## Overview
|
||
|
||
Did you know Open WebUI can connect to almost **anything**—not just OpenAI-compatible APIs?
|
||
|
||
Thanks to **Pipe Functions**, you can bring in services that don’t support the OpenAI API (like **Anthropic**, Home Assistant, Google Search, or *any* Python codebase). No restrictions on LLMs or AI models: if you can automate it in Python, you can turn it into a plugin for Open WebUI!
|
||
|
||
This guide walks you through setting up your first Pipe Function, using the [Anthropic Pipe](https://openwebui.com/f/justinrahb/anthropic) plugin as an example.
|
||
|
||
## What are Pipe Functions?
|
||
|
||
Pipe Functions are “bring-your-own-model (or tool)” plugins:
|
||
|
||
- **Act like models**: They show up as selectable models in your Open WebUI sidebar.
|
||
- **Flexible**: Integrate with *any* backend, API, or workflow—no OpenAI compatibility required.
|
||
- **No LLM required**: You can build plugins for search, home automation, weather, databases, or whatever you like.
|
||
- **Pure Python**: All logic is Python code that runs *directly inside* your WebUI (so be cautious with what you enable!).
|
||
|
||
## Step 1: Find a Pipe Function to Try
|
||
|
||
Functions are powerful tools, and the community has created thousands of them! You can browse, search, and import them directly from our community hub.
|
||
|
||
:::info Community Account Required
|
||
To search and import functions directly from **[Open WebUI Community](https://openwebui.com/search)**, you must be logged in with a registered community account.
|
||
:::
|
||
|
||
1. Go to **[Open WebUI Community Search](https://openwebui.com/search)**.
|
||
2. Explore the library! You can find functions for:
|
||
* **New Providers**: Anthropic, Google Gemini, Groq.
|
||
* **Tools**: Web Search, Calculator, Home Assistant control.
|
||
* **Utilities**: Auto-tagging, content filtering, and more.
|
||
3. **Pro Tip**: Even if you don't find exactly what you need, you can use existing functions as **templates** to build your own!
|
||
|
||
For this guide, let's try integrating **Anthropic** (Claude models):
|
||
|
||
1. Locate the [Anthropic Pipe](https://openwebui.com/f/justinrahb/anthropic) function.
|
||
2. Click **Get**.
|
||
|
||
|
||
|
||
## Step 2: Import the Function to Open WebUI
|
||
|
||
A modal will appear:
|
||
|
||
1. Enter your Open WebUI URL (e.g., `http://localhost:3000`) in the prompt.
|
||
2. Click **Import to Open WebUI**.
|
||
|
||
|
||
|
||
You’ll be redirected **directly to the Functions Editor** within your running instance of Open WebUI.
|
||
|
||
## Step 3: Review & Save
|
||
|
||
- You’ll see all of the Pipe Function’s Python code and configuration.
|
||
- **Important:** Functions run arbitrary Python! Review the code for safety, and only install from sources you trust.
|
||
- If you’re happy with the code, click **Save** to add it to your instance.
|
||
|
||
|
||
|
||
## Step 4: Enable the Function
|
||
|
||
Your new Pipe Function is now available, but **must be enabled**:
|
||
|
||
1. Switch the toggler to enable the function.
|
||
|
||
|
||
|
||
## Step 5: Enter any Required API Keys via Valves
|
||
|
||
Some functions need credentials (like Anthropic’s API key):
|
||
|
||
1. Click on the Gear icon next to the switch to open the **Valves** configuration.
|
||
2. Input your required API key(s) for the Pipe Function.
|
||
|
||
|
||
|
||
## Step 6: Start Using Your New Plugin!
|
||
|
||
- The new function now appears as a selectable “model” in the chat interface.
|
||
- Select `Anthropic` (or whatever you installed), and start chatting!
|
||
|
||
|
||
|
||
## 🎉 That’s It—You’re Plugged Into Anything!
|
||
|
||
- Pipe Functions open Open WebUI to *any* API, model, or automation—not just OpenAI-compatible endpoints.
|
||
- Think beyond LLMs: Integrate tools, APIs, local scripts, or your entire smart home.
|
||
|
||
## ⚠️ Security Notes
|
||
|
||
- **Always** review function code before enabling.
|
||
- Only use plugins from trusted sources.
|
||
- You have the power to enhance (or break!) your WebUI—use responsibly.
