Daily coding challenges to keep developer skills sharp with AI assistance and streak tracking.

No signup required to try it: https://unrot.dev

One-person shop, building this as a second income around a day job, so feedback from this crowd is gold. What it is: every career tool hands you a confident AI recommendation. I wanted the opposite — something that reads live job postings, measures how much of a target role your current skills already cover, and shows the honest version: the salar

I've been slowly adding some new free tools to Moxie Docs (partly for SEO, partly to illustrate some of our feature sets before any commitment) for some reason this mermaid editor one blew up on Google rankings so I figured I'd share in case people find it useful!
