About Dev Tools Hub

A collection of free, fast, and privacy-first developer tools — built by developers, for developers.

What is Dev Tools Hub?

Dev Tools Hub is a free online collection of developer utilities designed to make everyday technical tasks faster and easier. Every tool on this site runs entirely in your browser — no server calls, no data collection, no accounts required.

Whether you need to format a JSON response, decode a JWT token, generate UUIDs, convert timestamps, or test a regular expression, you can do it instantly without pasting your data into an unknown server.

Our Principles

  • Privacy by default: Your data never leaves your browser. We do not log, store, or transmit anything you input into our tools.
  • Always free: Core tools will always be available for free. No paywalls, no trials, no credit card.
  • Fast and lightweight: No heavy frameworks, no bloat. Tools load quickly and respond instantly.
  • Built for real developers: We build tools we use ourselves. No filler, no fluff — just practical utilities.
