The integration landscape is evolving rapidly. AI-powered workflows are no longer futuristic concepts—they’re becoming essential tools for modern integration developers.

But with multiple platforms emerging, each with different strengths and trade-offs, how do you choose the right one for your integration needs?

This guide compares three distinct platforms – CrewAI, Langflow, and n8n,examining their actual capabilities, limitations, and enterprise readiness based on real-world deployments and documented concerns.

Understanding the Three Platforms

Before diving into comparisons, let’s establish what each platform brings to the table and their documented strengths and weaknesses.

n8n Visual Automation

What it is: n8n is a workflow automation platform with 400+ pre-built connectors. It recently added AI capabilities through integrations with OpenAI, Anthropic, and other AI providers. Self-hosted or cloud-based options available.

Primary approach: Visual, node-based workflow builder. AI is one of many integration capabilities.

Enterprise readiness: SOC 2 Type II compliant. Enterprise plan includes SSO, SAML, LDAP, and advanced RBAC.

Best for: Teams needing broad integration capabilities with AI as one component, willing to implement governance frameworks.

⚠️ n8n Governance Considerations

Documented limitations for enterprise use:

  • Community nodes security risk: Community nodes have full system access and can execute malicious actions. Organizations must disable community nodes (N8N_COMMUNITY_PACKAGES_ENABLED=false) or carefully vet each node.
  • Limited RBAC granularity: Fine-grained per-workflow access control is not as mature as legacy enterprise automation tools. Large organizations need custom extensions or proxy-level policies.
  • Basic audit logging: While audit logs exist in enterprise edition, native SIEM integrations (Splunk, Elastic) require custom configuration.
  • Workflow versioning challenges: JSON-based workflows make proper Git version control awkward compared to code-first platforms.
  • Production scaling complexity: Horizontal scaling requires DevOps engineering and custom orchestration.

Mitigation strategies: Disable community nodes, implement external audit logging, plan RBAC extensions, use Infrastructure as Code for workflow versioning.
