About DevKit
DevKit is a free collection of small developer utilities — formatters, encoders, comparators and inspectors — that run entirely inside your browser. It is built and maintained by Hitesh Singla.
Why the tools run in your browser
Most online developer tools send whatever you paste into them to a server. That is a real risk when the thing you are pasting is a config file, an access token, or a customer record. Every tool here does its work in JavaScript on your own machine, so the contents of an editor never leave the browser tab. The privacy page describes this in detail.
What is here
Seventeen tools across text editing, formatting, encoding, comparison and reference data. The full list is one click away; each tool page explains what it does, how to use it, and answers the questions people actually ask about it.
Reporting a problem
If a tool gives a wrong answer, mangles your input, or simply breaks on a particular browser, that is a bug worth hearing about. The fastest route is the contact page.
