Introduction

ClawLess is an innovative, serverless, browser-based runtime designed for Claw AI Agents, powered by WebContainers. It enables the execution of AI agents entirely within the browser, eliminating the need for a backend server. This project provides a fully sandboxed Node.js environment, complete with a built-in editor, terminal, policy engine, and comprehensive audit logging. Built on the GitAgent Standard, ClawLess offers a secure and isolated environment for developing, testing, and running AI agents.

Installation

To get started with ClawLess, you can either clone the repository and run it locally or install it as a dependency in your project.

Run Locally

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

Install as a Dependency

npm install clawcontainer

Examples

ClawLess showcases the power of running AI agents directly in the browser through compelling examples. One demonstration involves an AI agent building a PowerPoint presentation using pptxgenjs. The agent installs the package, generates a multi-slide presentation with charts and images, and saves it to the virtual filesystem, all without a server. This highlights the ability to leverage over 3.4 million npm packages within the browser environment.

Another example features an AI agent constructing and previewing a calculator application. The agent's code generation, execution, and live preview occur entirely within the WebContainer sandbox, demonstrating full virtual filesystem access and an isolated WASM runtime. Every action, from process spawns to file writes and network requests, is meticulously tracked through a complete audit trail, ensuring transparency and control. Furthermore, a declarative YAML-based policy engine allows users to define precise guardrails, controlling agent behavior, file access, and resource limits on the fly.

Why Use It

ClawLess offers a unique and powerful solution for AI agent development and deployment. Its serverless, browser-based architecture significantly simplifies setup and reduces operational overhead. The WebContainer-powered sandboxed runtime provides unparalleled security and isolation, ensuring agents operate without access to the host system. Developers benefit from a rich environment featuring the Monaco Editor and xterm.js terminal, mirroring a full development setup. With comprehensive audit logging and a flexible policy engine, ClawLess provides the necessary tools for observability, compliance, and controlled agent execution, making it an ideal platform for secure and efficient AI agent development.
