About Devbelt

What it is

Devbelt is a collection of everyday developer utilities: a JSON formatter, a Base64 encoder, a URL encoder, a JWT decoder, a JSON to CSV converter, and more on the way. These are the small tools you reach for a dozen times a week without thinking about it.

The goal is not to have hundreds of them. It is to make the ones that matter genuinely good, explain how they work, and let them feed into each other so you can stay in one place instead of hopping between five different sites.

The idea behind it

Three things shape every tool here. Fast, so it responds the instant you paste something in. Private, so your data is processed in your browser and never sent to a server. Connected, so the output of one tool can move into the next without copy-pasting between tabs.

Why the tools run in your browser

Most online dev tools send whatever you paste to their servers to do the work. That is fine for a throwaway string, but not for a production API response, an auth token, or a data export with real people in it.

Devbelt does the work in your browser with JavaScript, so that data never leaves your machine. It is not a promise you have to take on faith. It is how the tools are built, and you can confirm it by watching your network tab while you use them.

Who makes it

Devbelt is built and maintained by an independent developer. It is a personal project rather than a company, with no ads, no accounts, and no tracking.
