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://calcbin.com/tools/uuid-generator - JWT Generator & Decoder: https://calcbin.com/tools/jwt-generator - JSON Formatter/Validator: https://calcbin.com/tools/json-formatter - Cron Expression Generator (with…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years.
