As a developer, I often run into small tasks like decoding Base64, generating a hash, or formatting code.They are simple things, but they always show up at some point. Each time, I would go through the same routine: search online, skip past ads, find a site that seems usable, do the job, and close the tab.It’s not a big problem, just a bit distracting.I also tried relying on the command line, but sometimes I would forget the exact command or need to look it up again. Even small interruptions can break your flow.And honestly, these are the kinds of utilities that shouldn’t require accounts or paid plans. You just want them to be there when you need them.So I built 0xF, a lightweight open-source developer toolkit that runs entirely in the browser. The tools follow clear, rule-based behavior, and everything is processed locally.The project is free and open source. Feedback is always welcome.
