Hey everyone 👋
I’ve been working on a small passion project called Tools25
— a set of 6 free online developer tools that run completely in your browser.

🧰 What’s inside

JSON Formatter & Validator

Secure Password Generator

Base64 Encoder/Decoder

Hash Generator (MD5, SHA256, SHA512)

URL Encoder/Decoder

Lorem Ipsum Generator

All the tools are 100% browser-based — no tracking, no login, no backend data storage. I built them because I was tired of using ad-heavy or slow “free tool” websites.

⚙️ How I built it

Everything runs on a lightweight WordPress + custom plugin setup.
Each tool is written in vanilla JavaScript for speed and simplicity.

I focused on:

Keeping the UI clean and responsive (TailwindCSS + Elementor).

Fast load times (no external APIs).

SEO and accessibility from day one.

💡 What I learned

Simple solves problems. People want quick, distraction-free utilities.

Performance > fancy design. Fast pages beat animations every time.

Launch early, improve fast. I shipped the MVP, then improved it after user feedback on Product Hunt.

Privacy is appreciated. Users love tools that don’t send data anywhere.

🚀 Try it yourself

Thanks for reading — hope this inspires you to build something small and useful too.
