Minimal Viable AI Platform

Creating your own AI platform sounds like a job for a funded team with a matching cloud bill. It is not. A handful of open source tools, combined into a single Docker Compose file, gives you a working AI platform on one machine. The platform has five layers: agentgateway as the gateway with one API for any model, keys and cost tracking; Open WebUI as the chat interface; n8n for automation and agents that take real actions; Ollama for private local models; and Langfuse for request tracing. From there we look at how to grow it with RAG, authentication and scaling without bolting on disconnected tools. Not perfect, but a valid starting point for organizations of any size. No enterprise budget needed.
