Could you build this?
Yes This is a testing harness and arena UI that sends prompts to two different LLM endpoints/tool-configurations, collects the tokens/diffs, and displays a side-by-side comparison with local storage logging. Standard web UI and API orchestration like this can be built with an AI assistant in days.
