Detailed Comparison
OpenStack is a cloud operating system that controls large pools of compute, storage, and networking resources throughout a datacenter, all managed through a dashboard that gives administrators control while empowering their users to provision resources through a web interface. | Virtuozzo leverages OpenVZ as its core of a virtualization solution offered by Virtuozzo company. Virtuozzo is optimized for hosters and offers hypervisor (VMs in addition to containers), distributed cloud storage, dedicated support, management tools, and easy installation. |
Compute;Storage;Networking;Dashboard;Shared Services | A container (CT) looks and behaves like a regular Linux system. It has standard startup scripts;
Software from vendors can run inside a container without OpenVZ-specific modifications or adjustment;
A user can change any configuration file and install additional software;
Containers are completely isolated from each other (file system, processes, Inter Process Communication (IPC), sysctl variables);
Processes belonging to a container are scheduled for execution on all available CPUs |

What are some alternatives to OpenStack, OpenVZ?
Docker
The Docker Platform is the industry-leading container platform for continuous, high-velocity innovation, enabling organizations to seamlessly build and share any application — from legacy to what comes next — and securely run them anywhere
Apache CloudStack
CloudStack is open source software designed to deploy and manage large networks of virtual machines, as a highly available, highly scalable Infrastructure as a Service (IaaS) cloud computing platform.
LXD
LXD isn't a rewrite of LXC, in fact it's building on top of LXC to provide a new, better user experience. Under the hood, LXD uses LXC through liblxc and its Go binding to create and manage the containers. It's basically an alternative to LXC's tools and distribution template system with the added features that come from being controllable over the network.
LXC
LXC is a userspace interface for the Linux kernel containment features. Through a powerful API and simple tools, it lets Linux users easily create and manage system or application containers.
rkt
Rocket is a cli for running App Containers. The goal of rocket is to be composable, secure, and fast.
VirtKick
Software as a service platform for hosting providers.
Vagrant Cloud
Vagrant Cloud pairs with Vagrant to enable access, insight and collaboration across teams, as well as to bring exposure to community contributions and development environments.
Renderjuice
Managed cloud render farm for Blender and automated rendering workflows.
Vessel for OpenClaw: Managed AI Agents on Private VMs
300,000+ OpenClaw instances are currently exposed on the public internet (Shodan: port 18789). Most self-hosted setups miss the tunnel, skip the required flags, share containers. When your agent processes untrusted input and holds access to your accounts, that gap matters. Vessel provides private, dedicated hosting for OpenClaw agents. Each agent runs on its own GCP e2-standard-2 VM, its own kernel, its own disk, no shared memory with other tenants. No public IP. No port 18789 exposure. All traffic routes through an encrypted Cloudflare Tunnel. Secrets are managed separately from the runtime. Provision from a web dashboard, connect to Slack, Discord, or WhatsApp, and destroy when done. Your agent's data stays on your VM, your own Vessel.
Studio 3T
It's the only MongoDB tool that provides three ways to explore data alongside powerful features like query autocompletion, polyglot code generation, a stage-by-stage aggregation query builder, import and export, SQL query support and more.
