Pick n8n Agents if cost is the main constraint or if auditability or self-hosting matters. Pick Sakana AI 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 Sakana AI for the workflows where its specific strengths matter.
n8n Agents starts at Free · OSS; Sakana AI starts at Subscription. n8n Agents is the cheaper entry option. For team deployments the TCO can differ — use the AI Agent Rank TCO calculator for your specific volume.
Sakana AI 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.
