Is this the perfect 404 page? [CSS only]
GitHub repo: https://github.com/AntiKippi/errorpages Live preview: https://kippi.at/public/errorpages/ I've spend the last few days overengineering HTTP status code error pages. It started with me wanting an aesthetic, glitchy 404 page with a bit of "cyberpunk" and "hacker" vibes while still being simple and JS free. It ended in this project. wdyt?

http://instacss.com (in case DNS update hasn't propagated: http://morning-warrior-3377.herokuapp.com/) Last night I was annoyed at how slow (and web 1.0-ish) most CSS reference sites seem to be, so I created this. It's basically a scrape of the CSS reference on w3schools, but with client side searching. Feedback is most welcome! some of the tech involved: node, requirejs, backbone, mongodb the code: http://github.com/rgarcia/instacss

URL: http://reallygood404.com/ I wanted to put together a showcase of some great 404 pages since there seem to be a lot of hidden gems. Would love feedback and other 404 pages that I haven't seen/found yet if people are willing to share.

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
