OpenHands Runtime alternatives

Answer in brief

The 6 alternatives below are grouped by kind of sandbox, and each says what it does differently from OpenHands Runtime. Start from whatever made you look: missing GPUs, session limits, self-hosting, pricing or isolation.

Why teams look beyond OpenHands Runtime

The right sandbox layer if you are already building on the OpenHands SDK; elsewhere a general container or microVM sandbox is simpler.

  • Container isolation only; no microVM option is documented
  • Persistence, limits and hosted pricing are not documented on the runtime pages
  • Tightly coupled to the OpenHands SDK rather than a general-purpose sandbox API

OpenHands Runtime 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.

  • 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.

Open-source runtimes to self-host

Open-source sandbox runtimes you run on your own servers or Kubernetes.

  • Kubernetes Agent Sandbox

    Open-source Kubernetes controller and CRDs for isolated, stateful sandbox pods for AI agents, with first-class support on GKE.

    • gVisor or Kata
    • Open source
    • Self-hostable
    • BYOC
    • GPU
    • Pause/resume

    How it differs: Platform teams that want to run agent sandboxes on their own Kubernetes or GKE clusters. The leading open, Kubernetes-native way to self-host agent sandboxes, especially on GKE.

  • LLM Sandbox

    Python library that runs model-generated code through one API on Docker, Podman or Kubernetes, with Bubblewrap/nsjail local backends and an MCP server.

    • Docker/Podman/K8s container
    • Open source
    • Self-hostable

    How it differs: Python applications that need to run model-generated code in whatever container runtime they already have. A convenient backend-agnostic wrapper for teams that already run containers and want a Python-first code-execution layer.

  • SWE-ReX

    Runtime interface from the SWE-agent team for running agent shell sessions locally or in Docker, Modal and AWS Fargate sandboxes, built for massively parallel runs.

    • Docker / Modal / Fargate
    • Open source
    • Self-hostable

    How it differs: Running many SWE-agent-style shell sessions in parallel across local, Docker, Modal or Fargate backends. A thin, backend-agnostic shell runtime that is most useful when the goal is parallel coding-agent evaluation rather than a hosted sandbox.

Local sandboxes for coding agents

Isolation for agents like Claude Code, Codex or Gemini CLI on your own laptop.

  • 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.
