PatchWatch

What it does

PatchWatch helps security and IT teams stay on top of critical security patches without drowning in alerts. Instead of checking multiple sources manually, PatchWatch aggregates security advisories from Microsoft MSRC, NVD, and OSV into one clean dashboard. Built for patch engineers, security teams, MSPs, and IT admins who want clarity, not noise. PatchWatch is currently in early access & feedback from real practitioners is highly welcome.

  isometric.nyc – giant isometric pixel art map of NYC▲1,325

  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
