What is fox-ai-roundtable?

Fox AI Roundtable is a tiny local web app that sends the same question to Claude, Codex (GPT), and Antigravity (Gemini) at the same time, side by side. It works entirely through the command line tools you already have installed and logged into for each of those assistants, so it uses your existing subscriptions and needs no separate API key. Before running it, all three command line tools need to be installed and signed in separately: Claude Code for Claude, the Codex CLI for GPT, and Antigravity's own CLI for Gemini. A recent version of Node.js is also required, and the app itself has no other dependencies. Once set up, starting the app with a single Node command opens a local page where you type a question and submit it, and all three assistants answer at the same time, each shown as soon as it finishes along with how long it took. The tool keeps a separate ongoing conversation with each assistant so you can continue asking follow up questions, and a New Conversation button clears all three histories at once. Checkboxes let you limit a question to only some of the assistants, and a model menu next to each one lets you pick things like Claude's Sonnet, Opus, or Haiku, Codex's reasoning effort setting, or which Gemini model Antigravity uses. You can also attach an image, and all three assistants will look at it when answering. Responses render as Markdown and the interface supports dark mode, switching automatically between Traditional Chinese and English based on your system language, with a manual switch available too. Under the hood, a small dependency free Node server runs each assistant's command line tool as a separate process and resumes the same conversation thread on each follow up message. For safety, the server only listens on your own machine, each CLI runs inside a dedicated empty folder to limit what files it can read, prompts are passed as arguments rather than through a shell to avoid command injection, and assistant replies are sanitized before being displayed.
