Why this exists

Story

I built vessel.nunchi because I needed it—and I figured other people probably do too. I was vibe-coding with "gemini 1.5" and then… it got shut down (for me) way sooner than I expected. No heads-up. No timeline. Just gone.

Stuff like this happens a lot with vibe coding. AI writes code based on what it learned at training time, but the real world changes every week—APIs move, packages deprecate, services disappear. I just wanted a simple place to see what’s changing, and get a heads-up when something turns into a problem.
