Sat, 11 Apr 2026 07:00:00 +0000

Every week, a client asks me some version of this question: “Should we build our own AI agent or just use [product]?”

The answer is never simple, but after building custom AI agent systems for production use, I have a clear framework for when each path makes sense.

I integrate LLM APIs into business automation systems. Content pipelines, document processing, customer communication flows, data enrichment. Not chatbots. Production systems that run unattended and need to work every time.

The Short Version

OpenAI has the ecosystem. Claude has the output quality. Both work. Your choice depends on what you are building and what failure mode you can tolerate.

Make.com vs n8n: The Core Difference

Make.com is a managed platform. n8n is infrastructure you own.
