Moocup
Drop your screenshot, a base style is applied, style it however you wish, and export - "that's basically it," says Moocup's own author, and the description holds. The workflow is genuinely seconds long. Drag an image in and it lands on an attractive backdrop immediately; from there you adjust backgrounds, gradients, padding, borders, shadows, and framing with live preview until it matches your taste, then export a high-quality image ready for a portfolio page, README, blog post, tweet, or slide deck. There are no accounts, no watermarks, and no upload to anyone's cloud - as a self-hosted static app, your screenshots never leave your infrastructure, which matters when the screenshot shows a proprietary dashboard or unreleased product. It runs entirely in the browser from a tiny nginx container, works on any device, and requires zero design skill: the smart defaults do the heavy lifting, and everything else is optional tinkering.
