Pick n8n Agents if your stack spans many tools and integration depth is the constraint.
Try n8n Agents →Pick OpenAI Swarm if you want the highest autonomy and the verification loop is in place.

Pick n8n Agents if your stack spans many tools and integration depth is the constraint. Pick OpenAI Swarm if you want the highest autonomy and the verification loop is in place. Most working teams running both can use n8n Agents for primary work and OpenAI Swarm for the workflows where its specific strengths matter.
Both n8n Agents and OpenAI Swarm start in the same pricing range (Free · OSS vs Free · OSS). Total cost of ownership depends on your team size and volume — see the TCO calculator for your specific math.
OpenAI Swarm is the more autonomous of the two (Autonomous vs Semi-autonomous). Higher autonomy ships throughput faster but requires verification loops in place — see our autonomous-vs-copilot framing for when each tier wins.
Adjacent agents in the same category with overlapping capabilities — worth a side-by-side glance before you commit.
