Agentic Index
N8n vs Sim (2026)
Both are open source and self hostable with strong visual builders, at 11.5 and 12.5 of 14. n8n is workflow automation with native AI nodes and language model integrated workflow building, from twenty euros a month annually with free self hosting, and an enormous integration library built over years.
Sim is agent first, with visual, conversational and code paths to the same workflow, at 25 dollars a month. n8n is the better general automation tool with agents added; Sim is agent native, and the integration library is n8n's real moat.
Choose N8n if
- Your workflows are mostly automation with AI steps rather than agents with tool access.
- The integration library is the moat and you need breadth immediately.
- Free self hosting with a large community is the position you want.
Choose Sim if
- Documented coverage is broader and agent native design matters for what you are building.
- Conversational building through Mothership is a genuinely different entry point.
- Managing deployed agents is part of the job, not just building workflows.
