ShotStudio

ShotStudio is a free, browser-based tool for turning plain screenshots into beautiful 3D mockups. It positions itself around speed, presenting itself as a way to create polished 3D screenshot mockups instantly without design software. It is aimed at makers, developers, and marketers who want to dress up screenshots for social posts, landing pages, documentation, or launch material. The tool fits into the same category as browser-based screenshot beautifiers that add gradient backgrounds, device or window framing, 3D perspective transforms, and annotations on top of an uploaded image, producing a ready-to-share graphic in a few clicks rather than in a full editor like Photoshop. It is offered free of charge and runs in the browser.
