Background

Arachne is currently the most advanced graphical web browser available for DOS as it supports many file formats, protocols and standards. It is also capable of displaying between CGA 640×200, two color and VESA 1024×768, high color modes. Arachne is designed for systems which do not have any windowing systems installed.^[3]

Arachne has image support for JPEG, PNG, BMP and animated GIF. It contains a subset of HTML 4.0 and CSS 1.0, including full support for tables and frames.^[4] FTP, NNTP for USENET forums, POP3, and SMTP are a few protocols which Arachne can handle. Arachne includes a full-fledged TCP/IP connection suite, which has support for some dial-up and ethernet connections. However, Arachne currently has no support for JavaScript and SSL. Arachne can also be expanded with the use of addons for such tasks as watching DivX movies, playing MP3 files, IRC chat, RSS, and viewing PDF documents.

The first release of Arachne with a known release date was 1.0 Beta 2 which came out 22 December 1996. The final 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 DOS versions ^[5] Linux development lay dormant until May 24, 2008 when a stable version, 1.93, of both DOS ^[6] and Linux ^[7] branch was released.

Embrowser

xChaos software licensed full source code of Arachne to Caldera UK. People from Caldera added animated GIFs and Novell dialer, completely changed the design of the browser, implemented their own support for frames, and succeeded in compiling it as a 32-bit protected mode application (using DJGPP, GNU compiler for DOS),^[9] while Arachne is a 16 bit application at the moment. This program was sold as DR-WebSpyder; the name was to associate it with DR DOS, which Caldera owned at the time. Later, when Caldera had transferred DR-DOS to its branch company Lineo, the browser was renamed Lineo Embrowser.^[10] A 32-bit protected mode (DPMI) version of Arachne is available but still needs some development.
