Apple container alternatives
The 6 alternatives below are grouped by kind of sandbox, and each says what it does differently from Apple container. Start from whatever made you look: missing GPUs, session limits, self-hosting, pricing or isolation.
Why teams look beyond Apple container
The strongest isolation you can get for local containers on a Mac from the OS vendor itself, at the cost of maturity and platform reach.
- Apple silicon and macOS 26 only; Intel Macs, Linux and Windows hosts are not supported
- No snapshots, pause/resume or documented SDK beyond the CLI and an XPC API
- Memory freed inside a container's VM is not returned to macOS (ballooning only partially supported), so long-lived heavy containers may need restarts
- The project notes the initial release lacks many common containerisation features and that breaking changes may occur
Apple container alternatives, by kind
Open-source runtimes to self-host
Open-source sandbox runtimes you run on your own servers or Kubernetes.
BoxLite
Embeddable, daemonless microVM library that runs OCI images in hardware-isolated boxes on a laptop or server, with an optional managed cloud.
- microVM + jailer
- Open source
- Self-hostable
How it differs: Embedding a microVM sandbox directly in your own process on a laptop or server without running a daemon. A practical choice when you want microVM isolation embedded in your own process rather than behind a service.
Microsandbox
Open-source, local-first microVM runtime that gives each sandbox its own Linux kernel, with an optional managed cloud.
- MicroVM (libkrun)
- Open source
- Self-hostable
- BYOC
- Snapshots
How it differs: Self-hosted microVM isolation on developer machines or your own servers. The most approachable way to get microVM-grade isolation locally or self-hosted.
Isolation primitives and runtimes
The hypervisors, user-space kernels, OS sandboxes and WebAssembly runtimes that sandbox platforms build on.
libkrun
A dynamic library that lets any program launch a microVM in-process, on KVM in Linux or Hypervisor.framework on macOS; used by crun/Podman, krunkit and microsandbox.
- In-process microVM
- Open source
- Self-hostable
- GPU
How it differs: Embedding a microVM in your own tool on Linux or Apple Silicon without shipping a separate VMM. The microVM library to reach for when you want VM isolation inside your own tool, especially on macOS.
Local sandboxes for coding agents
Isolation for agents like Claude Code, Codex or Gemini CLI on your own laptop.
Anthropic Sandbox Runtime
Open-source CLI and library (`srt`) that restricts filesystem and network access for any local process at the OS level, without a container or VM.
- OS-level (Seatbelt / bubblewrap)
- Open source
- Self-hostable
How it differs: Lightweight local sandboxing of coding agents and CLI tools. Excellent lightweight guardrail for local agents; pair with a VM for untrusted multi-tenant code.
Docker Sandboxes
Docker’s `sbx` CLI for running AI coding agents in microVM sandboxes on your machine, with an experimental Docker-hosted cloud.
- MicroVM
- Self-hostable
- GPU
- Pause/resume
How it differs: Running coding agents unsupervised on a laptop with microVM isolation. The easiest way to give local coding agents a real microVM boundary.
Windows Sandbox
Disposable Windows desktop built into Windows Pro, Enterprise and Education, running on the Microsoft hypervisor with a separate kernel and wiped on close.
- Hyper-V lightweight VM
- GPU
How it differs: Running an untrusted Windows application or a Windows-targeting coding agent on a disposable copy of the host OS. A free, well-isolated throwaway Windows desktop for single-agent or manual use, not a platform for running agents at scale.
