The DOS graphical web browser and Internet suite written by Michael Polák is Arachne.
Arachne was developed under Polák’s xChaos label and first appeared in the 1990s as more than a browser: it also included email, dialing, and networking tools. Written in C and compiled with Borland C++ 3.1, it was designed for DOS computers that often lacked a conventional windowing system. Linux builds later used SVGALib so the program could run without a full display server.
Its capabilities were ambitious for DOS. Arachne supported image formats such as JPEG, PNG, BMP, and animated GIF, along with parts of HTML 4.0 and CSS 1.0. Its Internet suite included FTP, Usenet through NNTP, POP3, SMTP, Gopher, and TCP/IP support for dial-up and Ethernet connections.
Arachne is often confused with text browsers such as Lynx or Links, but it was graphical. It also lacked modern features including JavaScript, Java, and SSL. The first known dated beta appeared on December 22, 1996.
