# Sim

> Sim is a visual workflow builder for LLMs that lets you build and deploy AI agent workflows using a drag-and-drop canvas with 100+ model and app integrations.

Sim is an open-source, Figma-like visual canvas for building and deploying AI agent workflows. It connects to 100+ LLMs and apps, enabling both technical and non-technical users to compose complex multi-step agent pipelines without writing boilerplate code. Sim supports scheduling, looping, parallel execution, human-in-the-loop steps, and more — all from a single drag-and-drop interface. It is SOC2 compliant and offers a CLI/SDK for programmatic access.

- **Visual Workflow Canvas**: *Drag-and-drop blocks (Agent, Function, Router, Loop, Parallel, Condition, etc.) onto a canvas to compose agent pipelines visually.*
- **100+ Integrations**: *Connect immediately to services like OpenAI, Gemini, Groq, Ollama, Slack, GitHub, HubSpot, Salesforce, Notion, Jira, and many more.*
- **Flexible Execution Blocks**: *Use Starter, Webhook, Scheduler, Loop, Parallel, and Condition blocks to control workflow logic and timing.*
- **Human-in-the-Loop**: *Insert approval or review steps into any workflow to keep humans in control of critical decisions.*
- **Knowledge & Vector DB Support**: *Connect to Pinecone, Qdrant, and other vector databases for RAG-powered agent workflows.*
- **MCP Integration**: *Native support for Model Context Protocol (MCP) tools, enabling standardized model-tool communication.*
- **CLI/SDK Access**: *Use the Sim CLI or SDK to trigger, manage, and integrate workflows programmatically from your own codebase.*
