+Current hosted-plan prices and usage limits can change, so confirm them on the official [Sim pricing](https://www.sim.ai/pricing), [n8n pricing](https://n8n.io/pricing/), and [OpenAI API pricing](https://openai.com/api/pricing/) pages before making a cost comparison.
+
+## How do agent-first, automation-first, and OpenAI-platform-first architectures differ?
+
+[Sim is agent-workflow-first](https://docs.sim.ai/agents), [n8n is business-automation-first](https://docs.n8n.io/), and [OpenAI AgentKit is OpenAI-platform-first](https://developers.openai.com/api/docs/guides/agents). That starting point determines what each product makes easiest to design, inspect, and operate.
+
+| Architecture decision | [Sim](https://docs.sim.ai/agents) | [n8n](https://docs.n8n.io/) | [OpenAI AgentKit](https://developers.openai.com/api/docs/guides/agents) |
+|---|---|---|---|
+| Starting point | Design an AI-agent workflow on a visual canvas | Connect applications and automate a business process | Build an agent around OpenAI platform primitives |
+| Agent and automation balance | Agentic and deterministic blocks share one workflow | Deterministic automation is the foundation, with AI added through nodes | Agent behavior is central; conventional automation often requires application code or external services |
+| Model strategy | Workflows can use different model and tool providers | AI services connect through nodes and credentials | Optimized for OpenAI models and services |
+| Infrastructure boundary | Cloud or Apache 2.0 self-hosting | Cloud or self-hosting under the Sustainable Use License | Application and SDK code can run in your environment, while OpenAI-managed services remain hosted |
+| Best organizational fit | Product, AI, and engineering teams sharing a visual system | Operations and engineering teams automating many SaaS tools | Developer teams committed to OpenAI's platform |
+
+The distinction is architectural rather than cosmetic. A visual canvas does not make three products equivalent when one centers agent reasoning, another centers event-driven application automation, and the third centers a particular hosted model platform.

 n8n provides deployment control under its more restrictive source-available license. OpenAI's tooling intentionally optimizes for the OpenAI ecosystem, making it convenient for OpenAI-first teams but less suitable when provider independence is a primary requirement.
 
+## Which platform has the strongest integration strategy?
+
+n8n has the strongest integration-oriented position: its documentation catalogs both [built-in and community nodes](https://docs.n8n.io/integrations). [Sim emphasizes composing agent-centered systems](https://docs.sim.ai/agents/choosing) from model calls, tools, deterministic blocks, APIs, and webhooks. [OpenAI's tooling emphasizes tools connected to its agent runtimes and platform services](https://developers.openai.com/api/docs/guides/agents).
+
+A connector count should not decide the purchase by itself. Test the exact systems, authentication methods, actions, data shapes, and failure behavior the production workflow requires. Native integrations generally reduce maintenance, while HTTP requests, webhooks, MCP servers, and custom tools can cover gaps at the cost of additional implementation work.
+
+For integration-heavy back-office automation, n8n is often the natural starting point. For agent-centered systems in which integrations serve model-driven behavior, Sim may be the better architectural fit. For applications centered on OpenAI-managed capabilities, OpenAI's agent stack provides the most direct path.

 ## How should you compare the cost of Sim, n8n, and OpenAI AgentKit?
 
 Compare total production cost rather than one advertised subscription price. This September 2026 comparison deliberately does not reproduce changing plan prices or limits; verify current terms on each vendor's official pricing page.
