Have you ever wished you could talk to ChatGPT, Claude, and Meta AI all in the same chat window? Imagine asking one AI model a question, then instantly switching to another to verify the answer—without bouncing between apps or browser tabs.

That’s the magic of Open WebUI, a free, open-source tool that makes this possible. And thanks to House of Foss, deploying and managing Open WebUI has never been easier—even if you’re not a tech expert.

👉 In this blog, we’ll explore what Open WebUI is, how it works, its powerful features, and how House of Foss makes running it effortless—even for non-developers. Plus, we’ll show you how to get started and save big on AI costs.

Curious how it all works? Check out this YouTube video here → for a great walkthrough! Let’s dive into how this revolutionary duo is transforming the world of multi-LLM chat interfaces.

What is Open WebUI?

Open WebUI is a powerful, open-source chat application that lets you connect and chat with multiple Large Language Models (LLMs) in one place. Whether you’re using OpenAI’s GPT-4, Claude, Meta AI, or open-source models like Ollama or Gemma 3.1, Open WebUI allows you to:

✅ Switch between AI models seamlessly

✅ Keep a single conversation thread while changing LLMs

✅ Connect any model that supports OpenAI-compatible APIs

✅ Run your own instance for privacy and data security


No wonder it’s earned over 100,000 stars on GitHub. It’s a game-changer for developers, researchers, and businesses who need flexibility and control over their AI tools.

Powerful Features for Serious AI Work

Beyond just chatting, Open WebUI comes packed with advanced capabilities:

  • Tool functions for enhanced interactions

  • Workspaces for organizing your projects

  • Code execution directly in the chat

  • Document extraction for handling text-heavy data

  • Evaluation tools to test and compare LLM performance

And the best part? It’s 100% free and open source.

House of Foss Makes It Simple

House of Foss is a marketplace that makes deploying open-source applications as easy as installing an app on your smartphone. It’s built to make open-source software accessible to everyone, not just developers.

Here’s how simple it is to run Open WebUI on House of Foss:

  1. Create a workspace after signing up.

  2. Search for Open WebUI in the marketplace.

  3. Choose how many monthly active users you expect.

  4. Name your application and hit Launch.


In minutes, you’ll receive a private, secure link to your Open WebUI instance—no server headaches, no manual configuration. Plus, you pay only for the minutes you actually use.

 A Real-Life Example: Multi-LLM Conversation in Action

In the video linked above, It is demonstrated how Open WebUI can ask GPT-4.1 a fun fact about the Roman Empire. Then, in the same chat, they switched to Gemma 3.1—a lightweight, open-source LLM—to verify the fact.

No copy-pasting conversations, no toggling between tools. Everything happened fluidly in one unified chat interface.

And adding new models is incredibly easy. Want to test out Phi-3 or any other model? Just click Install in Open WebUI’s panel, and you’re ready to go.

Why This Matters for Businesses and Developers

If your team works with multiple LLMs—testing outputs, comparing performance, or managing costs—Open WebUI is a total game-changer. It helps you:

  • Save time switching between different models

  • Keep your experiments and chats in one place

  • Maintain full control over data privacy and security


Plus, using Open WebUI via House of Foss can help businesses save up to 60% on SaaS costs by leveraging free, open-source alternatives for LLMs, ERPs, analytics, project management, and more.
