I built 49 free online tools in 3 months — here's what I learned
I have a confession. Every time I needed to calculate my EMI, check my BMI, or figure out how many college classes I could skip — I'd Google it, land on some site plastered with ads, get asked to sign up, and then give up halfway. So I did what any frustrated developer does. I built my own. How It Started It started with one EMI calculator. Just a simple HTML page I made for myself to calculate…
A developer fed up with ad-filled, signup-required financial and health calculators decided to create his own free online tools. Starting with a single EMI calculator page, the project grew to include 49 tools across five categories: finance, health, freelance, student, and utility. The developer's three non-negotiable rules were no signups, no ads, and mobile compatibility.
Built using only HTML, CSS, and JavaScript, the site runs on GitHub Pages for free hosting and is optimized for speed and search engine optimization. The first tool, a student attendance tracker, quickly became the most popular. With early user feedback and community input in mind, the developer plans to add more tools, improve mobile experience, and include a shareable results feature where users can easily share their calculations.
