N8n is being compared to Zapier as a self-hosted workflow automation tool that offers built-in integrations. While users appreciate its cost-effectiveness, there are significant frustrations regarding user experience and the complexity of creating custom apps. The AI capabilities seem to be more promotional than functional, responding to investor expectations rather than delivering valuable features. Users suggest that improvements in custom app management and user permissions would enhance its enterprise viability. Despite these drawbacks, some users find n8n useful for prototyping and API integration, making it a worthwhile option for certain needs, especially in educational contexts where free tools are preferred.
