I found a 100% open-source alternative to n8n! (it runs locally, powered by local LLMs) Sim is a drag-and-drop UI for creating powerful AI agent workflows: Key features: - Real-time workflow execution - Connects with your favorite tools - Works with local models via Ollama - Intuitive drag-and-drop interface using ReactFlow - Multiple deployment options (NPM, Docker, Dev Containers) Sim outshines n8n with: - An intuitive interface - State-of-the-art copilot for faster builds - AI-native workflows for intelligent agents I used it to build a job finder for top YC startups & connected it to Telegram in minutes. Tech stack: - Sim to build the workflow - Firecrawl for web search - Docker, Inc to locally host everything The video below provides a step-by-step guide along with all the setup instructions. You can also find all the details in Sim's GitHub repository, linked in the first comment. _____ Share this with your network if you found this insightful ♻️ Follow me (Akshay Pachaar) for more insights and tutorials on AI and Machine Learning!

This tool might change how you build AI agents 👇 It’s called Sim Studio Sim (YC X25) — think Figma for AI workflows. Instead of wiring everything in code, you just drag, drop, connect, and run. Why it’s worth checking out: Open Source (Apache-2.0) → free, forkable, self-hostable. Runs anywhere → npx simstudio, Docker Compose, or in the cloud at sim.ai. Flexible workflows → branching, loops, tool calls, even local models with Ollama. Debug smarter → simulate your agents 1x, 10x, 100x and see exactly how they behave. 🔗 GitHub: simstudioai/sim Open source tools like this make agent building accessible to everyone — not just hardcore engineers. I’m excited to see what people will build with it.
