title: "Starting with OpenAI-Compatible Servers"
|
||
|
||
---
|
||
|
||
## Overview
|
||
|
||
Open WebUI isn't just for OpenAI/Ollama/Llama.cpp—you can connect **any server that implements the OpenAI-compatible API**, running locally or remotely. This is perfect if you want to run different language models, or if you already have a favorite backend or ecosystem. This guide will show you how to:
|
||
|
||
- Set up an OpenAI-compatible server (with a few popular options)
|
||
- Connect it to Open WebUI
|
||
- Start chatting right away
|
||
|
||
## Step 1: Choose an OpenAI-Compatible Server
|
||
|
||
There are many servers and tools that expose an OpenAI-compatible API. Here are some of the most popular:
|
||
|
||
- [Llama.cpp](https://github.com/ggml-org/llama.cpp): Extremely efficient, runs on CPU and GPU
|
||
- [Ollama](https://ollama.com/): Super user-friendly and cross-platform
|
||
- [LM Studio](https://lmstudio.ai/): Rich desktop app for Windows/Mac/Linux
|
||
- [Lemonade](https://lemonade-server.ai/): Fast ONNX-based backend with NPU/iGPU acceleration
|
||
|
||
Pick whichever suits your workflow!

#### 🍋 Get Started with Lemonade
|
||
|
||
Lemonade is a plug-and-play ONNX-based OpenAI-compatible server. Here’s how to try it on Windows:
|
||
|
||
1. [Download the latest `.exe`](https://github.com/lemonade-sdk/lemonade)
|
||
2. Run `Lemonade_Server_Installer.exe`
|
||
3. Install and download a model using Lemonade’s installer
|
||
4. Once running, your API endpoint will be:
|
||
|
||
```
|
||
http://localhost:8000/api/v0
|
||
```
|
||
|
||
|
||
|
||
See [their docs](https://lemonade-server.ai/) for details.

||
## Step 2: Connect Your Server to Open WebUI
|
||
|
||
1. Open Open WebUI in your browser.
|
||
2. Go to ⚙️ **Admin Settings** → **Connections** → **OpenAI Connections**.
|
||
3. Click ➕ **Add Connection**.
|
||
|
||
- **URL**: Use your server’s API endpoint (for example, `http://localhost:11434/v1` for Ollama, or your own Llama.cpp server’s address).
|
||
- **API Key**: Leave blank unless required.
|
||
|
||
4. Click Save.
|
||
|
||
:::tip
|
||
|
||
If running Open WebUI in Docker and your model server on your host machine, use `http://host.docker.internal:<your-port>/v1`.
|
||
|
||
:::
|
||
|
||
##### **For Lemonade:** When adding Lemonade, use `http://localhost:8000/api/v0` as the URL.
|
||
|
||
|
||
|

|
||
|
||
## Step 3: Start Chatting!
|
||
|
||
Select your connected server’s model in the chat menu and get started!
|
||
|
||
That’s it! Whether you choose Llama.cpp, Ollama, LM Studio, or Lemonade, you can easily experiment and manage multiple model servers—all in Open WebUI.
