Head-to-head
n8n vs Retell AI.
Side-by-side on ratings, pricing, pros, cons, and the honest take on which to pick. Cross-category comparison: n8n is a workflow builder and Retell AI is a voice ai agent.
| n8n | Retell AI | |
|---|---|---|
| Rating | 4.5 / 5 | 4.0 / 5 |
| Category | Workflow builder | Voice AI Agent |
| Tech level | low code | low code |
| Open source | Yes | No |
| Pricing | Open-source self-hosted (free — you pay only your server costs and model API tokens). Cloud plans from $24/month for hobbyists; $50–$100/month for serious teams; enterprise pricing for SSO and audit log requirements. AI agent node usage adds model API costs on top. | Pay-per-minute usage: ~$0.07–0.10 per minute of voice conversation. Free tier with limited minutes. Volume discounts at enterprise scale. |
| Best for | Teams with at least one developer who need flexible, powerful workflow automation with AI agents built in. Strong for marketing ops, customer support automation, internal tool orchestration, and any workflow that touches multiple SaaS APIs. Self-hosted option is the right pick when data residency or compliance matters. | B2B teams deploying voice agents for outbound sales, customer support, or appointment booking. Strong for builders who want a managed voice infrastructure without owning the telephony stack. |
| Not for | Teams with zero technical resources — initial setup requires comfort with a server (self-hosted) or at minimum YAML-shaped thinking (cloud). Workflows that only need 2–3 steps and basic integrations — Zapier ships faster for simple cases. Pure agentic-loop tasks where no external systems are involved — a dedicated harness like OpenClaw or Paperclip is the better fit there. | Teams that need full control over the voice synthesis pipeline (use ElevenLabs Conversational AI). Teams with very low call volume — the per-minute pricing pays back at scale, not for occasional use. |
Our verdict on n8n
The best workflow automation platform for teams with at least one developer — beats every no-code tool for complex multi-step automations with AI agents. Self-hostable for full data control, 400+ integrations, mature AI agent layer. The trade-off is real: initial setup requires technical capacity, and the learning curve is steeper than Zapier or Lindy. For technical operators in 2026, n8n is the default.
