What this site is
mybittools.com is a collection of single purpose web tools for programmers and anyone who works with data. Each tool does one job well, loads in under a second, and asks nothing of you. There is no account to create, no email to hand over and no paywall.
The site started with a single UUID generator built for my own use. I kept needing one during work and every option I found was slow, cluttered with popups, or wanted me to sign up. So I built a clean one and put it online. The JSON formatter followed for the same reason. More tools are on the way.
How the tools work
Every tool on this site runs completely inside your browser using JavaScript. When you generate a UUID or format a JSON document, the work happens on your own machine. Nothing you type is sent to our servers, logged, or stored. You can confirm this yourself by opening the network tab in your browser's developer tools.
This design choice matters for two reasons:
- Privacy: you can safely paste config files, API responses or anything else sensitive. It never leaves your computer.
- Speed: there is no round trip to a server, so results appear instantly even on a slow connection.
Current tools
- UUID Generator: generate up to 50 UUIDs at once in version 1, 4 or 7, with one click copy for each value or the whole list.
- JSON Formatter and Validator: pretty print, minify, sort keys and find syntax errors with exact line and column numbers.
Each tool page also includes a short guide explaining the underlying concept, so the site is useful even if you just want to learn what a UUID v7 is.
Who builds it
The site is built and maintained by Sheng Pang, a software developer. It is a side project, not a company. The source is a simple static site built with Vite and served by Nginx, and the code is written by hand with no heavy frameworks so that pages stay small.
How the site is funded
Hosting and the domain cost money, so the site shows a small number of ads through Google AdSense. Ads are the only source of income and the only reason any third party script is loaded. You can read exactly what data those services collect in our Privacy Policy.
