What Loupe is
Loupe is a free, open-source desktop AI website builder and web-design studio. It creates local websites from prompts, then lets you edit the rendered page directly. The editor supports selecting, moving, resizing, rotating, aligning and arranging elements with auto-layout, plus changing text and styles. Loupe compares the page before and after each AI edit with a pixel difference check. Build modes include Solo and Studio, with experimental Swarm and autonomous Loop modes. A bundled design library contains about 1,300 references. Listed AI connections include Claude, OpenRouter, OpenAI, Gemini, xAI, Codex, Grok, Copilot and MiMo. Image tools cover checked stock, generated images and CC0 3D HDRIs from Poly Haven. Full code export is available, but hosting is not included. Provider keys stay local and are sent only to the chosen service. Windows 10/11 64-bit is tested; macOS and Linux require building from source.
