Instant WebKiosk/UB, Unrestricted Browsing, is an operating system designed for web kiosks and multi-user web workstations (caf├Ęs, offices, schools, hotels, hospitals, libraries) on standard (even diskless) PC hardware.

It is a “live” (no installation required because it boots from USB keys), browser-only (only the browser interface will show up) distribution of Linux Debian.


Instant WebKiosk/UB is a fully customizable operating system for Internet browsing purposes, which protects privacy: users can modify its settings runtime but after a reset the operating system defaults to original values and users’ informations are completely destroyed. Closing browser window also resets system – in a less secure but quicker manner. It is hacker proof and completely immune to viruses and malware.

Only persistent settings are always preserved: network, localization, video, sound and printer configurations persist across reboots. Browser state (custom settings, extension, bookmarks, history and so on) can also be optionally saved by the admin.

Instant WebKiosk/UB makes use of Google Chromium as Internet browser and it features PDF, images and video viewing, office files and compressed files support; it features full “i18n” (internationalization) including CJ input methods.

It supports printing (plug&print for most common USB printers – network printers need to be manually set) and both wired (with DHCP / static) and wireless networks (DHCP) in order to access the Internet. System parameters are set by an user-friendly web interface. Adobe Flash support has been dropped by latest Chromium version, and HTML5 videos are now used instead.
