Overview
What is LucenaCoder?
LucenaCoder is a free, local, token-efficiency obsessed coding harness produced by Lucena.One, an applied AI research lab focused on extreme token-efficiency and deterministic outcomes. The primary way to use it is the desktop app, available for macOS, Windows, and Linux: client-side by default, no login, and your keys, chats, and code stay on your machine. Bring an OpenRouter key or any custom OpenAI-compatible endpoint. If you'd rather not install, you can also run npx lucenacoder to launch a workspace in-browser from any folder on your machine, and Browser Lite lives at https://lucenacoder.com/browser. The company site and blog are at https://lucena.one/. For long-running, hands-off work, try Underboss autonomous (Pro Beta).
