Show HN: I made a fast, offline-first developer toolkit with no ads or tracking

Hey HN,

I was fed up with using online converters and generators. They were slow. They used server encoding. They were full of ads. Or they required cookie confirmation for simple tasks.

Opening VS Code or Sublime with plugins was also slow.

So, I built a simple, web-based toolkit called Stringify that I thought some of you might find useful. It started as a personal project with no aspirations to make money from it. I remember a time when people used to create online projects and websites just for fun :)

It’s a single index.html file with vanilla JavaScript that handles common developer tasks such as:

URL, Base64 and JSON encoding and decoding. JSON formatting and minification; MD5 and SHA-1 hashing, UUIDv4 and Nano ID generation. It also contains a JavaScript object-to-JSON converter for handling unquoted keys and similar issues.

Everything is processed on the client side, so it’s completely private and can be used offline. There are no ads, trackers or cookies, and no server-side processing. It’s just a fast, functional tool inspired by the minimalist tools I admire.

I'd love to hear your feedback or suggestions for other useful features to add.

You maybe can rewrite it in Python and make the code the CudaText and/or Sublime Text python plugin. Several of your commands exist as cudatext plugins already: base64, url encoders. JSON formatter exists too in CudaFormatter plugin.
