This is the website for NetHack 4. If you're looking for more information, try reading the FAQ.

The latest version of NetHack 4 is 4.3-beta2. See the release page for information or to download it.

This is also the main public server for NetHack 4. You can play online via connecting to nethack4.org via telnet. (ssh access has been disabled because it caused too many security issues.)

Resources you might be interested in:

• The FAQ for NetHack 4;
• The philosophy behind the game;
• Our bug tracker (which can also be used for code contributions and feature requests)
• The source repository (clone with git clone http://nethack4.org/media/nethack4.git);
• The page about NetHack 4 on the NetHack wiki;
• or the website for NetHack 3.6.0 and earlier (what is commonly known as "vanilla NetHack").

Other projects

This site also hosts a blog which talks about NetHack and roguelike gameplay and development, and some projects tangentially related to NetHack 4:

• aimake is a build system for C originally developed for NetHack 4;
• jettyplay is a program for playing back terminal recordings (ttyrec), which are frequently used to record games of NetHack or other roguelikes.

Contact

You can contact the server admin (who also runs this website) via email (the username is ais523, and the domain name is the same as this website). I'm occasionally on IRC too, in the NetHack-related channels on irc.libera.chat.
