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; first 3 free per VM (rolling)
- 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 —
passiveVMs 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
