I'm Parimal, a solo developer, and I built Tooltri because I was tired of opening five different sites (and closing five popup ads) just to format some JSON or calculate an EMI. Everything on Tooltri runs entirely in your browser - no sign-up, no server-side processing, no data logging. Your financial figures, passwords, and code never leave your device. Right now it includes: - Developer tools: JSON formatter, JWT decoder, UUID generator, hash generator, Base64/URL encoders, token counter, and more - Financial tools: SIP, EMI, ROI, SWP calculators, and an India income tax calculator (New vs Old regime comparison) I built the entire stack myself - Next.js frontend, Laravel backend (for the contact form) - and I'm actively adding new tools based on feedback. Would love to hear which tool you find most useful, and what you'd want added next!!!
