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:

https://catssaymeow.org

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.
