Lynx is a customizable text-based web browser for use on cursor-addressable character cell terminals. , it is the oldest web browser still being maintained, having started in 1992.
Lynx was a product of the Distributed Computing Group within Academic Computing Services of the University of Kansas, and was initially developed in 1992 by a team of students and staff at the university (Lou Montulli, Michael Grobe and Charles Rezac) as a hypertext browser used solely to distribute campus information as part of a Campus-Wide Information Server and for browsing the Gopher space. Beta availability was announced to Usenet on 22 July 1992. In 1993, Montulli added an Internet interface and released a new version (2.0) of the browser.
the support of communication protocols in Lynx is implemented using a version of libwww, forked from the library's code base in 1996. The supported protocols include Gopher, HTTP, HTTPS, FTP, NNTP and WAIS. Support for NNTP was added to libwww from ongoing Lynx development in 1994. Support for HTTPS was added to Lynx's fork of libwww later, initially as patches due to concerns about encryption.
Garrett Blythe created DosLynx in April 1994 and later joined the Lynx effort as well. Foteos Macrides ported much of Lynx to VMS and maintained it for a time. In 1995, Lynx was released under the GNU General Public License, and is now maintained by a group of volunteers led by Thomas Dickey.
Browsing in Lynx consists of highlighting the chosen link using cursor keys, or having all links on a page numbered and entering the chosen link's number. Current versions support SSL and many HTML features. Tables are formatted using spaces, while frames are identified by name and can be explored as if they were separate pages. Lynx is not inherently able to display various types of non-text content on the web, such as images and video, but it can launch external programs to handle it, such as an image viewer or a video player.
Unlike most web browsers, Lynx does not support JavaScript, which many websites require to work correctly.
