We're a web hosting company.

Let's be friends.

We built Stackable because we watched web developers struggle with hosting for years. We tried to help, but over time we realized that developers struggle because web hosting isn't built for the way developers actually work. We built Stackable to change all that.

Scalable Containers

Stackable containers are web servers. They're the building blocks of your site.

We wanted our containers to be reliable and powerful so we built each a high-performance CentOS 5.3 Apache web server built on Sun Microsystems™ hardware with Xeon processors.

Each server has RAID10 on-board while all customer content is served from Network Appliance™ SANs. All customer data is backed up daily to additional off-site Network Appliance clusters in secure data centers.

Stackable Containers are built on the award-winning Parallels Virtuozzo™ platform allowing you to grow or shrink the amount of memory allocated to your containers to meet fluctuating traffic demands. Combined with Stackable's billing model, this means that you can shape your bill to closely match your expected traffic hour by hour.

Because we bill based on the amount of memory your container uses, it's up to you to allocate it as you see fit. Host as many websites on a single container as you'd like, it's fine with us.

Stackable Load Balancing

Stackable was designed from the ground-up to support load balancing. While you can vertically scale a single Stackable container all the way to 16G of memory instantly, you can instead add more capacity by provisioning additional containers to help spread the load. It's the same price either way.

In the rare event that you have a problem with a container, your users will never know because the Stackable load balancers instantly detect the problem and route traffic to working containers.

Stackable Control and API

We got tired of using typical hosting web control panels, too. They never gave us the flexibility to do what we really wanted and they usually ended up just getting in the way. So we built our own. It allows you to control your websites, quickly provision containers, add new environments and see the health of all of your websites quickly. It works just how we think a control panel should.

We think it's pretty great, but we understand that different people have different needs. That's why we took everything in our control panel and we made it available via a JSON API. Every object in the control panel is expressed in the API and you can use that functionality as much or as little as you like - up to building your own Stackable control panel that works just how you like it. Now that's powerful.

Stackable Environments

Stackable Environments allow you to create multiple copies of your website so that you can safely develop and test new features while your regular visitors are blissfully unaware. When you're ready to push those changes into production, your changes go live immediately — even across dozens of containers all at once - without dropping a single user session. Make a mistake? Roll changes back just as quickly.

Each environment on every site can be accessed independently via a unique hostname that's automatically generated. Best of all, your production website stays on a single IP address the entire time, no matter which environment you have your users pointed toward. Remember the days of making changes in DNS and waiting for those changes to propagate across the Internet? Yeah, we hated that too.

Sensible Pricing

It doesn't make sense to pay for more than you use. With Stackable's per-day pricing model, you have the freedom to increase your capacity to handle loads of traffic one day and then dial things back when the crush of traffic eases up. Pricing for Stackable starts at just $35/mo for a 256MB container. Learn more about our pricing.

Stackable Data Center

SLC1 sits in a privately-owned, secure data-center in downtown Salt Lake City, Utah.

The data center features 22 Gbit/sec of capacity spread across four upstream providers.

Power is provided by an independent, 12,000 V feed from a new substation fed via a dedicated connection buried under mass-transit to reduce the risk of accidental breaches.

Backup power is supplied by 3 Mitsubishi 9800 AD UPS's and 2 500 KVa diesel generators.
