270+ developer tools built with Next.js — your browser-based dev toolkit
Designed and built an all-in-one browser-based developer toolkit with 270+ tools: JSON formatter, Base64 encoder, diff viewer, regex tester, color converter, UUID generator, and more. Zero backend — runs entirely in the browser.
Delivering 270+ tools with a sub-100ms LCP across all routes.
Aggressive code splitting by tool category, dynamic imports for heavy parsers, and Tailwind v4 for zero-runtime CSS.
