  Prism.Tools – Free and privacy-focused developer utilitiesJan 2026 · blgardner.github.io · ▲380

  Hi HN, I'm Barry and I've built Prism.Tools (https://blgardner.github.io/prism.tools/) – a collection of client-side developer utilities that respect your privacy.

As I locate more tools others may find useful I will refine and add them to the collection. Use them, Share them, or not.…

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