My Guess Going In

My initial guess was clear: AgentKit won't "kill" n8n. They are built for completely different purposes and users, addressing different needs in the world of AI automation. The upcoming testing aimed to prove this right.

The Testing Framework: 6 Categories, Scored Objectively

Each platform was scored 1-10 across six critical categories, with the individual scores summed up at the end. However, it's important to remember that raw scores don't tell the whole story; context matters far more than just points.

The goal is to understand where each platform excels.

Category 1: Ease of Use (First Impressions Matter)

The Test: How quickly can a complete beginner build their first AI automation?

AgentKit: The Gentle Introduction

• Getting Started: Search "OpenAI agent builder" and navigate to the OpenAI platform. It's designed for immediate access.

• What You See: A clean, minimal interface that says "Create a workflow". This immediately tells you what kind of solution you're building.

• The Workflow:

  • It starts with an undeletable "Start" node (every workflow needs a trigger).

  • You simply drag connections between nodes.

  • AI agent configuration uses straightforward dropdowns.

  • The left sidebar presents only 5 core logic operations: If/Else, While, User Approval, Transform and Set State.

• First Task Test (Web Search): Connecting to the internet for a web search is incredibly simple: click the plus for tools, select "web search" and you're done. No API keys, no complex configuration.

• The Experience: AgentKit is far less intimidating than n8n. A working web-search agent can be built in under 2 minutes.

• Verdict: 8/10 - Incredibly beginner-friendly, perfect for quick starts.

n8n: The Power User's Paradise (With a Learning Curve)

• Getting Started: Creating a new workflow immediately presents a multitude of options and configurations.

• What You See: A complex interface with hundreds of tools, variables and connections that can initially confuse beginners. You might even encounter error messages before you start (because no chat model is connected yet).

• First Task Test (Web Search): Connecting to the internet requires adding an AI agent node, choosing from hundreds of different tools, potentially needing custom HTTP requests and obtaining API keys for both web search and the chat model.

• The Experience: Much more intimidating initially but infinitely more powerful and customizable once understood.

• Verdict: 6/10 - A steeper learning curve but offering significantly more capability.

Running Score: AgentKit 8, n8n 6.

Category 2: Triggers (How Your Automations Start)

The Test: What can actually kick off your automations and how flexible are those starting points?

AgentKit: The Chat-Only Limitation

• Available Triggers: Limited solely to the "Start" option, meaning interactions are almost exclusively chat-based.

• What This Means:

  • You can only trigger agents by talking to them directly in the preview chat.

  • There are no scheduled triggers, no app event triggers and no general web-based triggers.

• The API Workaround: While technically possible to trigger via TypeScript or Python SDK, it's not an intuitive or user-friendly solution.

• Example Limitation: If you want an agent to respond to new emails, there's no native "Gmail trigger on new message received". You'd need complex workarounds or external systems.

• The Strategic Problem: The most valuable automations often run silently in the background without a person having to start them. AgentKit's design forces human interaction for most use cases, limiting its utility for truly autonomous business processes.

• Verdict: 5/10 - Severely limited trigger options, heavily favoring conversational interaction.

n8n: The Trigger Paradise

• Available Triggers: Offers hundreds of native triggers across virtually every major platform.

  • Gmail: Eight different triggers (e.g., new message, bot mentioned, file shared).

  • Slack: Multiple event types.

  • Google Drive: Triggers for file changes, additions or permission modifications.

  • Webhooks: Any CRM or external system can easily trigger n8n workflows.

  • Scheduled Triggers: Time-based automations for recurring tasks.

• The Strategic Advantage: n8n allows you to build systems that scale with business growth. Lead nurturing systems become more valuable as you acquire more leads and email response systems handle increasing volume as your business expands. The most powerful automations are often the ones you forget are running until you see their impactful results.

• Verdict: 10/10 - Virtually unlimited trigger possibilities, supporting truly autonomous and scalable workflows.

Running Score: AgentKit 13, n8n 16.

Category 3: Agent Tools (What Your Agents Can Actually Do)

  • Zapier MCP Servers: Ability to connect to Zapier's vast ecosystem via their MCP integration.

  • Custom n8n Workflow Connections: Allows linking to specialized n8n workflows.

• The Experience: Super easy to connect the tools that are available but the overall selection is limited.

• MCP Limitation: Everything has to be exposed as an MCP server, which can reduce the universe of possible direct connections compared to standard API integrations.

• Verdict: 5/10 - Limited in number but exceptionally easy to use for the existing integrations.

n8n: The Integration Universe

• Available Tools:

  • 500+ Native Integrations: Connecting to virtually any tool you can imagine.

  • HTTP Request Tool: The ultimate connector, allowing you to interface with any service that provides API documentation.

  • Sub-workflow Capabilities: Enables the creation of modular, reusable agent systems.

• The Team Advantage: n8n allows you to build complex agent systems where different agents specialize in different tasks (e.g., a Main Agent orchestrating an Email Agent, a Calendar Agent and an Analysis Agent). Each sub-agent can have its own specialized tools, creating a completely modular and reusable architecture.

For example, a single "email agent sub-workflow" can be reused across 100 different automations without rebuilding it.

• The HTTP Superpower: If a service has an API, n8n can connect to it. Period. This provides unparalleled flexibility.

• Verdict: 10/10 - Virtually unlimited possibilities for integration and customization.

Running Score: AgentKit 18, n8n 26.

Category 4: Model Support (AI Brain Options)

The Test: What AI models can power your agents and how much control do you have over their settings?

• Built-in Configuration: It provides easy toggles for adjusting how much the AI thinks, how much it talks and which tools it uses. It also features built-in chat history management.

• The Advantage: Everything is pre-configured within your OpenAI environment, eliminating the need for API key hunting and complex setup.

• The Limitation: You are completely locked into OpenAI's ecosystem. There is no support for other major models like Anthropic's Claude, Google's Gemini or the ability to run local models for privacy.

• Verdict: 6/10 - Excellent OpenAI integration but a limited choice of underlying AI models.

n8n: The Model Democracy

• Available Models: It offers true flexibility, allowing you to choose your own AI adventure.

  • Anthropic (Claude family).

  • Azure OpenAI.

  • AWS Bedrock.

  • Cohere.

  • OpenRouter (providing access to hundreds of models from various providers).

  • Local models (if self-hosting for complete privacy and cost control).

• The Strategic Flexibility: This allows you to select the best model for each specific task (e.g., Claude for writing, GPT-5 for reasoning, Gemini for specific multi-modal use cases). It also enables significant cost optimization by routing tasks to the most cost-effective provider.

• Configuration Control: Provides full control over critical model parameters like temperature, top-p and frequency penalty.

• Verdict: 10/10 - Complete model flexibility and choice, enabling optimal performance and cost management.

Running Score: AgentKit 24, n8n 36.

Category 5: UI/Chat Components (User Experience)

The Test: How do users actually interact with your agents and how professional and customizable are the chat windows?

AgentKit: The Frontend Champion

Final Score: AgentKit 40, n8n 51

Beyond the Scores: The Real Differences

While the scores provide a quick look, the real differences between AgentKit and n8n are in their core ideas and how they feel to use.

Pricing Reality Check

• AgentKit: Still in active development, so pricing is not finalized. It is currently free to access but you pay for the underlying OpenAI model usage based on tokens.

• n8n: Has an established pricing model with a generous free self-hosted option and various cloud plans for those who prefer managed services.

Evaluation and Debugging

• AgentKit Strengths: Offers useful evaluation tools with datasets, trace grading capabilities and prompt optimization features.

• AgentKit Weaknesses: It can be challenging to visualize the data flow between nodes, making complex workflows difficult to debug. Variables and data movement are not always visually clear.

• n8n Strengths: It provides a very clear picture of how data moves, with input, configuration and output clearly shown for each node. It has extensive execution history and debugging tools, making troubleshooting simple and intuitive.

• The Debugging Experience: In n8n, when something breaks, you can immediately see where and why. In AgentKit, debugging can feel like hunting through logs and variables with less visual guidance.

Community and Learning

• Data sovereignty isn't a primary concern and you trust OpenAI with your business-critical workflows.

• Quick testing is very important for rapidly creating and comparing different agent ideas.

Choose n8n When:

• Flexibility across multiple AI providers is important and you want the ability to use the best model for each specific task.

• Cost optimization across different AI providers is a strategic goal and avoiding vendor lock-in is critical.

• Complex workflow automation beyond simple chat is required, involving multi-step business processes and integration with dozens of business tools.

• Background automations that run without human intervention are essential.

• Cost control through self-hosting matters, especially if you have strict data sovereignty or compliance requirements.

• Complete data and infrastructure control is required for enterprise security or custom compliance needs, including integration with existing infrastructure.

• You need to connect to literally anything- unusual or custom integrations, legacy system connections or highly specific business tool requirements.

The Strategic Mindset: Beyond Tools

It's easy to get caught up in the hype and endless debates about which tool is "better". But a strategic mindset shifts the focus from tools to problems.

The Questions That Matter

Stop asking: "What's going to drop next?", "What tool should I learn?" or "Am I taking a huge risk choosing this platform?"

Start asking:

• When is AI truly valuable versus when is it not?

• How can I save time and solve real business problems?

• What core business problem am I actually addressing with this automation?

The truth about client work is simple: businesses don't choose you because of your specific tool. They choose you because you know how to deliver tangible results that save money, save time and increase focus.

The Winning Mindset

• Don't get stuck on one tool: Focus on solving the real problem. It doesn't matter how you get there.

• Focus on outcomes, not features: The client cares about measurable results, not whether you used AgentKit or n8n.

• Build problem-solving skills, not tool dependency: AI tools will keep evolving. Strong problem-solving frameworks are permanent and transferable.

The Real Future: Coexistence, Not Competition

The prediction is clear: both AgentKit and n8n will succeed because they serve different, yet equally vital, needs in the rapidly expanding AI automation market.

• AgentKit will dominate: For quick internal automations within OpenAI-heavy teams, customer-facing chat applications, rapid prototyping and proof-of-concepts and for non-technical teams who need immediate, visually polished results.

• n8n will dominate: For complex enterprise automations, multi-platform integrations, custom business process automation and for teams that demand complete control and flexibility over their data and infrastructure.

The market is big enough for both. Different problems require different solutions and having a diverse toolkit is key.

Your Next Steps

• If You're New to AI Automation: Start with AgentKit to understand the basics quickly, then graduate to n8n when you need more power and flexibility.

• If You're Building a Business: Learn both platforms. Different clients will have different needs and being platform-agnostic makes you a more valuable and adaptable solution provider.

• If You're in Enterprise: Evaluate both platforms based on your specific requirements: data sovereignty, complex integration needs and internal team capabilities.

The Bottom Line

Final scores: AgentKit 40, n8n 51.

But scores don't tell the whole story. AgentKit is incredible at what it does- making AI agents accessible to everyone with remarkable ease. n8n is incredible at what it does- giving power users unlimited flexibility and control.

The real winner? Anyone who focuses on solving problems instead of getting caught up in arguments about tools.

Both platforms have bright futures. The AI automation space is exploding and there's room for multiple approaches to serve different needs.

My advice: Stop worrying about which tool will "win" and start building solutions that matter. The businesses that succeed won't be the ones with the "best" tools- they'll be the ones that solve real problems most effectively.
