Show HN: String Flux – Simplify everyday string transformations for developers

I built https://stringflux.io/ to make everyday string transformations a little less painful. It’s similar to CyberChef in the sense that it supports multiple string operations, but with a cleaner, more focused UI and smart suggestions based on your input.

You can also chain transformations — for example: decode base64 string which was base64 encoded from minified json → then json format (pretty-print) it — all in one flow. This is helpful when dealing with complex or nested strings, like encoded API responses or log data, where you need to apply multiple steps to make the content readable.

The idea came from the frustration of jumping between different tools just to handle common string tasks.

There’s a short GIF demo in the GitHub README: https://github.com/stringflux/stringflux

Would love to hear your thoughts and feedback!

I didn't find code in the github for a self hosting option. From security standpoint it is not a good idea to paste Strings in someone's website & share sensitive/protected data. Self hosting would be a good option.

Wow, this is one step away from a free online password quality verifier!

I thought this would be a useful library and I was curious what platforms it supported.
