Show HN: I vibecoded 177 tools for my own use (CalcBin) Hey HN! I've been building random tools whenever I needed them over the past few months, and now I have 177 of them. Started because I was tired of sketchy converter sites with 10 ads, so I just... made my own. Some highlights for the dev crowd: Developer tools: - UUID Generator (v1/v4/v7, bulk generation): https://ift.tt/wSF64ZI - JWT Generator & Decoder: https://ift.tt/GwZRLV5 - JSON Formatter/Validator: https://ift.tt/rlResUb - Cron Expression Generator (with natural language): https://ift.tt/7dbBqN4 - Base64 Encoder/Decoder: https://ift.tt/uyYbPnc - Regex Tester: https://ift.tt/PvGeSQ1 - SVG Optimizer (SVGO-powered, client-side): https://ift.tt/2xTRKXW Fun ones: - Random Name Picker (spin wheel animation): https://ift.tt/QjRWtZv - QR Code Generator: https://ift.tt/XP7JNBW Everything runs client-side (Next.js + React), no ads, no tracking, works offline. Built it for myself but figured others might find it useful. Browse all tools: https://ift.tt/zbNWiFq Tech: Next.js 14 App Router, TypeScript, Tailwind, Turborepo monorepo. All open to feedback! https://calcbin.com February 10, 2026 at 11:46PM
