// EDITOR'S TAKE
LibreChat is the closest in spirit, with one web UI over many providers, conversation branching and shared prompts, and it is the easiest of these to hand to a team. Open WebUI is more capable overall with RAG, tools and user management but is a heavier install aimed at local models, while Jan and cherry-studio are desktop apps rather than the always-open browser tab T3.chat gives you.
