InstaVM alternatives

Answer in brief

The 6 alternatives below are grouped by kind of sandbox, and each says what it does differently from InstaVM. 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 InstaVM

A broad, fast microVM platform for agent builders; confirm regions and session limits with the vendor before committing production workloads.

  • Free plan egress is restricted to known package managers and AI APIs.
  • Regions, GPU support and maximum session length are not documented.
  • SOC 2 Type II is listed only as an Enterprise feature with no report details.
  • A card must be on file even for the free tier.

InstaVM alternatives, by kind

Hosted sandbox platforms

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

  • E2B

    Open-source cloud sandboxes for AI agents, each a Firecracker microVM, with pause/resume, snapshots and forking.

    • Firecracker microVM
    • Open source
    • Self-hostable
    • BYOC
    • Pause/resume

    How it differs: Code interpreters and short-to-medium-lived agent tasks that need microVM isolation, with an open-source self-host path. The safe default for most agent builders: mature, open source, microVM-isolated and widely supported.

  • Leap0

    Firecracker microVM sandboxes in public preview, free during preview, with memory snapshots, forks, a per-sandbox firewall with credential-injecting header transforms and an XFCE desktop.

    • Firecracker microVM
    • BYOC
    • Pause/resume

    How it differs: Trying a full-featured microVM sandbox (desktop, LSP, git, snapshots) at no cost while it is in public preview. Feature-rich and free for now, but a preview service to trial rather than to build production dependencies on until billing and stability are settled.

  • Runtime

    Firecracker microVM sandboxes billed on active CPU at $0.025 per vCPU-hour, with pause that keeps memory, forks, SDKs in five languages and no plan fee.

    • Firecracker microVM
    • Pause/resume

    How it differs: Cost-sensitive agent workloads with many short runs, where active-CPU billing and a free monthly allowance matter. Aggressively priced and feature-dense, but single-region and unaudited; well suited to cost-driven batch agent work rather than regulated deployments.

  • 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.

Browser and desktop sandboxes

Hosted browsers and full desktops that computer-use agents click, type and browse in.

  • Cua

    Open-source computer-use infrastructure: Linux sandboxes as gVisor containers and macOS or Windows sandboxes as VMs, run locally, in your own cloud account or as shared "Spaces".

    • gVisor container or VM
    • Open source
    • Self-hostable
    • Pause/resume

    How it differs: Teams that want open-source computer-use sandboxes on their own Macs, servers or cloud accounts, including macOS VMs on Apple silicon. The broadest open-source option for computer-use sandboxes across macOS, Linux and Windows, now firmly a self-run toolkit after the hosted cloud shut down.

  • Scrapybara

    Hosted Ubuntu, browser and Windows desktop instances for computer-use agents, driven through Python and TypeScript SDKs with pause and resume.

    • Not documented
    • Pause/resume

    How it differs: Computer-use agents that need a ready-made Ubuntu or Windows desktop with a browser, bash, filesystem and Jupyter tools in one API. A compact computer-use desktop API with good tooling, but undocumented isolation and pricing and a parent company that has pivoted make it one to evaluate carefully.
