OpenComputer alternatives

Answer in brief

The 5 alternatives below are grouped by kind of sandbox, and each says what it does differently from OpenComputer. Start from whatever made you look: missing GPUs, session limits, self-hosting, pricing or isolation.

By the Agent Sandboxes editors · Updated

Why teams look beyond OpenComputer

Choose it when agents need a machine that persists and wakes, and you are comfortable with pool-based pricing and an evolving agent-first API.

  • The website does not name the hypervisor; QEMU/KVM appears only in the self-hosting guide.
  • No hibernate/wake timing, GPU or compliance information is published.
  • Pricing is by monthly machine pool, so short bursty workloads pay for idle capacity.
  • The product is framed around its own agent harness; using the VMs with another harness is less documented.

OpenComputer alternatives, by kind

Hosted sandbox platforms

SDK-driven sandboxes you create, run code in and destroy through an API.

  • Daytona

    Stateful sandboxes for AI-generated code — Linux containers, Linux and Windows VMs, macOS and GPU sandboxes — with snapshots, volumes and preview URLs.

    • Containers or VMs
    • BYOC
    • GPU
    • Pause/resume

    How it differs: Long-lived, stateful agent workspaces that need many SDK languages, GPUs, or Windows and macOS sandboxes. The strongest choice for stateful coding-agent workspaces and breadth of sandbox types; note the shift away from open source.

  • Superserve

    Persistent Firecracker microVM sandboxes for long-running agents, with pause/resume, memory-and-disk snapshots, forks and a credentials broker that keeps secrets out of the sandbox.

    • Firecracker microVM
    • BYOC
    • Pause/resume

    How it differs: Long-running coding and personal agents that need a persistent VM with pause, forks and brokered credentials. A well-documented persistent-VM sandbox whose credentials broker suits agents that must call third-party APIs safely.

Persistent VMs and agent computers

Full, long-lived virtual machines that an agent keeps, forks and returns to.

  • exe.dev

    Persistent root VMs for people and their agents, driven entirely over SSH (or the same commands via HTTPS and MCP), with replicated NVMe storage, VM copies and flat-rate CPU/RAM pools in nine regions.

    • VM (VMM per VM)
    • BYOC
    • Snapshots

    How it differs: Developers who want a fleet of persistent root VMs they and their agents reach over SSH, at a flat monthly price. A flat-rate fleet of persistent SSH-driven VMs for agent-assisted developers, rather than an SDK-driven sandbox API for high-volume automation.

  • Fly.io Sprites

    Persistent, hardware-isolated Linux computers for AI agents with a durable 100 GB disk, checkpoints, and no compute charges while idle.

    • MicroVM
    • Pause/resume

    How it differs: Long-running, stateful agent computers that should cost nothing while idle. The most natural “persistent computer per agent” model, with idle-free billing.

  • Islo

    Persistent microVM "Machines" for autonomous coding agents from the Incredibuild team, with a credentials gateway, snapshots and lifecycle policies, billed per vCPU-hour.

    • MicroVM (hypervisor not named)
    • BYOC
    • Pause/resume

    How it differs: Engineering teams running autonomous coding agents on full repositories with brokered access to GitHub, Slack and Linear. A credible agent-computer platform from an established build-tooling vendor, best suited to teams who want workflow orchestration and credential brokering alongside the sandbox.
