Hey Product Hunt! 👋 LMRing is an open-source AI model comparison platform — think of it as a self-hostable LMArena (Chatbot Arena). I built this because existing AI comparison tools are either closed-source, limited to text-only comparisons, or don't let you bring your own models. As someone who constantly evaluates different LLMs, I wanted a tool that's transparent, extensible, and truly yours. What makes LMRing stand out: → Compare up to 4 AI models side-by-side with real-time streaming → Unique web development comparison — see AI-generated code rendered live in the browser → Video output comparison across models → 50+ providers supported, plus custom OpenAI-compatible endpoints → ELO-based leaderboard powered by real community votes → Fully self-hostable — deploy on your own infrastructure It's completely open source and free to get started. I'd love to hear which AI models you're currently using and what comparison features matter most to you! Try it out → https://lmring.com/
