A self-hosted ChatGPT setup needs two parts: a **model runtime** and a **chat interface**.

| Tool | Type | Licence | Best for |
|---|---|---|---|
| [Open WebUI](https://ai.andreiturcea.com/tool-open-webui.html) | Chat UI | BSD-3 | ChatGPT-style UI for Ollama and APIs |
| [LibreChat](https://ai.andreiturcea.com/tool-librechat.html) | Chat UI | MIT | Multi-provider chat with agents |
| [AnythingLLM](https://ai.andreiturcea.com/tool-anything-llm.html) | RAG app | MIT | Chat with your documents |
| [Jan](https://ai.andreiturcea.com/tool-jan.html) | Desktop app | Apache-2.0 | Offline, no server |
| [Ollama](https://ai.andreiturcea.com/tool-ollama.html) | Runtime | MIT | One-command local models |

## What does a typical self-hosted stack look like?

Laptop: Jan, or Ollama + Open WebUI. Small team on a VPS: Ollama or [vLLM](https://ai.andreiturcea.com/tool-vllm.html) + LibreChat or Open WebUI, with [Langfuse](https://ai.andreiturcea.com/tool-langfuse.html) for observability. See [Ollama vs llama.cpp vs vLLM](https://ai.andreiturcea.com/ollama-vs-llama-cpp-vs-vllm.html).

## Frequently asked questions

### What is the easiest self-hosted ChatGPT alternative?

For a single machine, Ollama to run models plus Open WebUI as the chat interface is the most common setup. Jan is a desktop app if you do not want Docker.

### Do I need a GPU?

Not for small quantised models: llama.cpp and Ollama can run them on CPU, but slowly. For larger models or several users, a GPU makes a big difference.

### Can I use cloud APIs from the same interface?

Yes. Open WebUI, LibreChat and AnythingLLM can connect to OpenAI-compatible APIs as well as local models.
