Hi Product Hunt! 👋 I built DevKit because I was tired of opening 10+ browser tabs for basic dev tasks — Base64 encoding, JSON formatting, UUID generation, regex testing... So I put 26 of the most common developer tools into one app. Everything runs 100% client-side — no backend, no accounts, your data never leaves your browser. Some highlights: - JWT Decoder — paste a token, instantly see the payload - Cron Explainer — finally understand what 0 */6 * * 1-5 means - CSS Gradient Generator — visual builder with one-click copy - Password Generator — customizable, secure, bulk generation Built with React + TypeScript + Tailwind CSS, hosted on Cloudflare Pages. Would love to hear what tools you'd add next! 🚀
