About Pro Utility Center

A growing collection of fast, free online tools built with vanilla JavaScript — no frameworks, no sign-ups, no nonsense.

🚀 What This Is

Pro Utility Center is a side project turned utility toolbox. It started as a way to scratch a specific itch — having fast, reliable, privacy-respecting tools always a tab away — and grew into a collection of 18+ utilities covering networking, developer tasks, text manipulation, and everyday calculations.

Every tool runs entirely in your browser. No data is sent to a server, no logs are kept, and nothing is stored beyond your session. Your IP lookup hits a public API, DNS queries go through Google DNS over HTTPS, and everything else stays client-side.

💡 Why Use It

  • Zero sign-up or tracking
  • Works offline after first load (for client-side tools)
  • Dark mode support
  • Keyboard accessible
  • No bloat — loads fast even on slow connections
  • Tools work without JavaScript frameworks

🔧 Tech Stack

Built with the basics, on purpose. No build step, no bundler, no npm dependencies at runtime.
