Putting a screenshot into a device mockup still means opening a PSD, hunting for the Smart Object and re-exporting it by hand. MochiMockup does it in the browser in about 30 seconds: your design is warped onto the device with a homography, so it follows the real angle of the screen instead of sitting flat on top of it. 545 templates across iPhone, MacBook, iPad and Apple Watch. Exports up to 4K, runs as a Figma plugin too, and the free templates export without an account.
