👋 Hey Product Hunt! I'm Emir, co-founder and CEO of Sim.

Today Sim is open to everyone, and I couldn't be more excited to share it ❤️

Sim started with a mess of our own making. Waleed (my best friend and co-founder) and I were prompting Claude to build sophisticated automations in n8n, storing data in Supabase, and standing up infra for our APIs and MCPs, and we realized the stack we'd assembled just to build agents that automated our own work was a complete mess. Not to mention our token spend... So we set out to build the one platform we wished we had.

The problem: building AI agents today means stitching together frameworks, one-off scripts, and brittle automations that break the moment anything changes. We wanted one place to build an agent, give it access to our data across 1,000+ integrations, build a brain for memory, deploy it, and actually manage it over time. So we built one.

Sim is the open-source AI workspace for agents. Here's what makes it different:

🗣️ Build by chatting — describe what you want and Sim builds the agent and workflow for you. Or design it visually on a canvas. Or drop into code. Whatever fits the job.

🔌 1,000+ integrations + every major LLM — Slack, Notion, HubSpot, Salesforce, Gmail, and more, connected out of the box. Your agent says "message me on Slack when a deal closes" and it just works.

🧠 One workspace, shared context — Workflows, Tables, Knowledge Bases, and Files all live together, so your agents share memory and data instead of living in disconnected tools.

💸 Cost-efficient by design — Sim swaps token-hungry tool calls for deterministic steps and real code wherever it counts, so you're not burning tokens (and money) on work that never needed an LLM in the first place.

🚀 Built for real work — Slack bots, compliance agents, data pipelines, research assistants. Not demos, actual production agents.

🔓 Open source (Apache 2.0), SOC2, and already trusted by 100,000+ builders.

Who it's for: teams who want to put AI agents to work (IT, ops, and technical teams who need governance and control), and individual builders who care about speed and open source.

We're shipping fast and want to build this with you. Tell us what's missing, what's broken, and what would make Sim 10x more useful for you.

I'll be here all day and will read and reply to every single comment 🙌

The "chat to build" vs canvas vs code approach is interesting, most tools force you to pick one. Which one do most of your users actually end up sticking with?

Originally, Sim users were only building on the canvas. Now, more than 90% of the platform's usage comes from the chat. Sims love prompting!

Congrats on the launch!

100k builders on an open source tool is genuinely impressive.

BTW, what's the split between solo devs and actual teams using this in production?

@abod_rehman

Thanks so much! Great question. Solo agent builders account for 70%+ of the users on the platform, while teams actually account for 90%+ of agent and workflow runs.

who do you think gets the most value out of Sim today, developers, technical teams, or can non-technical users get productive quickly as well?

@aymi_malik

Great question.

Technical teams building agents and solo devs looking for automations get the most value out of Sim today.

Non-technical users still get loads of value from the Sim chat.

@emirkarabeg The mess of stitching frameworks and watching token spend go wild is incredibly relatable. Sim solving this by bringing workflows, tables, and knowledge bases into one shared context is huge for real production work. Can we seamlessly toggle between the no-code canvas and dropping into raw code for specific nodes, or do we have to pick one style for the workflow?

@tehreem_fatima5 you can decide which option you'd like to work with and interchange for each node in your workflow.

@emirkarabeg Being able to interchange it node-by-node gives the perfect balance between speed and full control. Absolute game-changer for dev workflows. Thanks for clarifying.

love that files and tables live in the same workspace layout, context switching between three different DBs and vector tools completely breaks agent memory. amzing launch

@priya_kushwaha1 thanks so much! You can think of Sim as a 'brain' that houses and interacts with data across knowledge bases (vector DB), tables, files, and workflows.
