Hey Product Hunt! 👋 I'm building TechTools365 because I got frustrated with existing tools: - Every financial calculator is either buried under ads or uses wrong formulas - Visa checkers only handle one passport (millions of people hold multiple) - SaaS comparison sites have sponsored rankings disguised as reviews So I built what I actually needed: 1. CalcStack — calculators that let you play with scenarios, compare options, and see the math. Not just "enter number, get answer." The Old vs New Tax Regime Comparator shows both regimes side-by-side with your actual deductions. The FIRE Calculator is adjusted for Indian conditions (6-7% inflation, not US 2%). 2. VisaPathway — I'm an Indian living in UAE. A UAE residence permit unlocks extra countries, a US visa unlocks more. No tool checked all my documents together. So I built one that does. 3. ToolVersus — I was comparing VPNs and every "review" site was clearly paid by NordVPN. I built comparisons with real pricing data and honest verdicts. Everything is free, runs in browser, zero data collection. Built with Astro, Hugo, Preact, hosted on Cloudflare Pages (free tier). Would love your feedback — what tools should I add next?
