Uzbl follows the UNIX philosophy - "Write programs that do one thing and do it well. Write programs to work together. Write programs to handle text streams, because that is a universal interface."

* very minimal graphical interface. You only see what you need
* what is not browsing, is not in uzbl. Things like url changing, loading/saving of bookmarks, saving history, downloads, ... are handled through external scripts that you write
* controllable through various means such as fifo and socket files, stdin, keyboard and more
* advanced, customizable keyboard interface with support for modes, modkeys, multichars, variables (keywords) etc. (eg you can tweak the interface to be vim-like, emacs-like or any-other-program-like)
* focus on plaintext storage for your data and configs in simple, parseable formats
* Uzbl keeps it simple, and puts you in charge.

Perspectives is a new approach to help clients securely identify Internet servers in order to avoid "man-in-the-middle" attacks.

The concept is similar to an internet browser. But it is intended for the use in industrial process visualization.
