About nex9

A small, independently-run toolbox of free browser-based utilities.

nex9.de is built and maintained as a solo project. The goal is simple: give developers and everyday users fast, no-nonsense tools that do exactly one job, with no account walls, no intrusive tracking, and no artificial delays.

How it's built

Every tool on this site is plain HTML, CSS and JavaScript — no frameworks, no build step, no third-party script dependencies. Anything you type into a tool is processed locally in your browser; nothing is uploaded to a server. This keeps the site fast and keeps your data yours.

How the site is funded

nex9.de is supported by lightweight, clearly labeled advertising. There are no premium tiers, no paywalls, and no email sign-up requirements — every tool is free to use for everyone.
