Become a sponsor to Jeronimo Colon III

listmy.info shows you exactly what your browser reveals: parsed browser, OS, and device; your raw user agent; your public IP and rough location; the request headers the server actually sees; plus screen, hardware, timezone, and more. Every value is labeled by where it came from whether read in your browser or seen by the server.

What sets it apart is what it doesn't do. No tracking, no cookies, no analytics, no third-party scripts, and nothing about your visit is ever persists indefinitely or sold. We clean whatever AWS infrastructure logs weekly and don't peak at them. It's meant to be the one tool you can trust to tell you the truth about your own data, because it keeps none of it.

It's the first of a planned suite of small, privacy-first developer tools built the same way.

Where sponsorship goes: first and foremost - straight to the hosting bill. Any leftovers goes to supporting maintenance and other developer projects. Your support keeps listmy.info free, ad-free, and tracker-free - and funds the next tools in the line.
