Sim Studio lets you connect LLMs to Slack, Supabase, Pinecone, and Gmail to create research agents, support bots, or file parsers. Collaborate by inviting your team to your visual canvas.
I’m Emir, co-founder of Sim Studio. We're proud to launch our open source platform for building AI agent workflows @hummus.
Building multi-agent systems today means writing tons of boilerplate code or using clunky visual tools. Sim Studio lets you use LLMs without the abstractions, making it easy to build agent workflows integrated with tools like Supabase, Pinecone, Gmail, and Slack.
From instant API or Chat deployments to built-in observability and debugging, Sim Studio gives you everything you need to iterate quickly and reliably ship production-ready workflows.
📦 Instant APIs
Deploy workflows instantly as APIs, schedule tasks, or trigger via webhooks.
🔌 Integrate Anything
Easily connect databases (Supabase, Pinecone), messaging platforms (Slack, Gmail, WhatsApp), social platforms (X, YouTube), file parsers (Mistral), and your favorite model providers.
🛠️ Custom Logic
Design workflows visually with full support for branching, loops, conditional execution, and custom functions.
🔍 Built-in Observability
Monitor execution, track costs down to the cent, and trace LLM calls directly within your workflow—no need for separate logging apps.
🐞 Debug & Simulate
Rapidly test, iterate, and optimize workflows with real-time debugging and simulation tools.
📖 Fully Open Source
Transparent, extensible, and developer-first. Apache 2.0 licensed.
🏃 Get Started
We’re excited to hear your feedback! Dive in today:
i've been waiting for this! so much simpler than n8n.
how do you see the competiton working out in the long run?
Really impressed by how Sim Studio strips away the boilerplate complexity in building AI agent workflows while keeping it fully open source!
Btw, we're seeing more cursor-like AI-powered developer tools reshaping productivity.
This is easily the easiest to use orchestration tool ever. So simple to use, deploy, and most importantly to test and debug. Such a no brainer.
This tool could streamline my workflow with AI agents. How do you envision it transforming the design process?
I'm most impressed by the amounts of integrations that Sim Studio has. What's the best way to suggest new integrations if I come across something interesting? Do you see Sim Studio plugging in with MCP marketplaces like smithery.io?
Sim Studio looks like a seriously powerful platform for rapidly prototyping and deploying AI agents by visually connecting LLMs to essential tools like Slack and databases – the collaboration feature is a huge bonus!

Who hunted Sim Studio?
Sim Studio was hunted by Garry Tan. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
