💡 What You Will Learn
An open source LLM platform gives you a ChatGPT-like interface for local models. We compare Open WebUI, LobeChat, Jan and LibreChat with real stars.
Running a model locally is the easy half; giving your family or team a clean interface is the hard half. An open source LLM platform solves exactly that - and the 2026 options are shockingly polished.
The Platforms
Open WebUI (open-webui/open-webui, 148,020 stars) is the default choice: ChatGPT-grade UI for Ollama and OpenAI-compatible APIs, with RAG, web search, and multi-user accounts. LobeChat (lobehub/lobe-chat, 81,314 stars) shines at multi-model conversations and plugin ecosystem. Jan (janhq/jan, 43,864 stars) is the desktop-first option - install, download a model, chat offline. LibreChat (danny-avila, 41,704 stars) offers the broadest provider support with an API-first design.
Deployment: Open WebUI in Docker behind your LAN - five minutes to a private ChatGPT for your whole household. LobeChat adds vision and TTS plugins; Jan is the pick for a single laptop with no server. All four work with Ollama (177,902 stars) out of the box.
