Raff vs Kamatera: Simple VM Pricing or Custom Cloud Server Calculator? (2026)

Introduction

Raff and Kamatera both serve developers, SMBs, startups, and infrastructure teams, but they offer very different buying experiences. Raff focuses on published VM tiers, included NVMe SSD storage, unmetered bandwidth, and a compact managed platform. Kamatera focuses on highly customizable cloud servers where buyers can tune CPU, RAM, storage, server type, traffic, operating system, and location.

Choose Raff when you want predictable pricing and an integrated platform spanning VMs, managed Kubernetes, managed databases, functions/serverless, Raff Apps, object storage, private networking, load balancers, and backups. Choose Kamatera when you need a precise custom server shape, a broader location menu, or optional managed cloud operations.

Kamatera pricing in this comparison was checked against its public pricing and cloud-server pages in April 2026. Its calculator is highly configurable, so the final price varies with CPU type, RAM, storage, operating system, traffic, backup, licensing, and data center selection.

Raff Overview

Raff Technologies is a US-focused cloud platform built around straightforward infrastructure and application deployment. Raff offers:

• General Purpose and CPU-Optimized VMs
• Linux and Windows VM options
• Managed Kubernetes
• Managed databases
• Functions/serverless
• Raff Apps
• S3-compatible object storage
• Block storage volumes
• Private cloud networking
• Load balancers
• Snapshots and automated backups
• Firewalls, DDoS protection, and web console access
• API, CLI, and Terraform support

Raff uses fixed VM tiers, making it easier to map common workloads to a published monthly price. This works well for websites, APIs, staging environments, production apps, internal tools, CI/CD runners, databases, Kubernetes workloads, and small SaaS infrastructure.

Kamatera Overview

Kamatera is a long-running cloud infrastructure provider known for customizable cloud servers. Instead of relying only on fixed VPS bundles, Kamatera lets buyers configure CPU, RAM, storage, traffic, operating system, server type, and data center more granularly.

Kamatera's main strengths include:

• Highly customizable cloud servers
• Broad data center selection
• Monthly and hourly billing options
• Linux and Windows support
• Multiple server types
• Optional managed services
• Optional backups
• Load balancers, firewalls, and private networking
• A 30-day trial offer up to the published limit

Kamatera is strongest for buyers who already know the exact infrastructure shape they need. Raff is strongest for teams that want fewer configuration decisions and clearer package economics.

Pricing Comparison

Raff uses published VM tiers that include CPU, RAM, NVMe SSD storage, and unmetered bandwidth. Kamatera uses a configurable calculator, so the final bill depends on the selected resource shape and add-ons.

Published Entry Examples

Raff also offers General Purpose VMs from $5.99/mo for 2 vCPU / 2 GB / 40 GB NVMe SSD and $9.99/mo for 2 vCPU HiMem / 4 GB / 80 GB NVMe SSD.

Raff is easier to compare because the tiers are fixed and include unmetered bandwidth. Kamatera is more flexible because the buyer can configure the server more precisely.

Feature Comparison

Compute and Performance

Raff separates its VM lineup into General Purpose and CPU-Optimized categories. General Purpose fits development, low-traffic sites, staging, and everyday workloads. CPU-Optimized fits production applications, databases, build runners, and workloads that need more predictable compute.

Kamatera exposes server types such as Availability, General Purpose, Dedicated, and Burstable through its calculator. This is more flexible for advanced buyers but introduces more choices during deployment.

The practical distinction is simple: Raff optimizes for decision simplicity; Kamatera optimizes for configuration freedom.

Bandwidth and Traffic Policy

Raff includes unmetered bandwidth on VM tiers at a 3 Gbps standard port speed. Normal VM traffic therefore does not create a per-GB egress line item.

Kamatera's published examples include traffic allowances such as 5 TB, and additional traffic may affect the final price. That model can work well for predictable workloads but requires the buyer to include traffic in the calculator.

Raff is easier to budget for APIs, downloads, media, backup replication, and applications with unpredictable outbound traffic. Kamatera is suitable when the traffic profile is known and the broader customization options are more important.

Storage and Backups

Raff includes NVMe SSD storage in its VM tiers and supports snapshots, automated backups, block storage volumes, and S3-compatible object storage.

Kamatera lets buyers configure storage capacity and backup options separately. That is useful for infrastructure teams that want granular control, while Raff's packaging is easier for small teams that want storage and data protection to be part of the default VM workflow.

Regions and Data Center Footprint

Kamatera has the broader data center menu across the United States, Canada, Europe, the Middle East, Asia-Pacific, and Australia. It is the stronger choice when the workload requires a specific non-US location or broader geographic placement.

Raff operates from Vint Hill, Virginia and is better suited to teams prioritizing US-East workloads, predictable pricing, unmetered bandwidth, and a compact managed platform.

Managed Services and Developer Experience

Raff now extends beyond VM hosting. Teams can use managed Kubernetes, managed databases, serverless functions, Raff Apps, object storage, load balancers, private networking, and data protection from the same platform.

Kamatera's advantage is operational flexibility. Buyers can create customized servers, choose among many locations and operating systems, and add managed cloud services when they want to offload infrastructure administration.

Choose Raff when you want a simpler integrated platform. Choose Kamatera when you want a highly configurable infrastructure environment or a more customized managed-service arrangement.

Who Should Choose Raff?

Choose Raff when you want:

• Simple published VM pricing
• Unmetered bandwidth
• NVMe SSD included in VM tiers
• Managed Kubernetes and managed databases
• Functions/serverless and Raff Apps
• Snapshots, backups, load balancers, and private networking
• A lower-friction cloud experience for small teams

Who Should Choose Kamatera?

Choose Kamatera when you want:

• Highly customized CPU, RAM, storage, and traffic combinations
• Broader global data center selection
• Multiple server types
• Optional managed cloud services
• A calculator-driven infrastructure model
• More granular operating-system and licensing choices

Migration: Kamatera to Raff

A standard migration path is:

1. Inventory the Kamatera VM, attached storage, firewall rules, operating system, and dependencies.
2. Create a Raff VM with equal or greater CPU, RAM, and storage.
3. Install required packages and application dependencies.
4. Transfer files with rsync, SCP, Git, or the deployment pipeline.
5. Export and restore databases with native tools.
6. Recreate environment variables, secrets, firewall rules, and private-network settings.
7. Test the workload on Raff before changing DNS.
8. Lower DNS TTL, complete the final data sync, and move traffic.
9. Keep the Kamatera server temporarily as a rollback path.
10. Decommission the old server after production validation.

Conclusion

Raff is the stronger choice when you want predictable VM economics, unmetered bandwidth, included NVMe storage, and an integrated platform spanning VMs, Kubernetes, databases, serverless, application deployment, storage, and networking.

Kamatera is the stronger choice when you need highly customized cloud server shapes, broader geographic selection, optional managed operations, and a calculator-driven infrastructure model.

Choose Raff for a simpler cloud platform. Choose Kamatera for maximum configuration freedom.
