The idea
So I decided to build something simple:
A single platform with all the tools I need — in one place.
That’s how TonuDevTool was born.
What it offers
TonuDevTool is a collection of 200+ free developer tools that run entirely in the browser.
- No installs.
- No login.
- No tracking.
Some of the tools include:
- JSON Formatter & Validator
- CSS Minifier & Beautifier
- HTML Formatter
- Base64 Encoder/Decoder
- UI Generators (Glassmorphism, Neumorphism, etc.)
- And many more…
Key features
- Instant results
- 100 % private (no server processing)
- Fast and lightweight
- Works directly in your browser
Why I built it
My goal was simple: save time and make developers more productive. Instead of jumping between ten different websites, everything is now in one place.
Launching on Product Hunt
I recently launched TonuDevTool on Product Hunt. If you find it useful, I’d really appreciate your support and feedback.
