Who offers it

Part of Built-in agents, which explains why it matters.

Fully: Agent 37, Boat, boxd, InstaBox, Lizard, Sandboxer and Vercel Sandbox. With a catch: Daytona and E2B. Not at all: Blaxel, Cloudflare Sandbox, Modal, Morph, Runtime, Sprites and Tensorlake.

  • Agent 37Yes6 templates

    Hermes, OpenClaw, Claude Code, Codex, Grok and OpenCode, plus Pi and n8n.

    docs-confirmed “`agent37-hermes` | Hermes, the general agent: chat, browsing, code, files.” Source

  • BoatYes7 harnesses

    Claude Code, Codex, Pi, OpenCode, Prime Agent, Kimi Code and Mistral Vibe.

    docs-confirmed “Every sandbox has seven coding-agent harnesses, installed and ready” Source

  • boxdYes3 agents

    Claude Code, Codex and OpenCode, with an in-VM CLI already signed in.

    docs-confirmed “Every boxd machine ships with three coding agents” Source

  • InstaBoxYes

    Both are in the default and agent templates; sign-ins persist because home is on the data disk.

    docs-confirmed “Claude Code, Codex” Source

  • LizardYes5 agents

    Codex, Claude, OpenCode, Pi and Prime templates, plus a base image.

    docs-confirmed “`base`, `interpreter`, `codex`, `claude`, `opencode`, `pi`, `prime`, `desktop` and `desktop-camoufox`” Source

  • SandboxerYes6 harnesses

    Claude Code, Codex, OpenCode, Pi, Kimi Code and Mistral Vibe.

    docs-confirmed “installed in every sandbox.” Source

  • Vercel SandboxYes

    The default universal image includes coding agents, but you drive them yourself.

    docs-confirmed “which includes the current Node.js LTS, Python 3.14, coding agents, and common utilities.” Source

  • DaytonaWith a catch

    The catch: OpenClaw is in the default snapshot, but Claude Code and Codex are not; those need an install step.

    docs-confirmed “OpenClaw comes preinstalled in the default Daytona snapshot, so the command above is all you need.” Source

  • E2BWith a catch

    The catch: A prebuilt Hermes template exists, but the default image has no agent and there is no Claude Code or Codex template.

    docs-confirmed “E2B provides a pre-built `hermes` template with the Hermes CLI and bundled skills already installed.” Source

  • BlaxelNo

    Note: The default image is a bare sandbox; agents are code you deploy or an MCP server you connect.

    Agents Hosting is a separate product for your own Python or TypeScript agent.

    inferred “Sandboxes are instant-launching virtual machines” Source

  • Cloudflare SandboxNo

    Note: The current base images ship no coding agent; you add one in your own Dockerfile, as the guides do.

    docs-confirmed “include none of them.” Source

  • MorphNo

    Note: Devboxes boot from templates you build; no agent is in the default image.

    Agents are driven through the tmux API after you install them.

    inferred “Devboxes expose a full tmux API” Source

  • RuntimeNo

    Note: The default image ships languages and tools but no coding agent; you install the agent yourself.

    docs-confirmed “No bridge harness (Claude Code, Codex) has run on Runtime yet.” Source

  • SpritesNo

    Note: Sprites provide plugins and integrations for agents, but no agent is in the image.

    inferred “Official plugins for every serious coding agent, plus SDKs and native integrations.” Source

  • TensorlakeNo

    Note: The managed images ship an OS, a desktop and tooling; no coding agent is installed.

    You add an agent through a custom image or the OpenCode plugin.

    inferred “The managed tensorlake/* images, what ships in them” Source
