Sim Studio, a YC-backed open-source platform for building AI agent workflows, just exploded onto GitHub’s trending list at #1 with 1,463 stars in 24 hours. The tool offers a Figma-like canvas for designing AI agents without heavy coding – and 60,000+ developers are already using it. Moreover, with SOC2 and HIPAA compliance, 100+ app integrations, and deployment options ranging from REST APIs to Slack bots, Sim Studio is making AI agent development accessible to teams of all skill levels. Here’s why it’s trending and how to build your first agent workflow in 10 minutes.
What is Sim Studio?
Sim Studio is an open-source platform for building AI agent workflows visually. Instead of wrestling with code-heavy frameworks, you drag and drop blocks on a Figma-like canvas to connect LLMs, tools, and external services.
The platform supports 100+ integrations including Slack, Gmail, Notion, Supabase, and Pinecone. Build conversational agents, automation workflows, or multi-agent systems – then deploy as REST APIs, webhooks, scheduled jobs, or chat interfaces.
It’s SOC2 and HIPAA compliant, supports hosted models (OpenAI, Anthropic) and local models (Ollama, vLLM), and offers self-hosting under Apache 2.0. Furthermore, Fortune 500 companies use it alongside 60,000+ developers.
Quick Start: Build Your First Workflow in 10 Minutes
Installation (Pick One)
Option 1: Cloud (No Setup)
Visit sim.ai and start building immediately. No installation required.
Option 2: Local Docker (Recommended)
git clone https://github.com/simstudioai/sim.git
cd sim
docker compose -f docker-compose.prod.yml up -d
# Access at http://localhost:3000Option 3: NPM One-Liner

Step 1: Create Workflow
Click “New Workflow” in the dashboard. Every workflow starts with a Start block that receives user input.
Step 2: Add Agent Block
Drag an Agent block onto the canvas and connect it to the Start block. Select your model (GPT-4, Claude, or local Ollama). Configure the system prompt: “You are a research assistant that finds and summarizes information.”
Step 3: Add Tools
Add Exa Search or Perplexity tool blocks. Connect to your Agent block and grant permissions. The agent can now call these tools during execution.
Step 4: Deploy
Click “Deploy” and choose: API (REST endpoint), Webhook (trigger on Slack messages), Scheduled (cron), or Chat (standalone interface).
You’ve just built and deployed an AI research agent in under 10 minutes.
Why Developers Are Choosing Sim Studio
Visual First, Code When Needed
The Figma-like interface lowers the barrier to entry. Non-technical stakeholders can understand and edit workflows, while developers can add custom function blocks for data processing when needed. Consequently, this hybrid approach beats pure code frameworks for rapid prototyping and beats no-code chatbot builders for complexity.
Enterprise-Ready Features
SOC2 and HIPAA compliance are rare for open-source AI tools. Encrypted secrets, Better Auth, and self-hosting make it viable for regulated industries. Fortune 500 adoption proves it scales.
Local Model Support (No Vendor Lock-In)
Run workflows with local Ollama models like Llama 3.1:
docker compose -f docker-compose.ollama.yml --profile setup up -d
docker compose exec ollama ollama pull llama3.1:8bThis avoids cloud API costs and keeps data on-premises.
Real-Time Collaboration
Socket.io powers live updates for simultaneous editing. Additionally, the AI Copilot generates nodes and fixes errors using natural language.
Sim Studio vs LangGraph vs CrewAI
Use Sim Studio when:
- Rapid prototyping is priority
- Visual workflows help non-technical stakeholders contribute
- Enterprise compliance (SOC2, HIPAA) is required
- 100+ integrations add immediate value
- Mixed technical teams need shared canvas
Use LangGraph when:
- Complex, cyclical workflows need precise state management
- Production environments require deep customization
- Advanced conditional logic is essential
- Code-first approach preferred
Use CrewAI when:
- Role-based multi-agent systems fit your use case
- Quick prototyping with excellent documentation
- Well-defined, predictable task automation
- Team collaboration metaphor matches your workflow
The decision matrix is simple: Sim Studio for visual and rapid, LangGraph for code-heavy and complex, CrewAI for role-based and simple.
What You Can Build with AI Agent Workflows
AI Assistants: Conversational agents with web search, calendar, email automation. Deploy as Slack bots or chat interfaces.
Automation Workflows: Data entry, report generation, customer responses. Pull from Google Sheets, process with LLMs, publish anywhere.
Research Agents: Use Exa or Perplexity to extract and structure information about people, companies, or topics.
API Orchestrators: AI Router blocks determine intent, call APIs, return unified JSON.
Multi-Agent Systems: Multiple agents collaborate, delegate, and handle complex logic.
Why It’s Trending
The 1,463 GitHub stars in 24 hours signal a shift from code-first to visual-first AI agent development. Developers want the power of LangGraph without the boilerplate, the enterprise features without vendor lock-in, and the rapid iteration without sacrificing complexity.
Sim Studio’s YC backing, open-source license, and 60,000+ developer community prove this approach resonates. However, the platform’s real-time collaboration, local model support, and 100+ integrations make it production-ready today.
Getting Started
Visit the GitHub repository to star, fork, or contribute. Follow the getting started guide to build your first workflow. Try the cloud platform to experiment without installation.
Sim Studio is betting that visual workflows will dominate AI agent prototyping while code-first frameworks remain for production complexity. Based on today’s trending stats, they might be right.
