OpenToolBox
The privacy-first, all-in-one toolbox that runs in browser
What it does
OpenToolBox is a free, privacy-focused suite of developer tools where every operation happens 100% client-side in your browser. Your code, documents, and data never leave your computer. Why This Matters: As developers, we constantly upload sensitive data to random websites contracts to PDF signers, proprietary code to JSON validators, personal documents to image converters. OpenToolBox eliminates this risk by processing everything locally.

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
