Open WebUI pros and cons

Polished, feature-rich ChatGPT-style UI and the most popular front end for Ollama
Works with local models and any OpenAI-compatible API, mixing both freely
Built-in multi-user accounts, chat history, RAG, and a plugin/function system
Actively and rapidly developed with frequent releases
Source-available, not strict open source: a branding clause restricts removing Open WebUI branding above 50 users
Larger or commercial deployments may need written permission or an enterprise license
Like all front ends, it needs you to supply models (e.g. Ollama) or API keys

Jan pros and cons

Runs LLMs fully offline on your own hardware, so conversations stay private by default
Simple point-and-click model downloads from Hugging Face, no command line required
Genuinely open source under the permissive Apache-2.0 license
Exposes an OpenAI-compatible local API server (localhost:1337) for wiring into other apps
Local model quality depends heavily on your RAM and GPU; small models are far weaker than ChatGPT or Claude
Decent performance effectively needs 16GB+ RAM and ideally a supported GPU
Still maturing, with a fairly high open issue count and occasional rough edges
