Features

• Session Manager For configuring and bookmarking connections, bundled with an up-to-date directory of over 1,700 MUDs and BBSs.

• Advanced Telnet Support for popular BBS and MUD Protocols

• WebSocket support for BBS and MUD websocket subprotocols, TELNETS (Telnet + SSL), and SSH protocols are also supported.

• MUD Features Easy-to-use TUI interface to create macros, triggers, highlights, room mapping, fast travel, random walk, autodiscover, progress bars, chat, and captures through a common Command interface, or advanced programming with asyncio Python Scripting.

• BBS/Scene Art support for CP437, PETSCII, ATASCII, iCE colors, by translation of ANSI color codes and legacy encodings to modern 24-bit color codes and terminal encoding (usually utf-8).

• Graphic Fonts render BBS bitmap fonts (CP437, Topaz, MicroKnight, P0T NOoDLE, and all 45 SyncTERM fonts) using kitty/sixel graphics, providing perfect retrocomputing bitmap font display on modern terminals.

Built using Python libraries telnetlib3, blessed, textual, wcwidth, asyncssh, websockets, and numpy.
