I've been working on an open-source platform to build agentic workflows. I really wanted a Figma-like experience for building agents.

This seems really interesting. I tried running a swarm on my landing page but didn't get a completed email. I'll try it again, though!

hi! Looking at your swarm results, you might not have given the swarm login credentials to use, which is why most of the runs are failing out. Please feel free to try it again and give them access.

Try out https://hn.simstudio.ai for a live example, but we're also releasing templates this week to see community workflows.

I think OP is more referring to examples on how to set a workflow, like what would the equivalent "Hello World" / "FizzBuzz" / "Send an alert notification to [location] if [condition]". We're still trying to identify when and where using an agent is beneficial, so some use cases that I can review and fiddle with to match my workflow will help.

Really cool platform, so I'm interested in using it!

adding some examples and templates this week, and in our discord we are gonna maintain a showcase where ppl can post the cool workflows they've built.

That's awesome! I like the visual rendering on the canvas.

Thanks! I will definitely try out Sim Studio later today. It looks great, nice work!

We believe a visual solution is the best way for developers — and LLMs — to build applications in the future.

Thanks for the suggestion! We're adding in a prompt to workflow this week.

The big names out there are n8n and flowwise. I'd encourage you to try them out and let us know what you think compared to Sim Studio! We have a logs page that shows execution duration, tool call duration, tokens used, the cost based on the model you selected, etc.

Thanks. It would be nice to find your expert comparison of Sim Studio to these other tools in your docs. The comparisons you already made in this thread is a great resource too ofc.

Exactly

Thank you! Yes - we are adding variable resolution to the for each input. Let us know if there's anything else you'd like to see!

Thank you! n8n has done really well over the last few years to simplify the workflow building process. I responded to this in a previous comment, but we believe the agent building process should be more open, meaning fewer abstractions between the interface and the model provider. We want our platform to be as lightweight as possible.

How this translates in the application is through features like allowing for custom tool calling with code execution, JSON schema input for response format, etc. I'd love to hear your thoughts using Sim Studio - let us know how we compare to the other workflow builders!
