# sim: Your Intuitive Interface for LLM Agent Workflows

Sim Studio provides a lightweight, user-friendly platform for building and deploying AI agent workflows. As a TypeScript-based MCP Client, it focuses on simplifying the process of connecting Large Language Models (LLMs) with your existing tools, offering a visual approach to agent orchestration.

## Building Agent Workflows Visually

The core of Sim Studio is its intuitive interface, designed for quickly assembling AI agent workflows. Instead of deep-diving into complex code, developers can leverage a visual builder to define how LLMs interact with different tools. This approach streamlines the development process, making it easier to experiment with agent designs and deploy them efficiently. The platform aims to abstract away much of the underlying complexity, allowing for rapid prototyping and iteration of agent behaviors.

## Self-Hosting and Local Development

For developers who prefer to maintain control over their environments, Sim Studio offers straightforward self-hosting options. While a cloud-hosted version is available for immediate use, local deployment is simplified through an NPM package. This allows for running Sim Studio directly on your machine, providing a consistent development experience and enabling custom configurations without relying on external services.

To get started with a local instance, the process is concise:

```bash
npx simstudio
```

This command initiates Sim Studio, making it accessible for local development and testing of your AI agent workflows.
