How does Sim actually compare to n8n or Langflow for someone who already has a few agent flows running? Curious what the real differentiator is beyond the open-source angle.
Sim
@gkeaksoyakhabw Sim's biggest differentiator is the ability to build across your entire workspace with chat. You're able to monitor and debug production workflows with Sim and have it alert you for any errors or anomalies in production agents.
Sim has agent skills, file storage, native tables and vector storage, and some more capabilities that are built natively alongside workflows.

Congratulations Team Sim,
That 90% chat-over-canvas shift is fascinating 😅 We're in the automation space too, so I'm curious, can you explain a bit how Sim decides when to use a deterministic step vs an actual LLM call? That "don't burn tokens on work that didn't need an LLM" idea sounds simple but feels hard to get right in practice.
Sim
@mittalpatel thank you! The two types of nodes in the workflow are either deterministic "function", "API" or LLM-based "agent", "router", "evaluator", etc. Users can choose between either!
I'd love to see more examples of workflows that have been built with Sim. What kind of use cases are you envisioning for the 1,000+ integrations?

@aymnart
I've seen everything from horse stables health tracking to home assistants to orchestrating thousands of manufacturing facilities. Honestly, you can do whatever you like.
How does the open source license work in practice here, is the core self hostable for free or is there a managed cloud version that kicks in once you need those 1000+ integrations?
Sim
@uzenaysenu87134 free forever. The only module not in the OS repo is the Sim agent, which you can get an API key for.

Congratulations on the launch!
the chat to agent workflow looks incredibly intuitive. how does Sim decide when to use deterministic steps versus an LLM during execution?
Sim
@avery_thompson2 it's entirely within your control to set up your workflow deterministically or LLM-based. If you'd like an agent to decide on the path, you can add a router that routes the workflow one way or another depending on the context you have at that point in time in the workflow.
congrats! building agents through natural language feels like the right direction. how much manual editing is typically needed after Sim generates an agent?
Sim
@imogen_wallace if you come in with a good prompt, most workflows and agents are one-shottable!
The token cost angle is underrated honestly 🚀
Everyone talks about agent capabilities but nobody talks about how expensive they get at scale. How much are teams typically saving once they switch to deterministic steps where possible?
Sim
@amna9 deterministic steps cut out the expensive tool call and processing steps that normally happen first when running an agent. Now, they only receive the context they need to produce a relevant output.
