Simple dev utilities that run entirely in your browser: https://brequet.github.io/dev-tools/

At work, I constantly need to format JSON or XML, compare text snippets, or do quick date calculations. I do not trust most online tools that they do not send your data to their servers, which wouldn’t be ideal when dealing with sensitive information. I built this collection to have these utilities always available in my browser, with everything running locally. Also, I like to build my own tools!

Tools included

  • Formatter/Minifier - Format or minify JSON and XML with automatic language detection
  • Diff Viewer - Compare text or code side-by-side with optional auto-formatting for JSON/XML
  • Date Finder - Find specific dates from day of the year
  • Lorem Ipsum Generator - Generate placeholder text by word, phrase, or paragraph
  • Probably more to come if I ever need them

Privacy

Everything runs in your browser. No data is sent to any server - what you paste stays on your machine.
