clawless: Run Claw AI Agents in a Browser Sandbox

Overview

ClawLess is a browser-based runtime for Claw AI agents. It uses WebContainers to provide a sandboxed Node.js environment, so developers can launch agents, edit files, run commands, and preview results without setting up a server for the runtime.

Its policy engine and audit trail are aimed at teams that need to constrain and inspect agent actions as well as execute them. The project also offers an SDK and templates for embedding or bootstrapping agent environments.

Key Features

• Runs Node.js agent workloads in a browser through WebContainers.
• Provides a Monaco-based editor and xterm.js terminal for working with files and commands.
• Applies YAML policies to file access, processes, ports, and runtime limits.
• Records process, file, network, and Git events in an audit log, with sensitive headers masked.
• Intercepts browser fetch and Node.js http requests.
• Supports GitHub repository operations and lifecycle plugins.
• Includes Anthropic, OpenAI, and Google AI provider support.
• Exposes a ClawContainer SDK and template-based agent setup.

Use Cases

• Agent developers can prototype code-generating workflows in an isolated browser environment without operating a runtime backend.
• Teams evaluating agent behavior can review logged file, process, and network activity and apply policies to limit actions.
• Developers building browser-based agent tooling can use the SDK to embed a terminal, editor, and container lifecycle in their application.
• Users experimenting with Claw agents can install packages and preview generated applications within the browser sandbox.

Getting Started

git clone https://github.com/open-gitagent/clawless.git
cd clawless
npm install
npm run dev

See the README and documentation for SDK configuration and further details.

Alternatives

• sandbox-sdk: It runs untrusted code in isolated Linux containers managed by Cloudflare, rather than running agents in a browser-based Node.js environment.
• computer: It gives agents durable Cloudflare-backed workspaces with container or Worker execution, rather than browser-based execution with policy controls and audit logs.

Considerations

The project is marked quiet, with no commits in the last 90 days, and its contribution history is concentrated in one of two contributors. It has one release in the past year, but no reported issue closures or merged pull requests in the last 90 days. The repository also reports no CI setup or tests, so teams should verify the workflows they rely on themselves.

Running locally requires Node.js. The README describes a browser-based WebContainer runtime and provider API keys, but does not document server-side deployment as a current capability. The roadmap lists persistent filesystems, multi-agent orchestration, cloud deployment, and built-in debugging as future work. The repository uses the MIT license; review its terms for your intended use.
