I Just Launched NoCostTools.com — A Free Tools Hub for Finance & Daily Utilities (Feedback Appreciated!)

Hi Dev Community!
I’ve been working on a project that I finally feel confident sharing publicly — NoCostTools.com, a platform offering completely free calculators and utilities, with a focus on finance and productivity.

🔧 Why I Built This

Most “free tools” websites hide features behind ads or pop-ups. I wanted something:

✔️ Fast
✔️ Ad-light
✔️ Accurate
✔️ Easy for everyone to use
✔️ Dev-friendly (every tool built modular + scalable)

🧰 What’s Live Right Now

SIP Calculator (React + WordPress hybrid)

SWP, Lumpsum, CAGR, EMI and more (rolling out weekly)

Performance-optimized using:

Lightweight JS

Server-level caching

SEO-structured schema

Clean UI

🎯 Tech Stack & Decisions

Frontend: React (for tools UI)

Backend: WordPress (Headless-like setup)

Custom plugin system to inject React apps

All tools are built component-first for reusability
