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…
In plain words
String Flux is a web-based tool for developers that performs multiple string transformations, such as base64 decoding, JSON formatting, and minification reversal. It offers a cleaner interface than similar tools and provides smart suggestions based on input. Users can chain multiple transformations together in a single workflow, making it useful for processing encoded API responses and log data. The tool was built to eliminate the need to switch between different utilities for common string manipulation tasks.

In the maker’s words, at launch
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!

Hey HN! Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on. Since I track everything digitally (some people still just use paper logbooks!), I put together some data visualizations and a few 3D globes to show my flying history. This globe is probably my favourite so far: https://jameshard.ing/pilot/globes/all If you’ve got ideas for other graphs or ways to show this kind of data, I’d love to hear them!

I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine. The project had traction (1.4k GitHub stars, 95 forks, ~20K visits/month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say. I couldn't just let it die So I built the new version from scratch with the same open-source spirit, but a better…
