No sign-ups. Just clean, fast tools.</p> <h2> Some popular ones: </h2> <ul> <li><strong>Compound Interest Calculator</strong></li> <li><strong>BMI Calculator</strong></li> <li><strong>Mortgage Payment Calculator</strong></li> <li><strong>Scientific Calculator</strong></li> </ul> <h2> Tech Stack </h2> <p>Built with Astro (SSR). Fast, SEO-optimized, and fully static where possible.</p> <h2> Why I built it </h2> <p>Most calculator sites are cluttered with ads or lock results behind email sign-ups. I wanted something clean and instant.</p> <p>Check it out: <a href="https://novacalculator.com" rel="noopener noreferrer">novacalculator.com</a></p> <p>Happy to answer any questions about the tech stack or how I handled 5,500+ pages!</p> webdev productivity javascript
