box, from ASCII, is a per-agent virtual computer designed for agent factories that need real sandboxes instead of stubbed shells. Each box is a persistent Ubuntu Linux virtual machine with full SSH and SCP access, a dedicated IPv4, Docker running inside, and a 60 fps virtual desktop so an agent can see and click a real GUI. Machines fork from disk snapshots in seconds, so an agent can branch state, try a workflow, and throw it away without reprovisioning. Every box ships pre-configured with the tools an autonomous agent typically needs — Docker, VS Code, Chrome, Ghostty, GitHub CLI, Rust, Node.js, and Bun — so most agent scripts just work on first boot. A single CLI, installable with one curl command on macOS, Linux, and Windows, drives creation, forking, and destruction, making it usable both from an agent script and from a human developer's terminal.

Box is an affordable, powerful Linux virtual machine (VM) sandbox specifically designed for AI agents. It features a persistent Ubuntu environment equipped with SSH, Docker, a virtual desktop, and rapid snapshot forking, making it an ideal platform for development and experimentation in artificial intelligence.
Box is designed to provide a flexible and powerful environment for developing AI applications. With its persistent Ubuntu setup, users can enjoy a seamless experience that allows for continuous work without interruptions. Here’s a closer look at its features:
Affordable Pricing: Box is often touted as a budget-friendly solution for developers who need a reliable VM without the hefty price tag associated with many cloud services. Pricing can vary based on usage, but it remains accessible for individual developers and small teams.
Essential Tools: The inclusion of SSH (Secure Shell) allows for secure remote access to the VM, enabling developers to manage their environment from anywhere. Docker support means users can easily deploy applications in isolated containers, which is crucial for testing and development in AI projects.
Virtual Desktop: The virtual desktop feature provides a graphical interface, making it user-friendly for those who prefer not to work solely in command-line environments. This is particularly beneficial for graphical applications or when visualizing data.
Snapshot Forking: One of the standout features of Box is its fast snapshot forking capability. Users can create snapshots of their VM states quickly, enabling them to experiment with different configurations or code changes without the fear of losing their previous work. This is especially useful in AI development, where iterations are frequent.
Box operates by providing users with dedicated Ubuntu virtual machines (VMs) that function like real servers. Each box includes a unique IPv4 address, high-frame-rate virtual desktop, and supports Docker for containerized workflows, enabling seamless interaction with applications and efficient task management for autonomous agents.
Box is designed to facilitate the operation of autonomous agents by providing them with robust and flexible environments. Here’s a closer look at its features:
Persistent Virtual Machines: Unlike ephemeral containers, each box operates as a full Ubuntu VM, allowing agents to execute tasks that require a stable environment. This means that agents can perform complex operations without the risk of losing their context or state.
Dedicated IPv4 Address: Each machine is assigned its own public IPv4 address. This feature ensures that outbound traffic behaves like that of a real server, making it ideal for applications that require consistent networking and integration with network-scoped tools.
60fps Virtual Desktop: The high-framerate virtual desktop enables agents with vision capabilities to interact with GUI applications and web browsers seamlessly. This is particularly useful for tasks that involve browser automation or require visual feedback.
Disk-Level Snapshot Forking: Users can fork a VM from a snapshot almost instantaneously. This allows agents to quickly branch their execution paths and test different scenarios without incurring significant overhead. For example, if an agent is testing a new feature, it can fork the VM, make changes, and if needed, revert back to the original state.
Docker-in-Box: The ability to run Docker within the VM allows agents to build and run containerized workflows efficiently. This setup avoids the complexities associated with nested virtualization and enhances the overall productivity of the agents.
Agent Factories: Box allows users to spin up thousands of isolated Linux sandboxes, making it a perfect substrate for fleets of autonomous agents that can work concurrently on various tasks.
Coding Agent Environments: Developers can utilize Box to provide coding agents with real machines to clone repositories, run tests, and open browsers during their work, enhancing their efficiency and productivity.
Task Branching and Bug Reproduction: The platform’s snapshotting capability enables agents to try alternative strategies during risky operations and merge back successful outcomes. This is essential for debugging, as it allows users to reproduce bugs in identical environments on-demand.
Box features a persistent Linux VM per agent, dedicated IPv4 addresses, a 60fps virtual desktop, disk-level snapshot forking, and Docker-in-Box capabilities. These features enable seamless development, testing, and deployment of applications in a robust, real server-like environment.
Box is designed for developers and teams requiring a versatile and powerful environment for software development and deployment. Here's a deeper look at its key features:
Persistent Linux VM per Agent: Each Box instance runs on a persistent Ubuntu virtual machine. This means that every user can access their own unique environment with SSH and SCP capabilities, allowing for a true server experience rather than just a temporary container.
Dedicated IPv4 Address: With a dedicated public IPv4 address assigned to each virtual machine, users can interact with network-scoped tools and applications as though they were operating on a physical server. This feature is crucial for scenarios that require consistent IP addresses for API calls or web services.
60fps Virtual Desktop: Box provides a high-framerate virtual desktop experience, enabling vision-enabled agents to interact with graphical user interfaces (GUIs) seamlessly. This is particularly beneficial for testing applications that rely on visual components, such as web browsers and design tools.
Disk-Level Snapshot Forking: Users can create instant forks from snapshots of their virtual machines. This allows developers to branch off and explore different execution paths without the risk of losing previous work. If a path fails, it can be discarded effortlessly, saving both time and resources.
Docker-in-Box: The integration of Docker within the Box VM allows users to build and run containerized applications without needing to exit the virtual machine. This enhances workflow efficiency by allowing developers to manage and isolate dependencies directly within their environment.
By exploring these resources, users can maximize their experience with Box and fully leverage its powerful capabilities for development and testing.
box is designed for developers, researchers, and automation experts who need scalable and isolated environments. It supports tasks such as running autonomous agents, coding in real-time, browser automation, task branching for experiments, and reproducing software bugs with precision.
box is a versatile platform particularly suited for various tech professionals including software developers, AI researchers, and QA testers. Here are some key applications:
Agent Factories: box allows users to quickly spin up thousands of isolated Linux sandboxes. This capability is essential for those developing autonomous agents that need independent environments to operate without interference.
Coding Agent Environments: Developers can provide coding agents with real machines. This means agents can clone repositories, execute tests, and interact with browsers seamlessly. This functionality enhances productivity and the accuracy of development workflows.
Browser Automation with Vision: By running a full Chrome instance on a virtual desktop, box enables vision agents to drive real web user interfaces. This feature is crucial for testing web applications where visual feedback is necessary.
Task Branching: Before undertaking risky actions, users can snapshot a virtual machine. This allows them to fork the environment to experiment with alternative solutions, ensuring that they can merge back successful changes without losing previous work.
Reproducible Bug Repros: Developers often face challenges reproducing bugs. With box, users can fork a known-good snapshot to create an identical environment on demand, making it easier to troubleshoot and fix issues.
