Arcbox
Agent Computer platform: isolated VMs for agents on Linux, Windows, macOS, iOS, and Android
ArcBox delivers what it promises: real hypervisor isolation for agents, with sub-50ms sandbox creation and snapshot restore around 22ms. The open-source runtime is a strong trust signal, but Linux/Windows are still waitlist-gated and macOS/iOS/Android are sales-only, so immediate self-serve access is limited. If you need production-grade, isolated agent environments today and don't mind a waitlist, it's worth serious consideration.

About Arcbox
ArcBox is an Agent Computer platform that gives each AI agent its own isolated virtual machine—a full operating system with its own kernel, filesystem, and network. Instead of sharing a container runtime and hoping permissions hold, every agent runs on a hypervisor boundary, so the isolation is real and the audit trail is clean. The platform offers three forms of the same environment: Computer (persistent, snapshot and resume), Sandbox (ephemeral, created in milliseconds), and Runner (fresh per CI job). This covers five operating systems: Linux (Ubuntu, Debian, any OCI image), Windows 11 and Server 2022, macOS, iOS, and Android. Linux and Windows are open in waves via waitlist; macOS, iOS, and Android are planned with you through sales because of Apple's licensing constraints. The underlying runtime, ArcBox Core, is open-sourced (MIT/Apache-2.0) on GitHub, so you can read and audit exactly what runs your agents. The CLI (abctl), Python, TypeScript, and a REST API expose the same four verbs—create, exec, snapshot, destroy—across every OS, and a lifecycle event stream replaces polling: you subscribe to ready, exited, snapshotted, destroyed events. ArcBox Desktop, a native SwiftUI app with a Rust runtime, is also available for macOS as an open-source Docker Desktop alternative. Buyers should note: this is usage-based pricing, billed by the second, with a Free tier that includes usage credits and up to five concurrent environments. For teams building agentic applications, running CI with VMs, or needing GPU-less, secure sandboxes that can be kept for months or thrown away in seconds, ArcBox is a credible, transparent choice. Compared to generic cloud VMs or container-based sandboxes, ArcBox's snapshot restore in ~22 ms and per-second metering on an open-source runtime offer both speed and control.
Behind the Verdict
ArcBox is not just another container tool; it's a pivot toward giving every agent a real computer. The architecture is refreshingly opinionated: each environment boots its own kernel, the boundary is the hypervisor, and you get an event stream instead of polling. That matters when you're running untrusted agents or need deterministic CI. When should you pick this? If you're building agentic applications that handle sensitive data or need long-lived state, the Computer form with snapshot and resume (restore in ~22 ms) is a killer feature. You can keep a machine for months, snapshot it, stop it (only storage is billed), and resume it nine days later with the same disk and IP. That's a workflow you don't get from containers. If you're running CI, the Runner form gives you a fresh VM per job, torn down after—no leftover state, no shared kernel. The event stream means your orchestration can react to ready/exited events without polling, which simplifies your code. When should you pass? If you need self-serve access right now, the waitlist is a real blocker. Linux and Windows are in waves, and macOS/iOS/Android require a sales conversation because of Apple's licensing. If you can't wait, you'll have to fall back to other providers. Compared to alternatives: OrbStack and Docker Desktop are for local containers on macOS; ArcBox Desktop is an open-source alternative, but the Agent Computer platform is a different animal—it's a cloud service with VMs. If you're comparing to AWS EC2 or GCP, ArcBox's per-second metering and snapshot speed are compelling, but you need to get past the waitlist. A caveat on the Free tier: it includes usage credits and up to five concurrent environments, but it's tied to Linux/Windows machines. If you need macOS, iOS, or Android, you'll be talking

Where the pricing makes sense
The company stage and team size where Arcbox's pricing actually pencils out — and where peers do it cheaper.
ArcBox's freemium model is ideal for individual developers and small teams on Apple Silicon who want zero cost now. Compared to Docker Desktop (which charges for larger businesses) and OrbStack (paid), ArcBox's free personal tier and free beta commercial tier offer a cost advantage, but lack enterprise features like SSO that those tools provide at higher tiers.
Setup time & first value
How long it actually takes to get something useful out of Arcbox — broken out by persona, not the marketing-page minute.
For a macOS developer using Homebrew, installation is a single command (brew install --cask arcbox) and containers run immediately; first value in under 5 minutes. AI sandbox setup via abctl is similarly quick, with sandbox creation in under 125ms. For complex custom stacks, expect 30-60 minutes to configure network and filesystem options.
Switching to or from Arcbox
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From Docker Desktop: Pull your existing docker-compose files, and ArcBox runs them unchanged; no migration beyond installing the tool.
- →From OrbStack: Similar OCI compatibility; simply replace OrbStack with ArcBox and your containers work as-is.
- →From colima or raw Docker CLI: ArcBox offers a drop-in replacement for the Docker CLI, so your scripts continue to work.
- ↗To Docker Desktop: Since ArcBox is OCI-compatible, your containers and images work in Docker Desktop without modification.
- ↗To OrbStack: Similarly, export your images or volumes as needed; OCI compatibility ensures transfer.
- ↗To plain Docker for Linux: Your containers are portable; just update scripts to use the Docker CLI directly.
