GreenStack
Umbraco hosting that scales with you

Not at all! We've handled all the Docker complexity for you. You'll just need to use our pre-configured Dockerfile and GitHub Actions workflow, both are ready to go and documented in our knowledgebase.

Beyond that, you can build and develop your website exactly as you normally would, using your preferred tools and workflows. Your developers don't need any Docker experience; they can focus on what they do best: building great websites.

If you need any help getting set up, our support team is always here to guide you through it.

Pricing: Umbraco Cloud applies annual price rises. GreenStack pricing changes only when infrastructure costs require it, not on an automatic yearly schedule. Your costs are predictable for budgeting and procurement.

Specialism: Both Umbraco Cloud and GreenStack are run by Umbraco specialists. The difference is access - on GreenStack, Umbraco Certified Masters answer your tickets directly. No tiered triage.

Flexibility: Umbraco Cloud locks you into their deployment model and infrastructure choices. GreenStack supports any CI/CD provider, multiple Docker registries, and gives you control over your stack.

Sustainability: GreenStack runs on 100% renewable energy with carbon offsetting included. Umbraco Cloud doesn't publicly commit to renewable infrastructure.

Migration: Free with every paid plan. Our Certified Masters handle the technical detail.

Database Performance:

GreenStack gives you a dedicated Azure SQL database. Legacy hosting uses SQL Express shared with up to 200 other databases on the same server. The performance difference is significant.

Modern Infrastructure:

• GreenStack: Ubuntu Linux with Docker containerization

• Legacy: Windows Server with shared resources

Control Panel:

• GreenStack: UmbPanel (our proprietary panel, actively developed)

• Legacy: SolidCP (standard panel, maintenance mode)

Platform Development:

• GreenStack: Our actively developed platform with continuous improvements

• Legacy: Maintained for Umbraco v4-12 compatibility

For Umbraco 13+, GreenStack delivers better infrastructure and performance.

Legacy hosting is designed for older Umbraco versions (v4-12) that cannot run on containerized infrastructure.

GreenStack Core is less than our legacy UmbOne package with significantly better infrastructure.

GreenStack is built on Docker Swarm and Ubuntu Linux industry-standard technologies that power some of the world's largest websites.

Your developers don't need to know these technologies though. We've handled all the setup and configuration so you can focus on building great Umbraco sites.

GreenStack Core supports Umbraco 13 and above (13, 14, 15, 16, 17+).

GreenStack Pro and Scale support Umbraco 17 and above. This is because load-balanced backoffice support was introduced in Umbraco 17, which is essential for our multi-replica architecture.

Replicas are copies of your website running at the same time in different locations. Think of it like having multiple versions of your site ready to serve visitors, if one has a problem, the others keep working seamlessly.

With GreenStack Pro and above, your site runs on at least two replicas in physically separate datacentres. This means better performance and automatic protection, if one server goes down, your visitors are instantly directed to another without any downtime.

Need to handle more traffic? You can add extra replicas to spread the load and keep everything running smoothly.

Yes! GreenStack fully supports load balancing the Umbraco backoffice with Umbraco 17 and above.

This means your editors can work efficiently even when your site is under heavy load or experiencing high traffic. Multiple replicas handle both your public-facing site and the backoffice, ensuring a smooth editing experience regardless of what's happening on the front end.

Load-balanced backoffice is available on Pro packages and above.

Absolutely! Upgrading from Core to Pro is straightforward and gives you instant access to load balancing across multiple locations.

If you need even more capacity or redundancy, you can add additional replicas beyond the standard two for a small monthly fee per replica. This is perfect for high-traffic sites or when you need maximum uptime guarantees.

Get in touch with our support team and we'll help you find the right configuration for your requirements.

Yes! You can purchase dedicated nodes within our datacentre regions for ultimate performance and control.

Dedicated nodes give you guaranteed resources that aren't shared with other customers, making them ideal for high-traffic sites or applications with specific performance requirements. They work seamlessly with GreenStack's load balancing—you can even combine dedicated and shared nodes in your configuration.

Contact our support team to discuss dedicated node options and pricing for your specific needs.

Yes! Mounts are persistent storage volumes that keep your data safe even when containers are updated or restarted. Unlike container storage which resets, mounted folders preserve your files permanently.

Need extra mounts for media libraries, uploaded files, or application data? Contact our support team and we'll configure them for your environment.

Absolutely! If our standard packages don't quite fit your requirements, contact us to discuss GreenStack Scale, our fully customisable enterprise solution.

We can build a unique package tailored to your specific needs, whether that's dedicated nodes, additional replicas, custom resource allocations, or specialised configurations. Our team will work with you to design the perfect hosting environment for your application.

At launch, we offer Europe (Germany) for shared hosting packages.

Dedicated node options are available in:

• United Kingdom

• United States

• Singapore

• Finland

We're actively expanding our shared hosting regions, contact us if you need hosting in a specific location and we'll discuss the best options for your requirements.

Absolutely! Free SSL certificates are included as standard with all packages, powered by Cloudflare's trusted certificate authority.

Your site gets automatic HTTPS with no configuration needed, we handle everything for you, including automatic renewals so your certificates never expire.

Core is single-server, designed for development environments, smaller production sites, and teams getting started:

• 2GB Basic Azure SQL database

• 10 custom domains

Pro adds load-balancing across two physically separate datacentres, automatic failover, and a 99.9% uptime guarantee. Plus more resources:

• 2 replicas across multiple datacentres

• 30GB storage

• 5GB server memory

• 250GB S0 Azure SQL database

• 20 custom domains
