# Duo Studio — foldable phone mockups

Duo Studio is an open-source, browser-based tool for creating foldable phone mockups and folding animations from app screenshots. Upload inner and outer screen images, choose a device pose, and export a visual for your product launch. Browser simulation previews websites that permit iframe embedding. The editor processes screenshots locally and runs on static hosting. Duo Studio creates iPhone Duo-style visual mockups; it does not run iOS and is not an Apple product.
