Head-to-head
n8n vs Stack AI.
Side-by-side on ratings, pricing, pros, cons, and the honest take on which to pick. Both are in our workflow builder category — direct competitors.
| n8n | Stack AI | |
|---|---|---|
| Rating | 4.5 / 5 | 3.5 / 5 |
| Category | Workflow builder | AI application builder |
| 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. | Freemium. Team plans from $199/month. |
| 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. | Ops teams who want AI agents over their internal documents — SOPs, contracts, product specs, Notion wikis. |
| 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. | External-facing automations or multi-step process workflows — n8n handles those better for most teams. |
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.

Best for internal knowledge base and document Q&A agents. Handles SOPs, contracts, and Notion wikis well. Strong in its lane, expensive outside it.
Full Stack AI review →n8n
What works
- 400+ integrations — connects to virtually everything
- Self-hostable for full data control (free, you pay only server + model costs)
- Strong native AI agent support with model-agnostic node design
- Large, active open-source community — fair-code licence
- Meaningfully more flexible than Zapier or Make for complex logic
- JavaScript expressions and custom nodes let you escape any limitation
- Cloud option for teams who don't want to operate the server
What doesn't
- Initial setup requires developer time (1+ day for serious workflows)
- Self-hosted version requires ongoing maintenance — patches, backups, monitoring
- Higher learning curve than Zapier or Lindy for non-technical operators
- Visual builder gets cluttered for very large workflows (20+ nodes)
- Pure agentic loops without integrations are better served by dedicated harnesses (OpenClaw, Paperclip)
Stack AI
What works
- Best-in-class document ingestion and RAG pipeline
- Strong enterprise data connectors (Notion, Confluence, Google Drive)
- SOC 2 compliant
- Good UI for non-technical configuration
What doesn't
- Expensive at team scale ($199+/month)
- Limited flexibility for multi-step process automation
- Weaker for external-facing or trigger-based workflows
Which to pick
We'd default to n8n (4.5/5 vs 3.5/5) for most builders. Pick Stack AI if you fit its best-for case specifically: ops teams who want ai agents over their internal documents — sops, contracts, product specs, notion wikis.
Honest middle: most serious operators end up using more than one tool. If you're early in your AI agent journey, our five-question picker recommends a starting platform from your specific situation.
