Head-to-head
n8n vs Vertex AI Agent Builder.
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 Vertex AI Agent Builder is a enterprise platform.
| n8n | Vertex AI Agent Builder | |
|---|---|---|
| Rating | 4.5 / 5 | 3.5 / 5 |
| Category | Workflow builder | Enterprise platform |
| Tech level | low code | developer |
| Open source | Yes | No |
| Pricing | Open-source self-hosted (free). Cloud plans from $24/month. | Usage-based on Google Cloud: per-token Gemini model costs + Vertex AI infrastructure. Free tier credits available for new accounts. |
| Best for | Teams with at least one developer who need flexible, powerful workflow automation with AI agents built in — and want the option of full data control. | Engineering teams on Google Cloud who want to build agents using Gemini's long-context capabilities and integrate directly with BigQuery, Cloud Storage, and Google Workspace. |
| Not for | Teams with zero technical resources. Initial setup requires someone comfortable with a server. | Teams not on Google Cloud — Vertex's value proposition is integration depth that doesn't transfer. Teams that want model flexibility — Vertex is Gemini-only. |
