WHY IT'S INTERESTING

177 tools, from kg-to-lbs to Unix timestamps
Unit conversions, Base64 encoding, JSON↔CSV, color format switching — the range is wide. The keyword is vibecoded: the author openly says AI helped build these. 177 isn't artisanal craft — it's an experiment in how far one person can stretch a toolbox with AI assistance
