n8n is the breakout. The deployment is the wall.
n8n is the breakout workflow automation tool of 2026. Open source, self-hostable, AI-native, fairly priced. Most teams stand it up and hit production reality: auth, scale, governance, integration with non-n8n systems, AI nodes that need real model engineering, eval discipline.
From there it's one of two paths. Limp along on a deployment that works for the obvious workflows and breaks at the edge. Or migrate off, citing "scale issues" that were really integration and operations issues.
The tool isn't the problem. The deployment is. Production n8n needs the same operational substrate as any other piece of business-critical software. Eval suites, audit logs, RBAC, error budgets, observability.
