MacHTTP is a web server designed to run on the classic Mac OS versions 7.x through 9.x.[1][2]: 65 Written by software developer Chuck Shotton, it was the first ever web server for Mac OS.[3]: 181 It was originally released as shareware in 1993 but was commercialized starting in November 1994 with version 2.0 through Biap Systems.[4][5] It was later commercialized as WebSTAR, sold originally by StarNine and later bought by Quarterdeck Corporation; both companies continued to offer MacHTTP as a freeware version of WebSTAR.[6] Both MacHTTP and WebSTAR were the predominant web server software for Macintosh computers through to the late 1990s.[7] It is now available in source code form from SourceForge and GitHub under the Perl Artistic License. The current version is 2.6.1.[8] It is still used on some older Macintosh hardware.[9]
The program runs on Mac OS X under the Classic Environment, but has not been ported to run natively on Mac OS X.[9] It has functionally been replaced with the Apache web server.[10]
