I built a collection of 65+ browser-based developer tools

Been working on this side project for a while and figured Showoff Saturday was a good time to share it.

It's called Toolpod, a collection of developer tools that run entirely in the browser. JSON formatter, Base64 encoder, JWT decoder, regex tester, UUID generator, that kind of stuff. Nothing gets sent to a server, everything runs client-side.

I built it because I got tired of googling "json formatter online" every time I needed to prettify some API response, only to land on some ad-covered site that may or may not be logging my data.

The whole thing is static, hosted on Firebase, costs me about $20/month to run. Built with Next.js and Tailwind.

Some tools I use the most myself:

* JSON formatter

* JWT decoder for debugging auth issues

* YAML to JSON converter for dealing with config files

* Regex tester when I inevitably forget how capture groups work

Also added a few other sections:

**API Directory** with 100+ public APIs organized by category. Handy when you need a free API for a side project and don't want to dig through outdated lists.

**Dev Blog** with articles on stuff like JWT security, JSON validation, regex basics. Trying to write things I wish I had when I was learning this stuff.

Would love any feedback on what tools might be missing or what could be improved.

One last thing, the site was well guided with a combination of Claude and Cursor. It Was quite effective using Claude to help build the instructions for Cursor to digest and build.
