Loupe

AI builds it. You perfect it. Live, and verified.·tryloupe.app

Loupe is an open-source, local Windows AI website builder and web-design studio. AI agents build real websites, and every AI edit is automatically verified against the real render before the user finishes the rest by hand — selecting, moving, resizing, and editing — on the same live page. Users bring their own API keys or existing AI subscriptions (Claude, ChatGPT, Grok, Copilot, etc.) to power the build engines. It is MIT-licensed and runs entirely locally on Windows.
