I built a local AI stack with 5 Docker containers, and now I'll never pay for ChatGPT again

A personal walkthrough of a 5-container Docker stack for running AI entirely on local hardware. The setup includes Ollama for model management (supporting 7B–20B parameter models), Open WebUI for a ChatGPT-like chat interface, n8n for workflow automation, AgenticSeek for multi-step agentic tasks, and SearXNG as a private metasearch engine. The author runs this on an RTX 5070 with 32GB RAM, eliminating cloud subscriptions and keeping all data private.
