About MyDevKit

MyDevKit is a collection of in-browser utilities for everyday dev tasks: format JSON, YAML, XML, HTML, CSS, and Markdown; encode and decode Base64, URLs, and JWTs; generate UUIDs, passwords, hashes, and placeholder text; convert timestamps, timezones, and data formats like CSV and JSON; preview HTML, SVG, and Markdown. Everything runs in your browser so your data never leaves your device.

Built to be simple and always available—tidy a payload, decode a token, or grab a UUID without leaving the tab or creating an account.

Who publishes MyDevKit

MyDevKit is independently published and maintained as a browser-first developer utility site. The goal is straightforward: offer practical tools and implementation guides that are fast to open, easy to trust, and useful during real debugging or build workflows.

Who it's for

Backend developers debugging API responses, frontend engineers preparing mock data, DevOps folks converting config formats, and anyone who needs a quick format, encode, or convert without firing up a terminal or installing another package. MyDevKit works on any device with a browser—no setup, no signup, no limits.

How it works

Paste, upload, or type your input. The tool processes it locally in JavaScript—nothing is sent to a server. Results appear instantly. You can copy, download, or keep iterating. All processing happens in your browser tab, so your data stays private and the tools work offline once the page has loaded.

How the site is maintained

We review tools for accuracy, keep the privacy model local-first wherever possible, and publish practical guides that explain when a tool should be used, what it does, and what its limitations are. When a tool has tradeoffs, the goal is to document those clearly rather than hide them behind marketing copy.
