🧱 easy, fast, local microVMs for untrusted workloads

Tool to build & run portable, lightweight, self-contained virtual machines.

NixOS MicroVMs

Fork() for AI agent microVMs. Spawn 100 children in ~100ms from a warm parent; BRANCH a live VM in ~150ms. KVM-isolated, snapshot CoW.

A multi-sandbox container runtime that provides cloud-native, all-scenario multiple sandbox container solutions.

Lock, Stock, and Two Smoking MicroVMs. Create and manage the lifecycle of MicroVMs backed by containerd.

Infrastructure that's powering E2B Cloud.

Dynamically provision Stateful Persistent Replicated Cluster-wide Fabric Volumes & Filesystems for Kubernetes that is provisioned from an optimized NVME SPDK backend data storage stack.

smolBSD is a tiny BSD UNIX (NetBSD) system creation tool, primarily aimed at building modern, lightweight, fast micro VMs

Firecracker-like microVMs for Proxmox VE — KVM isolation, under 200 ms boot.

The Cluster API provider for creating microvm (i.e. Firecracker, Cloud Hypervisor) clusters

My entire infrastructure and computing environment.

Run AI agents on real and isolated machines — own kernel, filesystem, and network — with <200ms boot. Local first, OCI compatible, pure Rust.

Lightweight MicroVM engine built on Cloud Hypervisor. Features include OCI and cloud image support, instant snapshot and clone via reflink, Windows 11 guest support, CNI networking with TC redirect, memory balloon, hugepages, and a Docker-like CLI. Designed for AI sandboxing, cloud desktops, and ephemeral dev environments.

An open taxonomy and scoring framework for evaluating AI agent sandboxes: 7 defense layers, 7 threat categories, 3 evaluation dimensions, 27 "sandboxes" scored.
