CERN httpd (later also known as W3C httpd) was a web server (HTTP) daemon originally developed at CERN from 1990 onwards by Tim Berners-Lee, Ari Luotonen[2] and Henrik Frystyk Nielsen.[1] Implemented in C, it was the first ever web server software[3] and went live on December 25th 1990.[4]


This NeXT Computer used by Tim Berners-Lee at CERN became the world's first web server

CERN httpd was originally developed on a NeXT Computer running NeXTSTEP, and was later ported to other Unix-like operating systems, OpenVMS and systems with unix emulation layers, e.g. OS/2 with emx+gcc. It could also be configured as a web proxy server.[1][3] Version 0.1 was released in June 1991.[5] In August 1991, Berners-Lee announced in the Usenet newsgroup alt.hypertext the availability of the source code of the server daemon and other World Wide Web software from the CERN FTP site.[6]

The original, first generation HTTP server which some call the Volkswagen of the Web.[7]

The server was presented on the Hypertext 91 conference in San Antonio and was part of the CERN Program Library (CERNLIB).[8][9][10]

Later versions of the server are based on the libwww library.[2] The development of CERN httpd was later taken over by W3C, with the last release being version 3.0A of 15 July 1996.[1] From 1996 onwards, W3C focused on the development of the Java-based Jigsaw server.[11]

The initial version was public domain software; the last one was under an MIT license.[12]
