Show HN: Dev Toolbox – A browser extension with simple offline dev tools

4 points by cnanney 4 years ago · 0 comments · 1 min read

Hello HN!

I'd like to share a browser extension I made that provides quick offline access to various development tools.

Current tool set: Calculate hashes; encode and decode HTML, URI, Base64; convert numbers between different bases; parse and manipulate various time formats; format and inspect IPv4/CIDR addresses; search all v13.1 emoji with quick copying in various formats.

It runs entirely offline, making no external requests (even emoji PNG files are bundled), and only requires local storage permission to remember your last tab and input.

This was inspired by an old extension called Hasher (no longer on the Chrome Store) that provided a simple interface to similar utilities. This was an opportunity to get back into making extensions, practice with Vue a bit, and expand upon the original idea.

It's available for Chrome, Edge (via Chrome Store), and Firefox; links and screenshots are on GitHub, where you can also report any problems. Feedback and suggestions are very welcome. Thanks!
