About devtools.nicxon.tech

devtools.nicxon.tech is a small collection of 13 developer utilities — formatters, converters, encoders, and inspectors for the data formats you run into every day. It is built and maintained by Nicodemus Muema, a software and security engineer based in Nairobi, Kenya.

Why it exists

Most online “dev tools” sites paste your input into a form and send it to a server you don’t control. For a throwaway string that’s harmless. For a production config file, an access token, a customer export, or a signed JWT, it is a data-handling problem you shouldn’t have to think about. Every tool here does its work in your browser using standard Web APIs, so the question of who else can see your input doesn’t arise.

The second reason is speed and focus. Each tool is one static page with one job, no sign-up wall, no modal, and no ten-step onboarding. Bookmark the ones you use and they load instantly.

How it’s built

The site is generated with Astro and served as static files. Interactive widgets are small vanilla-JavaScript islands that hydrate on view. Cryptographic operations use the browser’s SubtleCrypto implementation; parsing and conversion use a handful of well-known open-source libraries bundled into the page. There is no analytics product that sets cookies, and there is no server that receives your tool input.

Contact & corrections

Found a bug, a wrong result, or an explanation that’s misleading? That’s worth an email — see the contact page. Corrections to the technical write-ups are especially welcome.

Roadmap

Planned additions include a TOML converter, a JSON Schema generator from a sample document, an .env parser, and a SQL formatter. If you want one of those sooner, say so.
