DEV Community: CatsSayMEOW

A website to save you from messy browser tabs

I saw some posts where people complained about having too many tabs open and constantly switching between basic tools like JWT decoder, Base64 encoder/decoder, data generators, API client, editor, and so on.

I can relate, because that’s exactly what I was dealing with a few months ago. So I started building an all-in-one toolkit for my daily work:

It has a cyber-noir + cat theme, with dark mode by default.
There are 9 tools in total, but two I think are worth calling out:

JSON Formatter: supports custom nested levels and a visualizer
Markdown Editor: GitHub-like features, plus a bit more

I also optimized it to work better on mobile. Yes! I really did have to debug a JSON payload while traveling at night on my tiny iPhone, so mobile support became personal.

Hope you find it useful. If not, that’s fine. My cat-themed nonsense will continue existing either way.

Are non-AI dev tools becoming irrelevant?

I’m a software engineer, and a big part of my day is debugging issues reported by other teams.

Most of the time I’m:

checking tokens
calling APIs
comparing JSON responses and traces
writing docs

I kept jumping between different tools for all of this, and it always felt clunky.

I tried finding a lightweight toolkit with a clean UI and smooth workflow, but most tools either felt outdated or started adding AI features that didn’t really make sense to me — especially for workflows involving sensitive tokens or internal data.

So I ended up building a small toolkit for myself: https://qautils.catssaymeow.org/

What surprised me was that when I showed it to teammates, some of them immediately asked:

“Why doesn’t it have AI support?”

Personally, I don’t really see the need for AI in tools like JSON formatting, token inspection, API calls, etc.

Do simple dev tools actually benefit from AI, or are we just expecting AI everywhere now?
