About

This site is a small workshop of everyday developer tools: formatters, validators, converters, encoders, minifiers and a regular expression tester. Each tool does one job, does it on your own machine, and gets out of the way.

The workshop opened with twenty tools and grows in phases, adding the most-requested jobs first. Every tool is tested against known inputs and outputs before it is published, and each page explains plainly what the tool does — including, where it matters, what it does not do.

There are no accounts, no uploads and no usage limits. The tools are plain JavaScript; the page you are reading is the whole machine.
