Show HN: I built 17 free dev tools that work offline in the browser

1 abhaysinghr516 0 9/14/2025, 2:24:04 PM businesswish.tech ↗

Hey everyone, I just added a major update to my open-source project: a suite of 17 tools that run entirely in your browser with zero tracking. I wanted a set of utilities (like a color contrast checker, JSON formatter, image compressor, etc.) where I wouldn't have to worry about my data being sent to a server.

A few of the tools included: WCAG Contrast Checker & Blindness Simulator CSS Flexbox, Grid, and Gradient Generators Image Compressor & Formatter JSON Formatter & CSV to JSON converter QR Code Generator

Everything is 100% local and works offline. Hope you find it useful! Feedback and ideas for new tools are very welcome.
