Agentic Index
Sim vs Stackai (2026)
Both build and deploy agents on enterprise data with low friction, at 12.5 and 11.5 of 14.
Sim is open source with visual, conversational and code paths to the same workflow, 25 dollars a month for Pro with 5,000 credits. StackAI is no code for building and deploying workflows and agents on enterprise data, free to 500 runs a month then enterprise custom per seat. Sim documents more and is open; StackAI is the cleaner no code experience for a team that will never touch the code path anyway.
Choose Sim if
- Documented coverage is broader and open source is a requirement.
- A code path matters because some of your workflows will outgrow a visual builder.
- Flat monthly pricing with credits is predictable.
Choose Stackai if
- Nobody on the team will write code, so a code path is not a benefit.
- Enterprise data connectivity is the specific problem you are solving.
- A free tier of 500 runs is enough to prove the use case.
