🚀 I built 100+ developer tools that run entirely in your browser
Over the past few months, I’ve been working on a simple idea:
👉 What if developers could use powerful tools instantly — without login, without backend, and without sending data anywhere?
So I built TonuDevTool.
🔧 What is TonuDevTool?
TonuDevTool is a collection of 200+ free developer tools that run directly in your browser.
No installs. No API calls. No tracking.
Just open and use.
⚡ Why I built this
As a developer, I got tired of:
- Tools that require login
- Slow tools with server processing
- Privacy concerns (sending sensitive data to servers)
- Ads and distractions everywhere
So I decided to build something:
- ⚡ Fast
- 🔒 Private
- 🧑💻 Developer-friendly
🧰 What kind of tools are included?
Here are some examples:
- JSON Formatter & Validator
- CSS Minifier & Generators
- Base64 Encoder / Decoder
- Regex Tester
- Timestamp Converter
- UUID Generator
- API & HTTP Tools
- Text & SEO Tools
And many more…
🔥 Key Features
- ⚡ Lightning fast — runs in your browser
- 🔒 100% private — no data leaves your device
- 🚫 No login required
- 🧑💻 Built for developers
🧠 How it works
Everything is built using modern frontend technologies.
No backend. No database.
This means:
- Zero cost to run
- Infinite scalability
- Instant performance
