ToastStuntThe server behind Miriani and ChatMUD, this fork of Stunt features 64-bit integers, SQLite, PCRE, simplex noise, argon2id hashing, improved waifs, basic threading support, telnet IAC capture, HAProxy Proxy rewrite support, and numerous other enhancements and builtin functions.Local Copy
LambdaMOOThe official LambdaMOO server. (Old SourceForge page) [Local copy is 1.8.1]Local Copy
Stunt Server (Git)Adds multiple inheritance, a native ordered map datatype, JSON parsing, new cryptographic operations, and probably more by the time you read this. [Local copy is release 8. Downloaded 6/9/12]Local Copy
GammaMOOA fork of LambdaMOO with minor additions to matching, cryptography, and syntactic sugar. [Local copy is 1.8.1g3r1]Local Copy
LambdaMOO+fooNo experience. Local copy is several years old and of unknown versioning.Local Copy
HellCore ServerThe server provided with HellCore. Contains hashes, profiling, and other game-related modifications. [Local copy is 1.10.4]Local Copy
EtaMOOA reimplementation of the LambdaMOO server in Haskell. Features multi-threading, LMDB database storage, 64-bit integers, and more. Compatible with LambdaMOO databases. [Local copy is]Local Copy
WaverousA fork of the LambdaMOO server aiming, among other things, to utilize C++ and add a number of compile-time addon features. NOTE: These features were added to Stunt and this fork has been discontinued.Local Copy
WinMOOAn antiquated port of the LambdaMOO server to Windows. NOTE: You would achieve better results installing Microsoft's Windows Subsystem for Linux and compiling the regular ToastStunt or LambdaMOO server.Local Copy
MacGoesMOOAn antiquated pre-Intel Macintosh MOO server. Hosted locally as I have no other sources to point to.Help
moorA work-in-progress re-implementation of the LambdaMOO server in Rust. As of 2023-09-23, many core features are not functional, including read(), background task resumption, do_command(), performance, encode/decode binary, open_network_connection(), listen(), etc. Consider this experimental.

Core Databases
ToastCoreBased on the 2018 LambdaCore, this database has been modified to utilize the features found in ToastStunt. This includes updating core verbs with server function equivalents, ANSI, MCP, Argon2id password hashing, parent waif / anon objects, built-in type prototypes, Stunt object serializer, MCP SimpleEdit with //-style comments, object-less $recycler, and general cleanup. This can be used as a starting point for a new MOO or as a reference for integrating ToastStunt features. NOTE: This database requires the ToastStunt server to run.Changelog
LambdaCore 2018A new LambdaCore that I created in 2018 to merge the miscellaneous changes that have taken place since 2004. NOTE: This is not an official release.Changelog
LambdaCoreThe official LambdaCore database. Includes the basics for getting started. [Local copy is May 17, 2004.]Local Copy
JHCore (Sourceforge)Based off of LambdaCore, this core includes several enhancements in pronoun substitution, the building system, virtual furniture and other niceties, MCP, modules, and many others. The link to the left is a live core extraction from Waterpoint. You will need a character. [Local copy is an extracted core created in November 2020]Local Copy
enCore (Sourceforge)An educational MOO core.Local Copy
RPGCoreA core with features needed for those creating Role Playing Games similar to MUDs.Local Copy
GhostCoreA core centered around RPG. (I think.)Local Copy
Hero CoreRPG database built from minimal.db. (Formerly Murpg)Local Copy
HellCoreA core database extracted from HellMOO. Bundled with server source.Local Copy
FooCoreI really have no experience with this one. The local copy is 1.1 beta, which is of an indeterminate age.Local Copy
Ultraminimal.dbZig's improvement to the absolute minimum available: The system object (#0).
Minimalest.dbThe (almost) absolute minimum available: The system object (#0) and Wizard (#1). Readme
Minimal.dbThe minimal database shipped with the server. Slightly more reasonable: Three objects, two verbs.Readme
GondolinCoreNot certain what it actually is. This copy is from around 2003. Supplementary material came from the original FTP.Extras
SyrinniaCoreAgain, not certain what it is. This copy is also from 2003.Local Copy
LiverpoolCoreThis was with Gondolin and Syrinnia. No idea what it is, but it's circa 2003.Local Copy
OmegaCoreA LambdaCore updated for Stunt: "It has ANSI and the basic MCP packages bootstrapped and contains various improvements over the original database." [Local copy based on commit 786c96a on Jun 30]Local Copy
QuestCore (v1) (v2)A core focused on RPG creation. Version 2 includes @oracle for generating random areas. Additional documentation can be found here.Local Copy

ChaosMOOThis one is more of historic interest. ChaosMOO was a MOO where everybody was, by default, created as a wizard. I believe it went down around 1993. NOTE: This probably shouldn't be used as a core database.Local Copy
Zen 1 / Zen 2Not entirely sure what this is about, but it dates to around the time of ChaosMoo and old MOO-Cows archives refer to it as a "sick idea", so results may vary. NOTE: This probably shouldn't be used as a core database.Readme

Unicode for 1.8.1Quoting from the author: "I embarked on a project in late January 2002 to permit a LambdaMOO server to speak in a language other than ASCII. Specifically, the MOO server had been designed to discard text outside the bottom half of the ASCII table (< 0x80), unless in a special 'binary' input/output mode. I took the lazy programmer's approach to Unicode, and converted the server to treat input and output strings as UTF-8 encoded. The results make me spectacularly happy."Local Copy
Stunt SQLiteMy extension to add SQLite capabilities to the Stunt server.Local Copy
Stunt PCREMy extension to add Perl Compatible Regular Expressions to the Stunt server.Local Copy
