About MyDevSuite

A collection of free, fast developer utilities that respect your time and your privacy. No accounts. No paywalls. No data leaving your device.

Why it exists

Most online developer tools are slow, ad-heavy, or quietly send your data to a server. You paste a JWT token into a random website and wonder where it went. You format some JSON and hope the company behind the site isn't logging it.

MyDevSuite is the answer to that. Every tool runs entirely in your browser — the server only delivers the HTML, CSS, and JS. After that, it's all local.

Principles

lock

Private by default

Your input never leaves your browser. No logging, no analytics on tool usage, no data storage.

Plain HTML + CSS + JS. No framework overhead. No build step. Pages load in milliseconds.
