Arachne is a full-screen Internet suite containing a graphical web browser, email client, and dialer. Originally, Arachne was developed by Michal Polák under his xChaos label, a name he later changed into Arachne Labs. It was written in C and compiled using Borland C++ 3.1. Arachne has since been released under the GPL as Arachne GPL.
Arachne primarily runs on DOS-based operating systems, but includes builds for Linux as well. The Linux version relies on SVGALib and therefore does not require a display server.
Arachne supports many file formats, protocols and standards including video modes from CGA 640×200 in monochrome to VESA 1024×768 in high color mode (65,536 colors). It is designed for systems that do not have any windowing systems installed.
The first version of Arachne with a known release date was 1.0 Beta 2, which was released on 22 December 1996. The final and official version by Arachne Labs was 1.70R3 for DOS (released 22 January 2001) and 1.66 beta for Linux (released 20 July 2000). While there have been several more DOS versions, Linux development lay dormant until 24 May 2008 when a beta version 1.93 for Linux was released. The current DOS version, maintained by Glen McCorckle, is 1.97 as of 4 March 2013.
