About DevTools Hub

DevTools Hub is a collection of free, fast, and privacy-focused online tools built for developers, designers, and anyone who works with data on the web.

Our Mission

We believe essential developer tools should be free, fast, and respect your privacy. Too many online tools are bloated with ads, require sign-ups, or send your data to remote servers. DevTools Hub takes a different approach: every tool runs entirely in your browser. Your data never leaves your device.

What We Offer

DevTools Hub provides over 100 tools across several categories:

  • Developer Tools — JSON formatter, regex tester, diff checker, SQL formatter, cron builder, and more.
  • Text Utilities — Word counter, case converter, slug generator, Lorem Ipsum generator, and text comparison tools.
  • Converters & Encoders — Base64 encoder, URL encoder, CSV to JSON, Markdown to HTML, and format converters for everyday workflows.
  • Calculators — Compound interest, BMI, tip calculator, concrete calculator, and specialised tools for Australian tax and super.
  • Design & CSS — Color picker, gradient generator, box shadow builder, glassmorphism generator, and more visual tools.
  • AI-Powered Tools — Regex generator, email writer, commit message generator, and meta description writer powered by Claude AI.

Privacy First

Privacy is not a feature — it is a core design principle. The vast majority of our tools process data entirely in your browser using client-side JavaScript. No data is sent to any server, stored in any database, or shared with any third party. The only exceptions are our AI-powered tools, which send your input to an AI model to generate a response — and even then, we do not store your data.

Built With Modern Technology

DevTools Hub is built with Next.js, React, and Tailwind CSS. We use server-side rendering and static generation for fast page loads, semantic HTML for accessibility, and structured data (JSON-LD) for rich search engine results. The entire site is open, fast, and designed to get out of your way so you can focus on what matters: building great software.
