Self-hosting LLMs is no longer just for infra teams. With tools like Ollama and Open WebUI, you can run capable models on your own machine, keep conversations private, and avoid unpredictable API bills. For developers, founders, and small teams, this setup gives you more control without adding much operational complexity.
In this guide, you will build a local AI stack using Ollama + Open WebUI on Docker. By the end, you will have a ChatGPT-style interface running on your system, with an optional secure way to share it outside your local network.
