💡 What You Will Learn
A self-hosted chatbot gives you a private ChatGPT. We compare Open WebUI, LibreChat, NextChat and Jan with real GitHub star data.
Every week another company ships data to a model you do not control. A self-hosted chatbot fixes that: your conversations, your model, your server.
The Contenders
Open WebUI (148,123 stars) is the default pick: polished ChatGPT-grade UI, RAG on your documents, multi-user, works with Ollama (177,874 stars) and any OpenAI-compatible API. LibreChat (41,704 stars) wins on provider breadth - GPT, Claude, Gemini, local - in one interface. NextChat (88,588 stars) is the lightweight deployment for personal use. Jan (43,864 stars) is desktop-first for single machines.
Deployment Reality
All four run in Docker in under 15 minutes. The common pattern: Ollama serves models, one of these serves the UI, n8n (199,484 stars) or LangChain (143,505 stars) adds automation. A mini PC with 32GB RAM handles a 7-14B model comfortably for a small team.
FAQ
Q: Which is easiest for a beginner?
A: Open WebUI - the install is one Docker command and the default settings just work with Ollama.
Q: Can my family use it too?
A: Yes - Open WebUI and LibreChat both have multi-user accounts; put it behind your home VPN or a simple auth proxy.
