage is legitimate
* **Custom images** — save a VM's OS disk as a reusable image and create new VMs from it

### OS templates

* **Linux** — Ubuntu, Debian, Fedora, CentOS, AlmaLinux, Rocky Linux, Alpine Linux, openSUSE
* **BSD** — FreeBSD
* **Windows** — Windows Server Standard (2019, 2022, 2025) and Datacenter (2022, 2025)
* **Marketplace** — pre-built application images
* **Custom** — any image you've saved from one of your VMs

### Networking

* **Public IPv4** — every VM gets a public IPv4 address by default
* **IPv6 support** — optional dual-stack networking
* **Optional VPC membership** — opt in by picking a VPC at create time, or join one later. A VM doesn't need a VPC to be useful
* **Shared VPCs** — multiple VMs in the same region can share one VPC for private peer-to-peer traffic
* **Reserved Public IPs** — keep a stable public address across VM rebuilds (separate product)
* **Unlimited bandwidth** — outbound traffic is unmetered and included on every plan; no per-GB egress charge

### Storage

* **Base disk** — SSD, included with the plan
* **Block storage volumes** — attach additional storage that can outlive the VM
* **Snapshots** — point-in-time copies of an OS disk or volume; per-GB-hour pricing
* **Backups** — automated Daily or Weekly schedules with configurable retention; storage draws from the shared free pool (see Pricing)
* **Multiple backup schedules per VM** — run Daily and Weekly side by side

### Security and access

* **SSH key authentication** — upload keys at creation, reuse on reinstall
* **Password authentication** — alternative; emailed to the account address on reset
* **Security groups** — stateful firewall rule sets attached to VM network interfaces
* **Reset password** — generate a new password and have it emailed to your account
* **Browser SSH terminal** — in-app SSH for Linux VMs without a local client
* **VNC console fallback** — graphical console for Windows VMs and recovery scenarios
* **Direct SSH and RDP** — connect from any client (`ssh`, PuTTY, Windows App, FreeRDP, Remmina, …)

### Lifecycle and recovery

* **Reinstall (Change OS)** — switch to a new OS template; preserves IP and attached volumes, deletes snapshots and backups
* **Factory reset** — fresh OS install on the same template; preserves snapshots, backups, and volumes
* **Hard reboot** — force-restart for unresponsive VMs
* **Bulk operations** — select multiple VMs in the list and stop or delete them in one action
* **Custom images for backup-based recovery** — Raff support can build a new VM from any retained backup if the original is destroyed

### Organization

* **Tags** — free-form labels with optional priority (1-9), account-wide
* **Group by Tag** — list view grouped by tag, ordered by priority then name (up to 2 levels of sub-grouping)
* **My Notes / Team Notes** — per-VM private and team-visible notes
* **Hostnames** — per-VM display name editable any time

### Observability

* **Performance graphs** — CPU, Memory (Used / Free), Network Traffic (RX / TX per interface), Disk Throughput, Total Outbound Data Transfer
* **Time ranges** — 30m / 1h / 2h / 6h / 24h / 7d / 1m / All
* **VM Information side panel** — live summary of pricing, status, credentials, resources, network, storage, and backup/snapshot counts

### Billing

* **Subscription by default** — pay in advance from your account balance for the term (Monthly / Yearly / 2-Year)
* **Term discounts** — Yearly and 2-Year save 17% vs Monthly
* **Credit on delete or downsize** — unused days and hours go back to your account balance (not your card)
* **Pay-as-you-go on request** — available for enterprise and SMB customers
* **Stopped VMs are billed** — `passive` VMs retain reservations and continue under their subscription term
* **14-day money-back guarantee** — on subscription purchases via the dashboard checkout
* **Multiple payment methods** — Google Pay, Visa, Mastercard, American Express, Diners Club; cards are saved for future renewals
* **Account balance applied first** — checkout deducts from your balance before charging the card
