Show HN: I Built an AI Chat Arena

I started testing prompts more in the past few days, thought building this UI to test prompt and compare the response from multiple models.

This is a BYOK app, support models from OpenRouter, OpenAI, Claude, Gemini, Groq, Azure and custom models. You'll need to 1. Config your AI service 2. Create a new arena 3. Add the models you want to test

Then enter the prompt and click Send icon to see the result
