Standalone HTML files are a good approach
From 1 comment
I do like the standalone HTML file approach. With coding agents it's quite easy to build a suite of tools for personal use. Additionally if you review the code, you can trust if…

Objections
Hosted on GitHub Pages and CDNs undermine the privacy claim
From 4 comments
Nice, however: > Vanilla JavaScript (ES6+) CSS3 with CSS Grid Minimal external libraries: marked.js, exifr, highlight.js, sql-formatter (all from CDN) No frameworks, no bundlers,…

Hard to remember the site name when needed
From 2 comments
- my gripe with most of these tools is that whenever i actually need one, i can never seem to remember their name. - That kills like half the traffic for you guys. - For example…
vivzkestrel on HNI like initiatives like this but the issue I have mostly is that whenever I have a specific need, say, I need to format a piece of JSON, I would directly google "json formatter"…

Resizable input and output fields

Would there be a way to resize the input/output fields? Current layout only accepts 3 lines which is not sufficient when formatting SQL or JSON.

VS Code extension or desktop/TUI version
From 2 comments
What would make this really useful to me it's having it in Vscode as an extension. I'm sure lots of the tools are already available but a visual panel would help to remember them.
esperent on HNThis would be a great tool if it was a local tool that could run in a tui or as a desktop app ala devtoys on Windows

DevToys

This looks great and will definitely check out! I've been using DevToys on my local machine for years but a recent update made it almost unusable.
