Open WebUI + Ollama Stack

Open WebUI + Ollama Stack 

This is the meaty one, Open WebUI is straightforward, there are several other options not covered here.

Ollama is now serving insanely powerful open source models, and you can host them on your own hardware (if you built before the current chip pricing situation).

For people who want to minimize their costs after hardware investment, this is a very viable option. If you're employer is still letting you tokenmax, have at it, buster ;) it's not going to last forever.

The full stack, end to end: what Open WebUI and Ollama each do, how Docker packages and runs both, wiring them together, where configuration and security defaults live, GPU acceleration and quantization for performance, and the maintenance habits that prevent the most common support problems.

For a self-hoster setting this stack up for the first time—you're comfortable with a terminal, just new to this specific combination.

16 formative questions along the way, a 14-question final assessment, 75% to pass.
