As developers, we often need small utilities while coding — formatting JSON, decoding JWT tokens, formatting CSS, or quickly checking data structures.
Most of the time we open a random online tool, paste our data, and hope it doesn’t store or track it.
So I decided to build something simple and privacy-friendly.
Introducing ByteKit
I built ByteKit, a collection of 12 free developer tools that run entirely in the browser.
The goal was simple:
No login required
No tracking
No data sent to servers
Everything runs client-side
This means your data never leaves your browser.
Tools Currently Available
ByteKit currently includes tools like:
JSON Formatter & Validator
CSS Formatter
JWT Decoder
Base64 Encoder / Decoder
URL Encoder / Decoder
HTML Formatter
Text Utilities
and more...
These are the kinds of tools developers repeatedly search for during daily development.
Why I Built It
I wanted a single lightweight place where developers could quickly access common utilities without ads, signups, or privacy concerns.
Many existing tools:
Require login
Track usage
Or send data to servers
ByteKit avoids all of that by processing everything directly in the browser using JavaScript.
Tech Behind It
The project is intentionally simple:
Vanilla JavaScript
Client-side processing
Fast and lightweight
No backend required
This keeps the tools fast and ensures privacy.
Try It Out
If you're a developer who often needs quick formatting or encoding tools, feel free to check it out:
Feedback and suggestions are welcome — I’m planning to add more tools soon.
