AI Agent Platforms Compared: CrewAI, Dify, n8n, and Clero
Most comparisons stop at features. This one compares how each platform gets work done: who delegates, who executes, and where the finished work lands. Clero's answer — a PM agent that delegates to specialist agents across docs, sheets, chat, and workflows. Runs on autopilot, with you in the cockpit.
| CrewAI | Dify | n8n | Clero | |
|---|---|---|---|---|
| What it is | Code-first framework for building agent crews (Python). | Visual LLM app builder (workflows + RAG apps). | Node-based workflow automation. | AI workspace where a PM agent delegates to specialist agents that execute real work. |
| How work gets done | You write Python to define agents and tasks; execution is code-driven. | You assemble app workflows visually. | You wire trigger→action nodes; automations run on schedules/events. | You describe the goal; the PM agent delegates, and specialist agents draft, update, send, follow up, verify, and publish — you approve at gates. |
| Where finished work lives | Your codebase/terminal output. | Inside the app UI. | Inside connected tools via nodes. | In your workspace — docs, sheets, chat, workflows — as artifacts you can edit. |
| Delegation & control | Manual code-level orchestration; no built-in approval UI. | Workflow steps, human review optional per node. | Human-in-the-loop nodes available, but no project-level PM. | PM agent delegates; approval gates keep you in the cockpit — nothing ships without your call. |
| Model flexibility | Bring your own keys via code. | Multiple providers supported. | Bring your own keys per node. | Use any model from any provider in one workspace — no vendor lock-in. |
| Pricing model (qualitative — verified against vendor pages 2026-08-03) | Open-source core + enterprise/cloud plans. | Free/cloud tiers, usage-based. | Free self-host + paid cloud tiers. | Flat subscription — Solo $15/mo, Pro $75/mo (5× limits), Max $150/mo (15× limits). No credit math on public pages. |
