Frequently Asked Questions (FAQ)

1. Which platform is better for privacy: Open WebUI or LibreChat?

For maximum privacy, Open WebUI running local models via Ollama is superior. When using local models, your prompts and data never leave your machine. LibreChat, while self-hostable (giving you control over your chat history data), typically sends your prompts and conversations to third-party LLM API providers (e.g., OpenAI, Google) for processing, meaning your data is subject to their respective privacy policies.

2. Can I use both Open WebUI and LibreChat?

Yes, absolutely! They serve different primary purposes. You could use Open WebUI for all your local, private AI interactions and experiments, and then use LibreChat for testing various cloud-based LLMs, comparing their outputs, or collaborating with a team on projects that require diverse API access. They are complementary rather than mutually exclusive.

3. Do I need advanced technical skills to set up Open WebUI or LibreChat?

A basic understanding of Docker and command-line interfaces is highly recommended for both. For Open WebUI, knowledge of setting up Ollama and managing local models (especially regarding hardware requirements for GPU acceleration) is beneficial. For LibreChat, configuring multiple API keys and environment variables requires some technical comfort. However, both projects have active communities and decent documentation to guide users through the setup process.

4. Which platform supports the most AI models?

LibreChat generally supports a wider variety of external API models from different commercial providers (OpenAI, Anthropic, Google, Azure, etc.) directly out-of-the-box. Open WebUI excels in supporting local models through its deep integration with Ollama. When considering the sheer number of accessible models, especially via a unified API, LibreChat, particularly when combined with a platform like XRoute.AI, offers the broadest spectrum of choices from numerous providers through a single endpoint.
