  Hi HN, I’ve been working on a small tool called [PrettyPost](https://www.prettypost.io/) that takes social media posts—or even your own uploaded screenshots—and turns them into clean, visually pleasing images you can share anywhere. The motivation came from frustration with messy manual screenshots: cropping out UI clutter, engagement counts, or random background distractions. With PrettyPost, you just drop in a link (or upload a screenshot), and it generates a polished, minimal graphic you can use for newsletters, blogs, LinkedIn, Instagram, or just to archive your own…

  Tetris in a PDF▲1,289

  I realized that the PDF engines of modern desktop browsers (PDFium and PDF.js) support JavaScript with enough I/O primitives to make a basic game like Tetris. It was a bit tricky to find a union of features that work in both engines, but in the end it turns out that showing/hiding annotation "fields" works well to make monochrome pixels, and keyboard input can be achieved by typing in a text input box. All in all it's quite janky but a nice reminder of how general purpose PDF scripting can be. The linked PDF is all ASCII so you can just open it in a text editor, or have a look at…

  21st.dev▲1,211

  I originally built this app to organize and reuse interesting React + Tailwind components I came across on Twitter, inspired by the shadcn/ui approach.

Would love to hear your thoughts!
