CLI (Node.js)
Manual
Detailed Comparison
Rocket is a cli for running App Containers. The goal of rocket is to be composable, secure, and fast. | 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. |
Composable. All tools for downloading, installing, and running containers should be well integrated, but independent and composable.;Security. Isolation should be pluggable, and the crypto primitives for strong trust, image auditing and application identity should exist from day one.;Image distribution. Discovery of container images should be simple and facilitate a federated namespace, and distributed retrieval. This opens the possibility of alternative protocols, such as BitTorrent, and deployments to private environments without the requirement of a registry.;Open. The format and runtime should be well-specified and developed by a community. We want independent implementations of tools to be able to run the same container consistently. | 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 rkt, 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
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.
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.
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.
SmartOS
It combines the capabilities you get from a lightweight container OS, optimized to deliver containers, with the robust security, networking and storage capabilities you’ve come to expect and depend on from a hardware hypervisor.
Clear Containers
We set out to build Clear Containers by leveraging the isolation of virtual-machine technology along with the deployment benefits of containers. As part of this, we let go of the "generic PC hardware" notion traditionally associated with virtual machines; we're not going to pretend to be a standard PC that is compatible with just about any OS on the planet.
Flatpak
It is a next-generation technology for building and distributing desktop applications on Linux
Lima
It launches Linux virtual machines with automatic file sharing, port forwarding, and containerd. It can be considered as some sort of unofficial "macOS subsystem for Linux", or "containerd for Mac". It is expected to be used on macOS hosts, but can be used on Linux hosts as well. It may work on NetBSD and Windows hosts as well.
