Hey Product Hunt community! 👋 I'm Sashank, the maker of TWShift. As a developer who loves Tailwind CSS, I was excited about v4 but knew the manual config migration would be a pain point for many. That's why I built TWShift! My goal was to create a simple, fast, and intelligent tool that leverages AI to: ✅ Accurately convert v3 `tailwind.config.js` to the new v4 CSS-first syntax. ✅ Handle complex parts like `theme` customizations (colors, spacing, breakpoints including rem conversion!), `keyframes`, `animations`, and even attempt to translate custom plugins. ✅ Provide helpful warnings and info comments for parts that might need a manual touch. Tailwind v4 brings amazing performance improvements and a more intuitive CSS-first approach, and TWShift is here to help you adopt it without the usual migration headaches. 🔗 Give it a try at: https://twshift.com/ I'd absolutely love to hear your feedback! What do you think? What other features would make your Tailwind workflow even smoother? Thanks for checking out TWShift! 🙏 Sashank
