KDL TECH applications

Download the applications

Every KDL tool is either an application to install on your computer, or a web app to use directly in your browser. The difference is shown clearly for each one, along with the right file for your system (Windows, macOS or Linux).

⤓ Application to install

A file to download and then open. The app runs on your machine, with no account and no cloud: your data never leaves your computer. Choose the file for your system below.

Web app (nothing to install)

Opens in your browser, on any device, with no download. Just click the link.

01 · To install on your computer

Applications to download

Download the file that matches your system. Windows, macOS (recent Apple chip or Intel processor) and Linux. 100% local, free.

02 · To use in the browser

Web apps — nothing to install

These tools open directly in your browser, on a computer, tablet or phone.

KDL QR

Web appFree

Generate a clean QR code for a link, a contact or a text, directly in your browser.

KDL Pass (web)

Web appFree

Strong password generator, computed in your browser — nothing is sent over the Internet.

03 · For developers and administrators

Command-line tool

A script to run in a terminal. For people who use npm every day — if you don't know what npm is, this section isn't for you.

KDL Supply Check

Terminal Free — MIT Free

Detects on your machine the traces of npm worms from the Shai-Hulud / ChainDrop family — attacks that spread through the packages you install and steal your GitHub, npm, cloud and AI tokens.

The reflex that destroys your data These worms plant a watcher that monitors the stolen token and triggers the wipe when you revoke it. Changing your passwords first is what sets off the payload. This tool looks for that watcher before anything else and stops you in time.
bash
# download, read the script, then run it $ curl -fsSL https://raw.githubusercontent.com/Kdl-Tech/kdl-supply-check/main/kdl-supply-check.sh -o kdl-supply-check.sh $ less kdl-supply-check.sh $ bash kdl-supply-check.sh

No dependencies, no network calls, changes nothing without the --nettoyer option. Linux, macOS and WSL. Written after auditing an entire fleet during the night of the 4 August 2026 attack — all six machines were clean, but checking took hours.

How to open a downloaded program

Windows

Double-click the .exe file. If Windows shows "Windows protected your PC", click More info then Run anyway — the app isn't signed by a paid publisher, but its checksum is published below.

macOS

Take the Apple (M1/M2/M3…) version for a recent Mac, or Intel for an older Mac. On first launch: right-click the app → Open, then confirm (Gatekeeper bypass for an unsigned app).

Linux

Make the file executable (chmod +x) then run it. The private browser is provided as an AppImage: a single file, nothing to install.

🔒 Your data

These applications run locally. The only exception is the KDL Privacy browser : it browses the Internet and checks for updates, that's its purpose. The others open a page on your own computer (address 127.0.0.1) — no data is sent over the Internet.

SHA-256 checksums for all files: SHA256SUMS.txt — or let us guide you: check my download.

Do these tools help you out ? ☕

All these applications are free, with no ads and no data collection. We build them in our own time, from Guadeloupe. If one of them has been useful to you, you can buy us a coffee — it's entirely optional and unlocks nothing.
