boxd is a cloud platform that provides persistent, hardware-isolated Linux VMs for development, with sub-10ms spin-up and sub-second live memory forking of running machines. Engineers can fork a machine mid-run—including processes, databases, and disk—to parallelize work across branches or agents, and restore from snapshots or checkpoints at any time. The platform is built from the hypervisor up, offering SSH access, MCP server integrations for coding agents, and self-hosting on any KVM host.

Problem
Traditional development environments are tied to a developer's local machine, which limits parallelization, prevents agents from running when the laptop is closed, and makes sharing work nearly impossible. Remote environments are often slow, expensive, and treated as scarce resources, creating a bottleneck as coding agents and multi-branch workflows become more common.
Solution
boxd provides a cloud platform for remote development where every developer gets fast, persistent, hardware-isolated Linux VMs on demand. The platform is built from the ground up—from the hypervisor to the kernel—to deliver sub-10ms environment spin-up and sub-second live memory forking of running machines, including processes, databases, and disk state. Developers can fork a machine mid-run to experiment in parallel, save snapshots to restore later, or roll back to checkpoints in place. SSH access works from any IDE or terminal, and MCP server integrations install directly into coding agents like Claude Code, Codex, or opencode. The entire stack can be self-hosted on any KVM host, giving organizations control over their infrastructure.
Target Audience
Primary users are software engineers and engineering teams at fast-growing companies who need fast, forkable, and shareable development environments for parallel work and agent-driven coding workflows.
Features
- Persistent Linux VMs with 2 vCPU, 8 GB RAM, and 100 GB disk by default, created via a simple CLI command
- Live memory forking of a running machine in under 200ms, including running processes, databases, and all disk state
- Snapshots that freeze a machine and allow restoration to a previous state, down to running processes
- Checkpoints that roll a machine back in place, restoring memory and disk without creating a new instance
- Hardware-level isolation for every environment, built on a custom microVM engine and Linux kernels
- MCP server integration that installs into Claude Code, Codex, or opencode, with GitHub, Linear, and Slack connections available org-wide
- Self-hostable on any KVM host, with a Raft-based control plane for scheduling and coordinating VMs across the fleet
